Enhancing delocalization and entanglement in asymmetric discrete-time quantum walks
Hao Zhao, Qiyan He, Fengzhi Yang +8
In this paper, we investigate the enhancement of delocalization and coin-position entanglement in asymmetric discrete-time quantum walks (DTQWs). The asymmetry results from asymmet…

Purity-dependent Lorenz number, electron hydrodynamics and electron-phonon coupling in WTe
Wei Xie, Feng Yang, Liangcai Xu +3
We present a study of electrical and thermal transport in Weyl semimetal WTe down to 0.3 K. The Wiedemann-Franz law holds below 2 K and a downward deviation starts above. The d…
