Exponentially Fragile PT-Symmetry in Lattices with Localized Eigenmodes
Oliver Bendix, Ragnar Fleischmann, Tsampikos Kottos +1
We study the effect of localized modes in lattices of size N with parity-time (PT) symmetry. Such modes are arranged in pairs of quasi-degenerate levels with splitting delta exp{-N…

Caustic formation in expanding condensates of cold atoms
J. T. Chalker, B. Shapiro
We study the evolution of density in an expanding Bose-Einstein condensate that initially has a spatially varying phase, concentrating on behaviour when these phase variations are…

Self-consistent study of Anderson localization in the Anderson-Hubbard model in two and three dimensions
Peter Henseler, Johann Kroha, Boris Shapiro
We consider the change in electron localization due to the presence of electron-electron repulsion in the \HA model. Taking into account local Mott-Hubbard physics and static scree…
