Metal-insulator transition in infinitesimally weakly disordered flatbands
Tilen Cadez, Yeongjun Kim, Alexei Andreanov +1
We study the effect of infinitesimal onsite disorder on d-dimensional all bands flat lattices. The lattices are generated from diagonal Hamiltonians by a sequence of (d + 1) local…
Heat percolation in many-body flatband localizing systems
I. Vakulchyk, C. Danieli, Alexei Andreanov +1
Translationally invariant finetuned single-particle lattice Hamiltonians host flat bands only. Suitable short-range many-body interactions result in complete suppression of particl…
Compact breathers generator in one-dimensional nonlinear networks
Carlo Danieli, Alexei Andreanov
Nonlinear networks can host spatially compact time periodic solutions called compact breathers. Such solutions can exist accidentally (i.e. for specific nonlinear strength values)…
Many-body localization transition from flatband fine-tuning
Carlo Danieli, Alexei Andreanov, Sergej Flach
Translationally invariant flatband Hamiltonians with interactions lead to a many-body localization transition. Our models are obtained from single particle lattices hosting a mix o…
Flatband generator in two dimensions
Wulayimu Maimaiti, Alexei Andreanov, Sergej Flach
Dispersionless bands -- \emph{flatbands} -- provide an excellent testbed for novel physical phases due to the fine-tuned character of flatband tight-binding Hamiltonians. The accom…
