Suppression of Non-Hermitian Skin Effect by Pseudomagnetic Field in Honeycomb Lattice
Kai Shao, Kun Luo
Magnetic suppression of the non-Hermitian skin effect (NHSE) offers a viable route for its control. While the NHSE has been realized in various classical-wave platforms, only pseud…
Altermagnetic Spin Precession and Spin Transistor
Li-Shuo Liu, Kai Shao, Hai-Dong Li +3
Altermagnets hold great potential for spintronic applications, yet their intrinsic spin dynamics and associated transport properties remain largely unexplored. Here, we investigate…
Universal valley filtering via uniform dissipation and velocity contrast
Sijie Yue, Wentao Xie, Kai Shao +6
Valley, as a ubiquitous degree of freedom in lattices, has found wide applications in both electronic and classical-wave devices in recent years. However, achieving valley-polarize…
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…
