Electric-field controlled nonlinear anomalous Nernst effect in two-dimensional time-reversal symmetric systems
Ying-Li Wu, Xiao-Qin Yu
It's established that the nonlinear anomalous Nernst effect (NANE), originating from Berry curvature near the Fermi energy, is symmetry-permitted only when a single mirror symmetry…
Intrinsic nonlinear valley Nernst effect in the strained bilayer graphene
Ying-Li Wu, Jia-Liang Wan, Xiao-Qin Yu
We theoretically analyze the nonlinear valley Nernst effect (NVNE) as the second-order response of temperature gradient through the semiclassical framework of electron dynamics. Ou…
The unidirectional Seebeck detection of the Néel vector in the two-dimensional tetragonal -symmetric antiferromagnetic materials
Ya-Ting Xiao, Ying-Li Wu, Jia-Liang Wan +1
The efficient detection of the reversal (180 rotation) of the Néel vector is one of the crucial tasks in antiferromagnetic spintronics. Here, we propose a thermal approac…
Extrinsic nonlinear acoustic valley Hall effect in the massive Dirac materials
Jia-Liang Wan, Ying-Li Wu, Ke-Qiu Chen +1
The nonlinear acoustic valley Hall effect (AVHE), a recently discovered novel acoustically driven phenomena, has sparked extensive interests in valleytronics. So far, only the intr…
Strongly enhanced nonlinear acoustic valley Hall effect in tilted Dirac materials
Jia-Liang Wan, Ying-Li Wu, Ke-Qiu Chen +1
It has been recently established that a nonlinear valley current could be generated through traveling a surface acoustic wave (SAW) in two-dimensional Dirac materials. So far, the…
