Quantum transport under oscillatory drive with disordered amplitude
Vatsana Tiwari, Sushanta Dattagupta, Devendra Singh Bhakuni +1
We investigate the dynamics of non-interacting particles in a one-dimensional tight-binding chain in the presence of an electric field with random amplitude drawn from a Gaussian d…
The disordered Dicke model
Pragna Das, Sebastian Wüster, Auditya Sharma
We introduce and study the disordered Dicke model in which the spin-boson couplings are drawn from a random distribution with some finite width. Regarding the quantum phase transit…
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…
Phase classification in the long-range Harper model using machine learning
Aamna Ahmed, Abee Nelson, Ankur Raina +1
In this work, we map the phase diagrams of one-dimensional quasiperiodic models using artificial neural networks. We observe that the multi-class classifier precisely distinguishes…
Interplay of many-body interactions and quasiperiodic disorder in the all-band-flat diamond chain
Aamna Ahmed, Nilanjan Roy, Auditya Sharma
We study the effects of quasiperiodic Aubry-André (AA) disorder and interactions on a one-dimensional all-band-flat (ABF) diamond chain. We consider the application of disorder in…
