The New Phase due to Symmetry Protected Piecewise Berry Phases; Enhanced Pumping and Non-reciprocity in Trimer Lattices
Xuele Liu, G. S. Agarwal
Finding new phase is a fundamental task in physics. Landau's theory explained the deep connection between symmetry breaking and phase transition commonly occurring in magnetic, sup…
Regularization of the spectral singularity in -symmetric systems by all order nonlinearities: Nonreciprocity and optical isolation
Xuele Liu, Subhasish Dutta Gupta, G. S. Agarwal
Spectral singularities are ubiquitous with PT-symmetry leading to infinite transmission and reflection coefficients. Such infinities imply the divergence of the fields in the mediu…
Photon Aided and Inhibited Tunneling of Photons
Xuele Liu, G. S. Agarwal
In the light of the interest in the transport of single photons in arrays of waveguides, fiber couplers, photonic crystals, etc., we consider the quantum mechanical process of the…
The topological system with a twisting edge band: position-dependent Hall resistance
Xuele Liu, Qing-feng Sun, X. C. Xie
We study a topological system with one twisting edge-state band and one normal edge-state band. For the twisting edge-state band, Fermi energy goes through the band three tim…
Abelian and non-abelian anyons in integer quantum anomalous Hall effect and topological phase transitions via superconducting proximity effect
Xuele Liu, Ziqiang Wang, X. C. Xie +1
We study the quantum anomalous Hall effect described by a class of two-component Haldane models on square lattices. We show that the latter can be transformed into a pseudospin tri…
Spin Nernst effect in the absence of a magnetic field
Xincheng Xie, Xuele Liu
We study the spin Nernst effect of a mesoscopic four-terminal cross-bar device with the Rashba spin-orbit interaction (SOI) in the absence of a magnetic field. The interplay betwee…
