Driven quantum many-body systems and out-of-equilibrium topology
In this review we present some of the work done in India in the area of driven and out-of-
equilibrium systems with topological phases. After presenting some well-known examples of …

Majorana wave-function oscillations, fermion parity switches, and disorder in Kitaev chains
SS Hegde, S Vishveshwara - Physical Review B, 2016 - APS
We study the decay and oscillations of Majorana fermion wave functions and ground-state

Majorana zero modes in Y-shape interacting Kitaev wires
Motivated by the recent experimental realization of minimal Kitaev chains using quantum
dots, we investigate the Majorana zero modes (MZM) in Y-shape Kitaev wires. We solve the …
