Intermediate super-exponential localization with Aubry-André chains
Arindam Mallick, Alexei Andreanov, Sergej Flach
We demonstrate the existence of an intermediate super-exponential localization regime for eigenstates of the Aubry-André chain. In this regime, the eigenstates localize factorially…
Correlated metallic two-particle bound states in Wannier--Stark flatbands
Arindam Mallick, Alexei Andreanov, Sergej Flach
Tight-binding single-particle models on simple Bravais lattices in space dimension , when exposed to commensurate DC fields, result in the complete absence of transport d…
Logarithmic expansion of many-body wave packets in random potentials
Arindam Mallick, Sergej Flach
Anderson localization confines the wave function of a quantum particle in a one-dimensional random potential to a volume of the order of the localization length . Nonlinear add-…
Wannier-Stark flatbands in Bravais lattices
Arindam Mallick, Nana Chang, Wulayimu Maimaiti +2
We systematically construct flatbands (FB) for tight-binding models on simple Bravais lattices in space dimension in the presence of a static uniform DC field. Commensur…
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…
Topological delocalization in the completely disordered two-dimensional quantum walk
János K. Asbóth, Arindam Mallick
We investigate numerically and theoretically the effect of spatial disorder on two-dimensional split-step discrete-time quantum walks with two internal "coin" states. Spatial disor…
