Characterizing topological pumping of charges in exactly solvable Rice-Mele chains of the non-Hermitian variety
Ipsita Mandal
We address the nature of the Thouless charge-pumping for a non-Hermitian (NH) generalization of the one-dimensional (1d) Rice-Mele model, considering a variety which allows closed-…

Identifying gap-closings in open non-Hermitian systems by Biorthogonal Polarization
Ipsita Mandal
We investigate gap-closings in one- and two-dimensional tight-binding models with two bands, containing non-Hermitian hopping terms, and open boundary conditions (OBCs) imposed alo…

Non-Hermitian generalizations of the Yao-Lee model augmented by SO(3)-symmetry-breaking terms
Ipsita Mandal
We investigate non-Hermitian versions of the Yao-Lee model, supplemented by various kinds of SO(3)-symmetry-breaking terms, preserving the solvability of the model. The parent mode…
