Nonadiabatic landau–zener–stückelberg–majorana transitions, dynamics, and interference

V Ivakhnenko, SN Shevchenko, F Nori - Physics Reports, 2023 - Elsevier
Since the pioneering works by Landau, Zener, Stückelberg, and Majorana (LZSM), it has
been known that driving a quantum two-level system results in tunneling between its states …

Strong disorder RG approach–a short review of recent developments

F Iglói, C Monthus - The European Physical Journal B, 2018 - Springer
The strong disorder RG approach for random systems has been extended in many new
directions since our previous review of 2005 [F. Igloi, C. Monthus, Phys. Rep. 412, 277 …

Quantum criticality and Kibble-Zurek scaling in the Aubry-André-Stark model

EW Liang, LZ Tang, DW Zhang - Physical Review B, 2024 - APS
We explore quantum criticality and Kibble-Zurek scaling (KZS) in the Aubry-André-Stark
(AAS) model, where the Stark field of strength ɛ is added onto the one-dimensional …

Coexistence of extended and localized states in the one-dimensional non-Hermitian Anderson model

C Yuce, H Ramezani - Physical Review B, 2022 - APS
In one-dimensional Hermitian tight-binding models, mobility edges separating extended and
localized states can appear in the presence of properly engineered quasiperiodical …

Kibble-Zurek mechanism with a single particle: Dynamics of the localization-delocalization transition in the Aubry-André model

A Sinha, MM Rams, J Dziarmaga - Physical Review B, 2019 - APS
The Aubry-André one-dimensional lattice model describes a particle hop** in a
pseudorandom potential. Depending on its strength λ, all eigenstates are either localized (λ> …

Phase transitions of the anisotropic Dicke model

P Das, DS Bhakuni, A Sharma - Physical Review A, 2023 - APS
We systematically analyze the various phase transitions of the anisotropic Dicke model that
is endowed with both rotating and counterrotating light-matter couplings. In addition to the …

Signatures of many-body localization in the dynamics of two-site entanglement

F Iemini, A Russomanno, D Rossini, A Scardicchio… - Physical Review B, 2016 - APS
We are able to detect clear signatures of dephasing—a distinct trait of many-body
localization (MBL)—via the dynamics of two-site entanglement, quantified through the …

Many-body localization in infinite chains

T Enss, F Andraschko, J Sirker - Physical Review B, 2017 - APS
We investigate the phase transition between an ergodic and a many-body localized phase
in infinite anisotropic spin-1/2 Heisenberg chains with binary disorder. Starting from the Néel …

Noise-induced transport in the Aubry-André-Harper model

DS Bhakuni, T LM Lezama, Y Bar Lev - SciPost Physics Core, 2024 - scipost.org
We study quantum transport in a quasiperiodic Aubry-André-Harper (AAH) model induced
by the coupling of the system to a Markovian heat bath. We find that coupling the heat bath …

Anomalous transport in the Aubry-André-Harper model in isolated and open systems

A Purkayastha, S Sanyal, A Dhar, M Kulkarni - Physical Review B, 2018 - APS
We study the high-temperature transport behavior of the Aubry-André-Harper (AAH) model,
both in an isolated thermodynamic limit and in an open system. At the critical point of the …
