Ultrafast spintronics with geometric effects in non-adiabatic wave-packet dynamics
Matisse Wei-Yuan Tu, Li-Sheng Lin, Chung-Yu Wang +6
Motivated by the intriguing possibilities of steering ultrafast non-adiabatic processes through the geometric properties of bands in quantum materials by laser pulses, we extend a…
Revealing the non-adiabatic and non-Abelian multiple-band effects via anisotropic valley Hall conduction in bilayer graphene
Ci Li, Matisse Wei-Yuan Tu, Wang Yao
Many quantum materials of interest, ex., bilayer graphene, possess a number of closely spaced but not fully degenerate bands near the Fermi level, where the coupling to the far det…
Spin Photovoltaic Effect in Magnetic van der Waals Heterostructures
Tiancheng Song, Eric Anderson, Matisse Wei-Yuan Tu +9
The development of van der Waals (vdW) crystals and their heterostructures has created a fascinating platform for exploring optoelectronic properties in the two-dimensional (2D) li…
Giant spin transfer torque in atomically thin magnetic bilayers
Weihao Cao, Matisse Wei-Yuan Tu, Jiang Xiao +1
In cavity quantum electrodynamics, the multiple reflections of a photon between two mirrors defining a cavity is exploited to enhance the light-coupling of an intra-cavity atom. We…
Theory of wavepacket transport under narrow gaps and spatial textures: non-adiabaticity and semiclassicality
Matisse Wei-Yuan Tu, Ci Li, Wang Yao
We generalise the celebrated semiclassical wavepacket approach from the adiabatic to the non-adiabatic regime. A unified description covering both of these regimes is particularly…
Non-adiabatic Hall effect at Berry curvature hot spot
Matisse Wei-Yuan Tu, Ci Li, Hongyi Yu +1
Hot spot of Berry curvature is usually found at Bloch band anti-crossings, where the Hall effect due to the Berry phase can be most pronounced. With small gaps there, the adiabatic…
