Construction-Dependent Floquet Topology in Circularly Driven -Stacked Su-Schrieffer-Heeger Chains
Aayushi Agrawal, Jayendra N. Bandyopadhyay
We investigate construction-dependent Floquet topology in a two-dimensional lattice formed by stacking Su-Schrieffer-Heeger (SSH) chains with co-located sublattice orbitals. We pre…
Floquet spintronics: tuning the current-induced spin polarization of topological surface states with light
Youngjae Kim, Aayushi Agrawal, Kwon Park
Topological surface states are a promising platform for spintronics due to spin-momentum locking. Spin-momentum locking can induce a net spin polarization in topological surface st…
Quasi-Majorana modes in the -wave Kitaev chains on a square lattice
S. Srinidhi, Aayushi Agrawal, Jayendra N. Bandyopadhyay
The topological characteristics of the -wave Kitaev chains on a square lattice with nearest-neighbor and next-nearest-neighbor inter-chains hopping and pairing are investigated.…
Laser induced Flqouet topological phases in a 2D weak topological insulator with unconventional nonlinear dispersion
Aayushi Agrawal, Jayendra N. Bandyopadhyay
Recently, we presented a two-dimensional (2D) model of a weak topological insulator formed by stacking an number of Su-Schrieffer-Heeger (SSH) chains \cite{Agrawal_2022-02}. We…
Cataloging topological phases of -stacked Su-Schrieffer-Heeger chains by a systematic breaking of symmetries
Aayushi Agrawal, Jayendra N. Bandyopadhyay
Two-dimensional (2D) model of a weak topological insulator with -stacked Su-Schrieffer-Heeger (SSH) chain is studied. This study starts with a basic model with all the fundament…
Floquet topological phases with high Chern numbers in a periodically driven extended Su-Schrieffer-Heeger model
Aayushi Agrawal, Jayendra N. Bandyopadhyay
The high Chern number phases with the Chern number |C| > 1 are observed in this study of a periodically driven extended Su-Schrieffer-Heeger (E-SSH) model with a cyclic parameter.…
