Approaching the scaling limit of transport through lattices with dephasing
Subhajit Sarkar, Gabriela Wójtowicz, Bartłomiej Gardas +2
We examine the stationary--state equations for lattices with generalized Markovian dephasing and relaxation. When the Hamiltonian is quadratic, the single--particle correlation mat…
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…
Classifying Measurement Incompatibility under Classical Pre- and Post-Processing Operations
Arun Kumar Das, Saheli Mukherjee, Debashis Saha +2
Measurement incompatibility has proved to be an important resource for quantum information processing. In this work, we present an operational approach that leverages classical ope…
Refractive index profiles for a -symmetric optical structure
Bijan Bagchi, Rahul Ghosh, Sauvik Sen
By mapping the scalar Helmholtz equation (SHE) to the Schrodinger form we investigate the behaviour of optical structure when the refractive index distribution a…
Random density matrices: Analytical results for mean fidelity and variance of squared Bures distance
Aritra Laha, Santosh Kumar
One of the key issues in quantum information theory related problems concerns with that of distinguishability of quantum states. In this context, Bures distance serves as one of th…
