A Magnetic Torsional Pendulum for Exploring Forced Resonance, Parametric Resonance, and Parametric Amplification
Wenqing Xie, Jiahao Wu, Yujun Shi
We present a magnetic torsional pendulum that provides a unified experimental platform for investigating forced resonance, parametric resonance, and degenerate parametric amplifica…
Revisiting Koehler's experiment of measuring the ratio of the specific heats of air by self-sustained oscillations
Yujun Shi, Xiaoting Fen
We revisit Koehler's experiment, a clever modification of Ruchardt's experiment designed to measure the ratio of specific heats of gas. However, the lengthy and dense analysis shar…
Recurrence in a periodically driven and weakly damped Fermi-Pasta-Ulam-Tsingou chain
Yujun Shi, Haijiang Ren
We report numerical evidence of Fermi-Pasta-Ulam-Tsingou (FPUT)-like recurrence in weakly damped, periodically driven alpha-FPUT chains. In narrow regions of driving amplitude and…
Discretely structured magnetic flux concentrators
Yujun Shi, Xiaoting Feng
Conventional magnetic flux concentrators (MFCs) are typically designed with solid structures, which may not be optimal for applications requiring lightweight design or material eff…
Geometric invariance from outer surfaces: Laplace-governed magnetization in the high-permeability limit
Yujun Shi
The magnetization of bodies in static fields is a textbook topic in electrodynamics, governed by Laplace equations with interface continuity (transmission) conditions. In the infin…
Phase diagrams on composition-spread FeTeSe films
Zefeng Lin, Sijia Tu, Juan Xu +9
FeTeSe, an archetypical iron-based high-temperature superconductor with a simple structure but rich physical properties, has attracted lots of attention because the…
Universal scaling of the critical temperature and the strange-metal scattering rate in unconventional superconductors
Jie Yuan, Qihong Chen, Kun Jiang +17
Dramatic evolution of properties with minute change in the doping level is a hallmark of the complex chemistry which governs cuprate superconductivity as manifested in the celebrat…
Emergent superconductivity in single crystalline films via structural engineering
Wei Hu, Zhongpei Feng, Ben-Chao Gong +15
Spinel compounds have demonstrated rich functionalities but rarely shown superconductivity. Here, we report the emergence of superconductivity in the spinel $\mathrm{MgTi}_2\mathrm…
Continuous magnetic phase transition in half-frustrated Ca2Os2O7
P. Zheng, Y. G. Shi, Q. S. Wu +8
We present the specific heat, magnetization, optical spectroscopy measurements and the firstprinciple calculations on the Weberite structure Ca2Os2O7 single crystal/polycrystalline…
