Competing delocalisation and localisation induced by the dipolar tail in fragmented lattice gases
Sabhyata Gupta, Adith Sai Aramthottil, Luis Santos
We investigate how the long-range tail of dipole-dipole interactions modifies the dynamics of strongly interacting hard-core bosons in a one-dimensional lattice. In the nearest-nei…
Interplay of localization and topology in disordered dimerized array of Rydberg atoms
Maksym Prodius, Adith Sai Aramthottil, Jakub Zakrzewski
Rydberg tweezer arrays provide a platform for realizing spin-1/2 Hamiltonians with long-range tunneling that decays as a power law with distance. We numerically investigate the eff…
Many-body localization crossover is sharper in quasiperiodic spin chains
Pedro R. Nicácio Falcão, Adith Sai Aramthottil, Piotr Sierant +1
Due to a phenomenon of many-body localization (MBL), the strong disorder may significantly slow down or even completely hinder the thermalization of quantum many-body systems. A su…
Phenomenology of many-body localization in bond-disordered spin chains
Adith Sai Aramthottil, Piotr Sierant, Maciej Lewenstein +1
Many-body localization (MBL) hinders the thermalization of quantum many-body systems in the presence of strong disorder. In this work, we study the MBL regime in bond-disordered sp…
The role of interaction-induced tunneling in the dynamics of polar lattice bosons
Adith Sai Aramthottil, Mateusz Łącki, Luis Santos +1
Inter-site dipolar interactions induce, even in absence of disorder, an intriguing non-ergodic dynamics for dipolar bosons in an optical lattice. We show that the inherent dipole-i…
Scar States in Deconfined Lattice Gauge Theories
Adith Sai Aramthottil, Utso Bhattacharya, Daniel González-Cuadra +3
The weak ergodicity breaking induced by quantum many-body scars (QMBS) represents an intriguing concept that has received great attention in recent years due to its relation to unu…
Finite-Size scaling analysis of many-body localization transition in quasi-periodic spin chains
Adith Sai Aramthottil, Titas Chanda, Piotr Sierant +1
We analyze the finite-size scaling of the average gap-ratio and the entanglement entropy across the many-body localization (MBL) transition in one dimensional Heisenberg spin-chain…
Scrambling under quench
Adith Sai Aramthottil, Diptarka Das, Suchetan Das +1
We evaluate out of time ordered correlators in certain low dimensional quantum systems at zero temperature, subjected to homogenous quantum quenches. We find that when the Lyapunov…
