Thermalization in the one-dimensional Salerno model lattice
T. Mithun, A. Maluckov, B. M. Manda +5
The Salerno model constitutes an intriguing interpolation between the integrable Ablowitz-Ladik (AL) model and the more standard (non-integrable) discrete nonlinear Schr{ö}dinger (…
Fragile Many Body Ergodicity
Thudiyangal Mithun, Carlo Danieli, M. V. Fistul +2
Weakly nonintegrable many-body systems can restore ergodicity in distinctive ways depending on the range of the interaction network in action space. Action resonances seed chaotic…
Decay of two-dimensional quantum turbulence in binary Bose-Einstein condensates
Mithun Thudiyangal, Kenichi Kasamatsu, Bishwajyoti Dey +1
We study two-dimensional quantum turbulence in miscible binary Bose-Einstein condensates in either a harmonic trap or a steep-wall trap through the numerical simulations of the Gro…
Quench dynamics in disordered two-dimensional Gross-Pitaevskii Lattices
Arindam Mallick, Thudiyangal Mithun, Sergej Flach
We numerically investigate the quench expansion dynamics of an initially confined state in a two-dimensional Gross-Pitaevskii lattice in the presence of external disorder. The expa…
Quantum Caging in Interacting Many-Body All-Bands-Flat Lattices
Carlo Danieli, Alexei Andreanov, Thudiyangal Mithun +1
We consider translationally invariant tight-binding all-bands-flat networks which lack dispersion. In a recent work [arXiv:2004.11871] we derived the subset of these networks which…
Nonlinear caging in All-Bands-Flat Lattices
Carlo Danieli, Alexei Andreanov, Thudiyangal Mithun +1
We study the impact of classical short-range nonlinear interactions on transport in lattices with no dispersion. The single particle band structure of these lattices contains flat…
