A survey of heavy-antiheavy hadronic molecules Dong Xiang-Kun, Guo Feng-Kun, Zou Bing-Song Progress in Physics    2021, 41 (2): 65-93.   DOI: 10.13725/j.cnki.pip.2021.02.001 Abstract （1195）      PDF （1088KB）（10897）       Many efforts have been made to reveal the nature of the overabundant resonant structures observed by the worldwide experiments in the last two decades. Hadronic molecules attract special attention because many of these seemingly unconventional resonances are located close to the threshold of a pair of hadrons. To give an overall feature of the spectrum of hadronic molecules composed of a pair of heavy-antiheavy hadrons, namely, which pairs are possible to form molecular states, we take charmed hadrons for example to investigate the interaction between them and search for poles by solving the Bethe-Salpeter equation. We consider all possible combinations of hadron pairs of the S-wave singly-charmed mesons and baryons as well as the narrow P-wave charmed mesons. The interactions, which are assumed to be meson-exchange saturated, are described by constant contact terms which are resummed to generate poles. It turns out that if a system is attractive near threshold by the light meson exchange, there is a pole close to threshold corresponding to a bound state or a virtual state, depending on the strength of interaction and the cutoff. In total, 229 molecular states are predicted. The observed near-threshold structures with hidden-charm, like the famous X(3872) and Pc states, fit into the spectrum we obtain. We also highlight a  ΛcΛc  bound state that has a pole consistent with the cross section of the e+e-→ ΛcΛc  precisely measured by the BESIII Collaboration. Related Articles | Metrics

A Brief History of Electronic Development SHI Feng , LIU Jin-hua , ZHANG Ling-cui , XU Yue , LOU You-xin , SHEN Yan , ZHAO Jin-bo Progress in Physics    2025, 45 (2): 79-104.   DOI: 10.13725/j.cnki.pip.2025.02.003 Abstract （269）      PDF （516KB）（747）       Electron is an inseparable part of atom. The ancients believed that atoms could not be divied, and it was not until the late 19th century that Thomson discovered the existence of electron, which proved that atom is redividable. After that, the complex and challenging journey to uncover the volatility of electrons, electron spin, and positrons led to groundbreaking discoveries, which resulted in numerous of Nobel Prizes were awarded in Physics. The discovery of electron played an important role in promoting the birth of quantum mechani. It was through the meticulous examination of atomic structure models that the scientists progressively ventured into the realms of quantum mechanics and quantum field theory. Similarly, electrons have played a positive role in promoting our understanding of various materials, leading to the development of to many theories, such as Lorentz’s free electron theory, Sommerfeld model, and band theory. Especially band theory has led to a revolution in modern electronic technology, ushering humanity into the information age.  Related Articles | Metrics

In this review, we focus on the complex nonlinear dynamic characteristics of spin-wave modes generated by SHNOs in the various ferromagnetic/nonmagnetic (FM/NM) bilayer systems with an extended free layer. Based on the abundantly previous experimental results obtained by combining microwave spectroscopy and micro-focused Brillouin light scattering techniques, as well as micromagnetic simulation, we detailedly describe and summarize the experimental parameters dependent magnetic dynamics of SHNOs with different device configurations and magnetic materials, such as in-plane nanogap-type, nanoconstriction-type, nanowire-type, vertical nanocontact-type SHNOs with in-plane or out-of-plane magnetization. Finally, we also discuss mutual synchronization of SHNO arrays and the potential applications in magnon-based logic devices with ultralow energy consumption and spin-based artificial neural network for neuromorphic computing in the field of artificial intelligence.

Research Progress on Two-Dimensional Multiferroic Materials and Their Magnetoelectric Properties ZHENG Hongqian , HU Ting , HUANG Chengxi , DU Yongping , WAN Yi Progress in Physics    2025, 45 (3): 105-.   DOI: 10.13725/j.cnki.pip.2025.03.001 Abstract （410）      PDF （9286KB）（825）       In recent years, multiferroic materials, which possess both ferromagnetic and ferroelectric properties, have attracted intense attention from researchers due to their novel and rich physical characteristics, as well as their broad potential applications in fields such as information storage and sensor technologies. As understanding of the properties of multiferroic materials deepens, researchers have begun to explore their behavior at smaller scales, particularly focusing on two-dimensional (2D) materials. Compared to three-dimensional (3D) materials, 2D materials, owing to their unique structural features and significant size effects, often exhibit more superior performance in terms of mechanical, optical, thermal, and magnetic properties. However, it is noteworthy that current research on 2D multiferroic materials is primarily concentrated on theoretical predictions, with experimental progress lagging behind. In this context, this paper first briefly reviews the development history of multiferroic materials, then elaborates on the characteristics and advantages of 2D materials, and discusses the potential applications of 2D multiferroic materials. Subsequently, the paper provides an overview of the current research status, covering related physical phenomena and mechanisms, experimental preparation methods, performance regulation technologies, and characterization techniques. Furthermore, this paper also enumerates potential 2D multiferroic materials predicted by theory and, based on this, delves into the challenges faced by current research and future directions for development.  Related Articles | Metrics

