Unusually high phonon thermal conductivity in the Weyl semimetal TaP: A comparative study with TaAs
Xianyong Ding, Xin Jin, Dengfeng Li +5
In many metals, thermal transport is often dominated by electrons, although the lattice contribution can remain appreciable depending on the material. Here, through rigorous first-…
Gap solitons of the Wannier and Bloch types in spin-orbit-coupled Bose-Einstein condensates with a moiré lattice
Jun-Tao He, Xue-Ping Cheng, Xin-Wei Jin +3
Gap solitons (GSs) bifurcating from flat bands, which may be represented in terms of Wannier functions, have garnered significant interest due to their strong localization with ext…
Phonon-Dominated Thermal Transport and Large Violation of the Wiedemann-Franz Law in Topological Semimetal CoSi
Luyao Zhong, Xin Jin, Mingquan He +4
The Wiedemann-Franz (WF) law, relating the electronic thermal conductivity () to the electrical conductivity, is vital in numerous applications such as in the design of…
Anharmonicity-driven phonon avoided crossing and anomalous thermal transport in nodal-line semimetal ZrSiS
Xin Jin, Qingqing Zhang, Dengfeng Li +8
Understanding thermal and electrical transport in topological materials is essential for advancing their applications in quantum technologies and energy conversion. Herein, we empl…
Impact of Thermal Effects on the Current-Tunable Electrical Transport in the Ferrimagnetic Semiconductor MnSiTe
Yiyue Zhang, Xin Jin, ZeYu Li +8
In the ferrimagnetic semiconductor MnSiTe, a colossal magnetoresistance (CMR) is observed only when a magnetic field is applied along the magnetic hard axis ($\mathbf{H…
Zeptosecond free-electron compression through temporal lensing
Xin Jin, Cruz I. Velasco, F. Javier GarcÃa de Abajo
The pursuit of ever-shorter time scales is a frontier in modern physics, exemplified by the synthesis of attosecond light pulses -- an achievement made possible by coherently super…
