Realizing Bose-Einstein condensation in a Mexican-hat-like potential

23 Feb 2020 Máté Mihály Legeza Örs Schilling Rolf Yousif Mason Schilling Christian

We propose and study a model for $N$ hard-core bosons which allows for the interpolation between one- and high-dimensional behavior by variation of just a single external control parameter $s/t$. It consists of a ring-lattice of $d$ sites with a hopping rate $t$ and an extra site at its center... (read more)
