Non-Hermitian Floquet topological phases: Exceptional points, coalescent edge modes, and the skin effect

X Zhang, J Gong - Physical Review B, 2020 - APS
Periodically driven non-Hermitian systems can exhibit rich topological band structure and
non-Hermitian skin effect, without analogs in their static or Hermitian counterparts. In this …

Floquet Majorana fermions and parafermions in driven Rashba nanowires

M Thakurathi, D Loss, J Klinovaja - Physical Review B, 2017 - APS
We study a periodically driven nanowire with Rashba-like conduction and valence bands in
the presence of a magnetic field. We identify topological regimes in which the noninteracting …

Floquet topological order in interacting systems of bosons and fermions

F Harper, R Roy - Physical Review Letters, 2017 - APS
Periodically driven noninteracting systems may exhibit anomalous chiral edge modes,
despite hosting bands with trivial topology. We find that these drives have surprising many …

Topological characterization and stability of Floquet Majorana modes in Rashba nanowires

D Mondal, AK Ghosh, T Nag, A Saha - Physical Review B, 2023 - APS
We theoretically investigate a practically realizable Floquet topological superconductor
model based on a one-dimensional Rashba nanowire and proximity-induced s-wave …

Integrable many-body quantum Floquet-Thouless pumps

AJ Friedman, S Gopalakrishnan, R Vasseur - Physical review letters, 2019 - APS
We construct an interacting integrable Floquet model featuring quasiparticle excitations with
topologically nontrivial chiral dispersion. This model is a fully quantum generalization of an …

Floquet second-order topological Anderson insulator hosting corner localized modes

AK Ghosh, T Nag, A Saha - Physical Review B, 2024 - APS
The presence of random disorder in a metallic system accounts for the localization of
extended states in general. On the contrary, the presence of disorder can induce topological …

Floquet quantum criticality

W Berdanier, M Kolodrubetz… - Proceedings of the …, 2018 - National Acad Sciences
We study transitions between distinct phases of one-dimensional periodically driven
(Floquet) systems. We argue that these are generically controlled by infinite-randomness …

Emergent Weyl nodes and Fermi arcs in a Floquet Weyl semimetal

L Bucciantini, S Roy, S Kitamura, T Oka - Physical Review B, 2017 - APS
When a Dirac semimetal is subject to a circularly polarized laser, it is predicted that the Dirac
cone splits into two Weyl nodes and a nonequilibrium transient state called the Floquet Weyl …

Disorder-induced Majorana zero modes in a dimerized Kitaev superconductor chain

CB Hua, R Chen, DH Xu, B Zhou - Physical Review B, 2019 - APS
Motivated by the recent experimental observation of the topological Anderson insulator in
disordered atomic wires based on the Su-Schrieffer-Heeger (SSH) model, we study disorder …

Floquet topological insulator phase in a Weyl semimetal thin film with disorder

R Chen, DH Xu, B Zhou - Physical Review B, 2018 - APS
We investigate the effects of periodic fields and disorder on topological properties of a Weyl-
semimetal thin film. The two periodic fields, ie, a periodic magnetic field and elliptically …
