Topological invariants of Floquet systems: General formulation, special properties, and Floquet topological defects

S Yao, Z Yan, Z Wang - Physical Review B, 2017 - APS
Periodically driven (Floquet) systems have been under active theoretical and experimental
investigations. This paper aims at a systematic study in the following aspects of Floquet …

Non-Hermitian Floquet topological superconductors with multiple Majorana edge modes

L Zhou - Physical Review B, 2020 - APS
Majorana edge modes are candidate elements of topological quantum computing. In this
paper, we propose a Floquet engineering approach to generate multiple non-Hermitian …

Monitoring Electron-Photon Dressing in WSe2

U De Giovannini, H Hubener, A Rubio - Nano letters, 2016 - ACS Publications
Optical pumping of solids creates a nonequilibrium electronic structure where electrons and
photons combine to form quasiparticles of dressed electronic states. The resulting shift of …

Controlling quantum transport via dissipation engineering

F Damanet, E Mascarenhas, D Pekker, AJ Daley - Physical Review Letters, 2019 - APS
Inspired by the microscopic control over dissipative processes in quantum optics and cold
atoms, we develop an open-system framework to study dissipative control of transport in …

Photon-inhibited topological transport in quantum well heterostructures

A Farrell, T Pereg-Barnea - Physical Review Letters, 2015 - APS
Here we provide a picture of transport in quantum well heterostructures with a periodic
driving field in terms of a probabilistic occupation of the topologically protected edge states …

Edge-state transport in Floquet topological insulators

A Farrell, T Pereg-Barnea - Physical Review B, 2016 - APS
Floquet topological insulators are systems in which the topology emerges only when a time-
periodic perturbation is applied. In these systems one can define quasienergy states which …

All-optical scheme for detecting the possible Majorana signature based on QD and nanomechanical resonator systems

HJ Chen, KD Zhu - Science China Physics, Mechanics & Astronomy, 2015 - Springer
Majorana fermions (MFs) are exotic particles that are their own anti-particles. Currently, the
search for MFs occurring as quasiparticle excitations in condensed matter systems has …

Some exact properties of the nonequilibrium response function for transient photoabsorption

E Perfetto, G Stefanucci - Physical Review A, 2015 - APS
The physical interpretation of time-resolved photoabsorption experiments is not as
straightforward as for the more conventional photoabsorption experiments conducted on …

Stability of Floquet Majorana box qubits

A Matthies, J Park, E Berg, A Rosch - Physical review letters, 2022 - APS
In one-dimensional topological superconductors driven periodically with the frequency ω,
two types of topological edge modes may appear, the well-known Majorana zero mode and …

Brillouin-Wigner theory for Floquet topological phase transitions in spin-orbit-coupled materials

P Mohan, R Saxena, A Kundu, S Rao - Physical Review B, 2016 - APS
We develop the high-frequency expansion based on the Brillouin-Wigner (BW) perturbation
theory for driven systems with spin-orbit coupling which is applicable to the cases of silicene …
