Impact of dephasing on non-equilibrium steady-state transport in fermionic chains with long-range hopping
Subhajit Sarkar, Bijay Kumar Agarwalla, Devendra Singh Bhakuni
Quantum transport in a non-equilibrium setting plays a fundamental role in understanding the properties of systems ranging from quantum devices to biological systems. Dephasing --…
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…
Periodically and quasiperiodically driven-anisotropic Dicke model
Pragna Das, Devendra Singh Bhakuni, Lea F. Santos +1
We analyze the anisotropic Dicke model in the presence of a periodic drive and under a quasiperiodic drive. The study of drive-induced phenomena in this experimentally accesible mo…
Phase transitions of the anisotropic Dicke model
Pragna Das, Devendra Singh Bhakuni, Auditya Sharma
We systematically analyze the various phase transitions of the anisotropic Dicke model that is endowed with both rotating and counter-rotating light-matter couplings. In addition t…
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…
