The critical current of disordered superconductors near 0 K

Nature Communications, 2020
Increasing the critical current of superconductors has been a central scientific effort, but the fundamental understanding of critical currents near 0 K is lacking. Here, Doron et al.

Higgs mode and its decay in a two dimensional antiferromagnet

, 2017
Condensed-matter analogs of the Higgs boson in particle physics allow insights into its behavior in different symmetries and dimensionalities. Evidence for the Higgs mode has been reported in a number of different settings, including ultracold atomic ...

Spin–orbit torque switching in a T-type magnetic configuration with current orthogonal to easy axes

Nature Communications, 2019
Spin-orbit torque (SOT) induced magnetization switching facilitates all electric multi-state spin memories and spin logic devices. Here the authors show a new SOT field-free switching mode where the perpendicular layer with tilted easy axis is coupled to

Tunable electronic structure and magnetic anisotropy in bilayer ferromagnetic semiconductor Cr2Ge2Te6

Scientific Reports, 2021
The emergence of ferromagnetism in two-dimensional van der Waals materials has aroused broad interest. However, the ferromagnetic instability has been a problem remained.

Of Matters Condensed [PDF]

arXiv, 2015
The American Physical Society (APS) March Meeting of condensed matter physics has grown to nearly 10,000 participants, comprises 23 individual APS groups, and even warrants its own hashtag (#apsmarch). Here we analyze the text and data from March Meeting abstracts of the past nine years and discuss trends in condensed matter physics over this time ...

Abelian and Non-Abelian Monopole Configuration in Condensed Matters [PDF]

arXiv, 2020
We discuss the Abelian and non-Abelian monopoles which could exist in condensed matters. We show how the Dirac monopole can be regularized by the charge screening, and argue that the Dirac monopole of mass of hundred meVs could exist in dielectric condensed matters.

Equilibrium spin currents: Non-Abelian gauge invariance and color diamagnetism in condensed matter

, 2008
The spin-orbit (SO) interaction in condensed matter can be described in terms of a non-Abelian potential known in high-energy physics as a color field. I show that a magnetic component of this color field inevitably generates diamagnetic color currents ...

Kinetic origin of hysteresis and the strongly enhanced reversible barocaloric effect by regulating the atomic coordination environment

NPG Asia Materials
Hysteresis is an inherent property of first-order transition materials that poses challenges for solid-state refrigeration applications. Extensive research has been conducted, but the intrinsic origins of hysteresis remain poorly understood.

Preparing high-concentration individualized carbon nanotubes for industrial separation of multiple single-chirality species

Nature Communications, 2023
Industrial production of single-chirality carbon nanotubes is critical for their applications in high-speed and low-power nanoelectronic devices, but both their growth and separation have been major challenges.
