Unified Semiclassical Theory of Nonlinear Hall Effect:Bridging Ballistic and Diffusive Transport Regime
Xinyu Liu, Haozhi Liao, Guangyun Qi +3
The nonlinear Hall effect has attracted considerable attention and undergone extensive investigation in recent years. However, theoretical studies addressing size-dependent effects…
Nonreciprocal ballistic transport in multi-layer Weyl semimetal films with surface engineering
M. H. Zou, R. Ma, S. J. Xu +4
Weyl semimetal (WSM) thin films exhibit distinct electronic properties compared to their bulk counterparts. In this study, we theoretically investigate the nonreciprocal ballistic…
Nonreciprocal Ballistic Transport in Asymmetric Bands
Minhao Zou, Hao Geng, Rong Ma +3
Nonreciprocal transport in uniform systems has attracted great research interest recently and the existing theories mainly focus on the diffusive regime. In this study, we uncover…
A Non-Hermitian Moiré Valley Filter
Kai Shao, Hao Geng, Erfu Liu +3
A valley filter capable of generating a valley-polarized current is a crucial element in valleytronics, yet its implementation remains challenging. Here, we propose a valley filter…
