Many-body effects in the excitations and dynamics of trapped Bose-Einstein condensates
Ofir E. Alon, Raphael Beinke, Lorenz S. Cederbaum
This review explores the dynamics and the low-energy excitation spectra of Bose-Einstein condensates (BECs) of interacting bosons in external potential traps putting particular emp…
Enhanced many-body effects in the excitation spectrum of a weakly-interacting rotating Bose-Einstein condensate
Raphael Beinke, Lorenz S. Cederbaum, Ofir E. Alon
The excitation spectrum of a highly-condensed two-dimensional trapped Bose-Einstein condensate (BEC) is investigated within the rotating frame of reference. The rotation is used to…
Variance of an anisotropic Bose-Einstein condensate
Shachar Klaiman, Raphael Beinke, Lorenz S. Cederbaum +2
The anisotropy of a trap potential can impact the density and variance of a Bose-Einstein condensate (BEC) in an opposite manner. We exemplify this effect for both the ground state…
Many-body effects in the excitation spectrum of weakly-interacting Bose-Einstein condensates in one-dimensional optical lattices
Raphael Beinke, Shachar Klaiman, Lorenz S. Cederbaum +2
In this work, we study many-body excitations of Bose-Einstein condensates (BECs) trapped in periodic one-dimensional optical lattices. In particular, we investigate the impact of q…
Many-body tunneling dynamics of Bose-Einstein condensates and vortex states in two spatial dimensions
Raphael Beinke, Shachar Klaiman, Lorenz S. Cederbaum +2
In this work, we study the out-of-equilibrium many-body tunneling dynamics of a Bose-Einstein condensate in a two-dimensional radial double well. We investigate the impact of inter…
