Driven quantum many-body systems and out-of-equilibrium topology

S Bandyopadhyay, S Bhattacharjee… - Journal of Physics …, 2021 - iopscience.iop.org
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
(GS) fermion parity in one-dimensional topological superconducting lattice systems. Using a …

Majorana zero modes in Y-shape interacting Kitaev wires

B Pandey, N Kaushal, G Alvarez, E Dagotto - npj Quantum Materials, 2023 - nature.com
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 …

Multilocational Majorana zero modes

Y Nagae, AP Schnyder, Y Tanaka, Y Asano, S Ikegaya - Physical Review B, 2024 - APS
We show the appearance of an unconventional Majorana zero mode whose wave function
splits into multiple parts located at different ends of different one-dimensional topological …

Transport signatures of bulk topological phases in double Rashba nanowires probed by spin-polarized STM

M Thakurathi, D Chevallier, D Loss, J Klinovaja - Physical Review Research, 2020 - APS
We study a double-nanowire setup proximity coupled to an s-wave superconductor and
search for the bulk signatures of the topological phase transition that can be observed …

Interaction-driven Floquet engineering of topological superconductivity in Rashba nanowires

M Thakurathi, PP Aseev, D Loss, J Klinovaja - Physical Review Research, 2020 - APS
We analyze, analytically and numerically, a periodically driven Rashba nanowire proximity
coupled to an s-wave superconductor using bosonization and renormalization group …

Extended Majorana zero modes in a topological superconducting-normal T-junction

C Spånslätt, E Ardonne - Journal of Physics: Condensed Matter, 2017 - iopscience.iop.org
We investigate the sub gap properties of a three terminal Josephson T-junction composed of
topologically superconducting wires connected by a normal metal region. This system …
