Ferroelectric switchable altermagnetism
Mingqiang Gu, Yuntian Liu, Haiyuan Zhu +5
We propose a novel ferroelectric switchable altermagnetism effect, the reversal of ferroelectric polarization is coupled to the switching of altermagnetic spin splitting. We demons…
Magnetic geometry induced quantum geometry and nonlinear transports
Haiyuan Zhu, Jiayu Li, Xiaobing Chen +2
The combination of quantum geometry and magnetic geometry in magnets excites diverse phenomena, some critical for antiferromagnetic spintronics. However, very few material platform…
Orbital doublet driven even-spin Chern insulators
Lu Liu, Yuntian Liu, Jiayu Li +2
Quantum spin Hall insulators hosting edge spin currents hold great potential for low-power spintronic devices. In this paper, we present a universal approach to achieve a high and…
Quantum spin Hall effect protected by spin U(1) quasisymmetry
Lu Liu, Yuntian Liu, Jiayu Li +2
Quantum spin Hall (QSH) effect, where electrons with opposite spin channels are deflected to opposite sides of a two-dimensional system with a quantized conductance, was believed t…
