Finite-temperature spin diffusion in the two-dimensional XY model
Erik Fitzner, Byungjin Lee, Junhyeok Hur +4
We present a combined theory-experiment study to quantify spin diffusion in the square lattice quantum spin-1/2 XY model at finite temperature. On the theory side, we leverage a re…
Thermal liquid-gas phase transition in a quasi-one-dimensional dipolar Fermi gas
Lanxuan Gao, Koki Takayama, Hiroyuki Tajima +2
We theoretically investigate the thermodynamic properties of a quasi-one-dimensional single-component dipolar Fermi gas at finite temperatures. A self-bound fermionic droplet can b…
On the fluctuations of the number of atoms in the condensate
Maciej B. Kruk, Piotr Kulik, Malthe F. Andersen +6
Bose-Einstein condensation represents a remarkable phase transition, characterized by the formation of a single quantum subsystem. As a result, the statistical properties of the co…
One-Dimensional Quench Dynamics in an Optical Lattice: sine-Gordon and Bose-Hubbard Descriptions
Subhrajyoti Roy, Rhombik Roy, Andrea Trombettoni +2
We investigate the dynamics of one-dimensional interacting bosons in an optical lattice after a sudden quench in the Bose-Hubbard (BH) and sine-Gordon (SG) regimes. While in higher…
Diminished quantum depletion and correlated droplets in one-dimensional dipolar Bose gas
B. Tüzemen, M. Marciniak, K. Pawłowski
We investigate the formation of self-bound states in a one-dimensional dipolar Bose gas under the influence of both strong short-range repulsive and strong non-local attractive int…
Properties of a trapped multiple-species bosonic mixture at the infinite-particle-number limit: A solvable model
O. E. Alon, L. S. Cederbaum
We investigate a trapped mixture of Bose-Einstein condensates consisting of a multiple number of P species using an exactly-solvable many-body model, the -species harmonic-inter…
