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…
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…
Generation of Bell, W and GHZ states via exceptional points in non-Hermitian quantum spin systems
Ci. Li, Zhi. Song
We study quantum phase transitions in non-Hermitian XY and transverse-field Ising spin chains, in which the non-Hermiticity arises from the imaginary magnetic field. Analytical and…
