   Abstract : In the last decades, Bose-Einstein Condensates (BECs) have been a research topic of great interest. In 2015, a new type of liquid was found - dilute self-bound BEC droplets that have orders of magnitude lower density than air. These droplets are not predicted by classical van der Waals theory, but are stabilised by quantum fluctuations. READ MORE

3. 2. Real-time stability and dynamics of vortices in quasi-two-dimensional self-bound two-component Bose-Einstein condensate

   University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

   Author : Philipp Stürmer; [2019]
   Keywords : Bose-Einstein condensate; bosons; self-bound; cold atom gases; vortex; Physics and Astronomy;

   Abstract : This thesis presents a numerical study of the beyond mean field extended Gross-Pitaevskii equation for a two-component self-bound Bose-Einstein condensate, supplemented by analytical work. We extend the quasi-two-dimensional system's mean field particle-particle contact interaction by quantum fluctuations (LHY-correction). READ MORE