Recent Progress in Ultrafast Spin Dynamics in Two-Dimensional van der Waals Antiferromagnets LI Jin-yang , WU Fang-liang , ZHANG Qi Progress in Physics    2024, 44 (6): 293-308.   DOI: 10.13725/j.cnki.pip.2024.06.003 Abstract （864）      PDF （4771KB）（1114）       Antiferromagnets exhibit high-speed spin responses in the terahertz frequency range and robustness against external magnetic fields, making them promising for nextgeneration high-speed, high-density spintronic devices. Recently, two-dimensional van der Waals magnetic systems, which possess rich antiferromagnetic ground states, have gained significant attention and serve as ideal platforms for studying low-dimensional antiferromagnetic physics. Detecting and controlling ultrafast spin dynamics in two-dimensional antiferromagnetic systems will lay the foundation for high-speed spintronic device applications. Antiferromagnets have no net macroscopic magnetization, making traditional optical methods, such as magneto-optical effects, challenging for detecting antiferromagnetic order in equilibrium states. However, in non-equilibrium states, the instantaneous magnetization generated by antiferromagnetic spin dynamics allows the use of time-resolved magneto-optical Kerr effect to detect coherent spin precession in antiferromagnets. Additionally, techniques such as linear dichroism spectroscopy, terahertz emission spectroscopy, and second harmonic generation have been employed in studying the dynamics of two-dimensional antiferromagnets. This paper introduces recent experimental progress on ultrafast spin dynamics in two-dimensional van der Waals antiferromagnetic systems, and briefly describes the coherent magnon excitations and corresponding mechanisms in two-dimensional antiferromagnets, including inverse magneto-optical effects/stimulated Raman scattering, orbital excitations, and exciton coupling. Furthermore, this paper discusses the critical slowing down of spin dynamics due to spin-lattice coupling effects and the amplification of coherent acoustic phonons. Related Articles | Metrics

The exotic electronic properties of the topological Kondo insulator SmB 6 ZHAO Gan, ZHANG Ming-yuan, WANG Jia-min, ZHANG Wang, MIAO Lin Progress in Physics    2021, 41 (6): 231-.   DOI: 10.13725/j.cnki.pip.2021.06.001 Abstract （1430）      PDF （9363KB）（6002）       The topological Kondo insulator (TKI) is an intrinsic electronic correlated topological system in which the bulk bandgap is originated from the Kondo correlation. Since the theoretical idea of TKI was proposed in 2010, SmB6 was predicted to be the first candidate topological Kondo insulator. In the last decade, SmB6 was investigated extensively by various experimental methods, and the accumulated evidence confirmed that SmB6 is a topological Kondo insulator. This review article presented some key experimental evidence, including electronic transportation measurements, ARPES study of low-energy band structure, and STM characterization of the surface. We also discussed how these experimental results establish the topological narrative of SmB6. Meanwhile, some extremely exotic properties like the 3D quantum oscillations and the bulk-surface valence seperation of SmB6 are exhibited. The related physical origin is still unknown and needs extra efforts to unveil the underlying physics. Related Articles | Metrics

Two-Dimensional Transistors beyond Silicon Counterparts: From Theory to Experiment LI Hong , XU Lin , QIU Chenguang , LU Jing Progress in Physics    2025, 45 (3): 118-131.   DOI: 10.13725/j.cnki.pip.2025.03.002 Abstract （219）      PDF （2085KB）（476）       Due to the severe short-channel effects, silicon-based transistors cannot work well when the gate length is shorter than 10 nm. Moore’s law is at risk of failure. Compared to bulk semiconductor materials, two-dimensional (2D) materials own better electrostatic features and higher carrier mobilities. To describe the transport properties of transistors at the nanometer scale, the first-principles quantum transport simulation based on density functional theory coupled with non-equilibrium Green’s function method is the most precise theoretical tool. The device performances of ideal 2D transistors are predicted to surpass those of silicon-based transistors based on the first-principles quantum transport simulation, which can meet the International Technology Roadmap for Semiconductors (ITRS) and International Roadmap for Device and Systems (IRDS) requirements for the next decade and extend Moore’s law to sub-10 nm gate lengths . We review dramatic experimental breakthroughs on 2D transistors in the recent two years, including shrinking the gate length to the Angstrom scale, descending the electrode contact resistance to the quantum limit, and fabricating high-quality and ultrathin dielectric. When Ohmic contacts and high-quality ultrathin dielectric layers are simultaneously realized, theoretically predicted superior performances beyond silicon are observed in 10-nmgate InSe transistors experimentally.  Related Articles | Metrics

Spin Hall Effect of Light and Its Applications in Measurements of Physical Parameters LIU Shuo-qing , CHEN Shi-zhen , LUO Hai-lu Progress in Physics    2022, 42 (2): 35-53.   DOI: 10.13725/j.cnki.pip.2022.02.001 Abstract （2776）      PDF （8674KB）（6204）       The spin Hall effect (SHE) of light refers to the transverse spin-dependent splitting of photons with opposite spin angular momentum after the beam passes through inhomogeneous media, in the direction perpendicular to the incident plane. It can be regarded as an analogue of the SHE in electronic systems, where the spin photons and the refractive index gradient replace the spin electrons and the electronic potential, respectively. Fundamentally, the SHE of light originates from the spin-orbit interaction of photons and depends mainly on two different geometric phases, namely, the spin redirection Rytov-Vlasimirskii-Berry phase in the momentum space and the Pancharatnam-Berry phase in the Stokes parameter space. Meanwhile, the SHE of light exhibits great sensitivity to the physical parameters, and combined with quantum weak measurements, has important application prospects in fields of physical parameters measurement and optical sensing. We briefly analyze the physical origin of the SHE of light, review its recent progress in different physical systems, and present its applications in measurements of physical parameters. Finally, the possible developing trends in optical analog computing, microscopy imaging, and quantum imaging are discussed. Related Articles | Metrics
