Ferroelectric Band Twinning from Pair-State Symmetry
Shibo Fang, Jianhua Wang, Zhenzhou Guo +7
Ferroelectric switching provides a nonvolatile way to control electronic structures, but a general symmetry rule connecting the full Bloch bands of two switchable polarization stat…
Crystal Symmetry Selected Pure Spin Photocurrent in Altermagnetic Insulators
Ruizhi Dong, Ranquan Cao, Dian Tan +1
The generation of time-reversal-odd spin-current in metallic altermagnets has attracted considerable interest in spintronics. However, producing pure spin-current in insulating mat…
Photostrictive Effect and Structure Phase Transition via Nonlinear Photocurrent
Ruixiang Fei, Li Yang
The phenomena of crystal size changes and structural phase transitions induced by light irradiation have garnered significant interest due to their potential for tuning and control…
Ab initio study of proton-exchanged LiNbO3(I): Structural, thermodynamic, dielectric, and optical properties
Lingyuan Gao, Robert B. Wexler, Ruixiang Fei +1
Using first principles calculations, we study the ground-state structure of bulk proton-exchanged lithium niobate, which is also called hydrogen niobate and is widely used in waveg…
PT-symmetry enabled spin circular photogalvanic effect in antiferromagnetic insulators
Ruixiang Fei, Wenshen Song, Lauren Pusey-Nazzaro +1
The short timescale spin dynamics in antiferromagnets is an attractive feature from the standpoint of ultrafast spintronics. Yet generating highly polarized spin currents at room t…
Switchable enhanced spin photocurrent in Rashba and cubic Dresselhaus ferroelectric semiconductors
Ruixiang Fei, Shuaiqin Yu, Yan Lu +2
Generating and controlling spin current (SC) are of central interest in spin physics and applications. To date, the spin-orbit interaction (SOI) is an established pathway to genera…
