Efficient auxiliary-mode approach for time-dependent nanoelectronics

BS Popescu, A Croy - New Journal of Physics, 2016 - iopscience.iop.org
A new scheme for numerically solving the equations arising in the time-dependent non-
equilibrium Green's function formalism is developed. It is based on an auxiliary-mode …

One-way transport in laser-illuminated bilayer graphene: A Floquet isolator

V Dal Lago, E Suárez Morell, LEF Foa Torres - Physical Review B, 2017 - APS
We explore the Floquet band structure and electronic transport in laser-illuminated bilayer
graphene ribbons. By using a bias voltage perpendicular to the graphene bilayer we show …

Topological insulator in the presence of spatially correlated disorder

A Girschik, F Libisch, S Rotter - Physical Review B—Condensed Matter and …, 2013 - APS
We investigate the effect of spatially correlated disorder on two-dimensional topological
insulators and on the quantum spin Hall effect which the helical edge states in these …

Time-dependent thermoelectric transport for nanoscale thermal machines

AM Daré, P Lombardo - Physical Review B, 2016 - APS
We analyze an electronic nanoscale thermal machine driven by time-dependent
environment: besides bias and gate voltage variations, we consider also the less prevailing …

Time-dependent resonant tunneling transport: Keldysh and Kadanoff-Baym nonequilibrium Green's functions in an analytically soluble problem

MM Odashima, CH Lewenkopf - Physical Review B, 2017 - APS
Here we address two nonequilibrium Green's-function approaches for a resonant tunneling
structure under a sudden switch of a bias. Our aim is to stress that the time-dependent …

Renormalization in periodically driven quantum dots

AK Eissing, V Meden, DM Kennes - Physical Review Letters, 2016 - APS
We report on strong renormalization encountered in periodically driven interacting quantum
dots in the nonadiabatic regime. Correlations between lead and dot electrons enhance or …

Transient dynamics of a quantum dot embedded between two superconducting leads and a metallic reservoir

R Taranko, T Kwapiński, T Domański - Physical Review B, 2019 - APS
We study time-dependent subgap properties of a quantum dot (QD) embedded between two
superconductors and another metallic lead, solving the Heisenberg equations of motion by …

Functional renormalization group in Floquet space

AK Eissing, V Meden, DM Kennes - Physical Review B, 2016 - APS
We present an extension of the functional renormalization group to Floquet space, which
enables us to treat the long time behavior of interacting time periodically driven quantum …

Emergence of Larkin-Ovchinnikov-type superconducting state in a voltage-driven superconductor

T Kawamura, Y Ohashi, HTC Stoof - Physical Review B, 2024 - APS
We theoretically investigate a voltage-biased normal metal–superconductor–normal metal
(NSN) junction. Using the nonequilibrium Green's function technique, we derive a quantum …

Treatment of time‐dependent effects in molecular junctions

B Popescu, U Kleinekathöfer - physica status solidi (b), 2013 - Wiley Online Library
The current through molecular junctions can be influenced by various time‐dependent
perturbations. Among these are external (laser) fields and fluctuating environments. Both …
