Periodically and aperiodically Thue-Morse driven long-range systems: from dynamical localization to slow dynamics
Vatsana Tiwari, Devendra Singh Bhakuni, Auditya Sharma
We investigate the electric-field driven power-law random banded matrix(PLRBM) model where a variation in the power-law exponent yields a delocalization-to-localization phase t…
Diagnosing quantum transport from wave function snapshots
Devendra Singh Bhakuni, Roberto Verdel, Cristiano Muzzi +3
We study nonequilibrium quantum dynamics of spin chains by employing principal component analysis (PCA) on data sets of wave function snapshots and examine how information propagat…
Dynamic scaling relation in quantum many-body systems
Devendra Singh Bhakuni, Yevgeny Bar Lev
In delocalized systems, particle number fluctuations, also known as quantum surface roughness, and the mean-square displacement exhibit a temporal power-law growth followed by a sa…
Noise-induced transport in the Aubry-André-Harper model
Devendra Singh Bhakuni, Talía L. M. Lezama, Yevgeny Bar Lev
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 loc…
Dynamical localization and slow dynamics in quasiperiodically-driven quantum systems
Vatsana Tiwari, Devendra Singh Bhakuni, Auditya Sharma
We investigate the role of a quasiperiodically driven electric field in a one-dimensional disordered fermionic chain. In the clean non-interacting case, we show the emergence of dy…
Noise-induced dynamical localization and delocalization
Vatsana Tiwari, Devendra Singh Bhakuni, Auditya Sharma
We investigate the effect of a two-level jump process or random telegraph noise on a square wave driven tight-binding lattice. In the absence of the noise, the system is known to e…
Suppression of heating by long-range interactions in periodically driven spin chains
Devendra Singh Bhakuni, Lea F. Santos, Yevgeny Bar Lev
We propose a mechanism to suppress heating in periodically driven many-body quantum systems by employing sufficiently long-range interactions and experimentally relevant initial co…
Stability of electric-field-driven MBL in an interacting long range hopping model
Devendra Singh Bhakuni, Auditya Sharma
We study the fate of many-body localization (MBL) in the presence of long-range hopping () in a system subjected to an electric field (static and time-periodic) along w…
Drive-induced many-body localization and coherent destruction of Stark many-body localization
Devendra Singh Bhakuni, Ritu Nehra, Auditya Sharma
We study the phenomenon of many-body localization (MBL) in an interacting system subjected to a combined DC as well as a square wave AC electric field. First, the condition for the…
Entanglement and thermodynamic entropy in a clean many-body-localized system
Devendra Singh Bhakuni, Auditya Sharma
Whether or not the thermodynamic entropy is equal to the entanglement entropy of an eigenstate, is of fundamental interest, and is closely related to the `Eigenstate thermalization…
`Muhammad Ali effect' and incoherent destruction of Wannier-Stark localization in a stochastic field
Devendra Singh Bhakuni, Sushanta Dattagupta, Auditya Sharma
We calculate an exact expression for the probability propagator for a noisy electric field driven tight-binding lattice. The noise considered is a two-level jump process or a teleg…
