Statistical delocalization in the Anyonic Aubry-André model
Andoni Agirre, André Eckardt, Tobias Grass
Many-body localization is remarkable in that localization persists despite the presence of dynamical interactions. Here we demonstrate the converse phenomenon: enhanced many-body d…
Anomalous fluctuations of Bose-Einstein condensates in optical lattices
Zahra Jalali-Mola, Niklas Käming, Luca Asteria +6
Fluctuations are fundamental in physics and important for understanding and characterizing phase transitions. In this spirit, the phase transition to the Bose-Einstein condensate (…
Contemporary tensor network approaches to gapless and topological phases in an extended Bose-Hubbard ladder
Yuma Watanabe, Ravindra W. Chhajlany, Maciej Lewenstein +2
The development of numerically efficient computational methods has facilitated in depth studies of various correlated phases of matter including critical and topological phases. A…
Bose-Einstein condensation in exotic lattice geometries
Kamil Dutkiewicz, Marcin Płodzień, Abel Rojo-Francàs +3
Modern quantum engineering techniques allow for synthesizing quantum systems in exotic lattice geometries, from self-similar fractal networks to negatively curved hyperbolic graphs…
Competing order in two-band Bose-Hubbard chains with extended-range interactions
Yuma Watanabe, Utso Bhattacharya, Ravindra W. Chhajlany +3
Motivated by the recent progress in realizing and controlling extended Bose-Hubbard systems using excitonic or atomic devices, the present Letter theoretically investigates the cas…
Topological Bogoliubov quasiparticles from Bose-Einstein condensate in a flat band system
Zahra Jalali-Mola, Tobias Grass, Valentin Kasper +2
For bosons with flat energy dispersion, condensation can occur in different symmetry sectors. Here, we consider bosons in a Kagome lattice with -flux hopping, which in the prese…
