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…
Spectral Magnetization Ratchets with Discrete Time Quantum Walks
A. Mallick, M. V. Fistul, P. Kaczynska +1
We predict and theoretically study in detail the ratchet effect for the spectral magnetization of periodic discrete time quantum walks (DTQWs) --- a repetition of a sequence of …
