Bose-Einstein condensation of 2D dipolar excitons: Quantum Monte Carlo simulation
Yu. E. Lozovik, I. L. Kurbakov, G. E. Astrakharchik +1
The Bose condensation of 2D dipolar excitons in quantum wells is numerically studied by the diffusion Monte Carlo simulation method. The correlation, microscopic, thermodynamic, an…
Two-dimensional weakly interacting Bose gas: equation of state
G. E. Astrakharchik, J. Boronat, J. Casulleras +2
The equation of state of a weakly interacting two-dimensional Bose gas is studied at zero temperature by means of quantum Monte Carlo methods. Going down to as low densities as na^…
Superfluidity of two- dimensional excitons in flat and harmonic traps
Yu. E. Lozovik, I. L. Kurbakov, M. Willander
Superfluid exciton density and superfluid transition (crossover) temperature are calculated for 2D excitons in large-size flat and harmonic traps. A generalized local density appro…
Effects of strong correlations for 2D Bose-Einstein condensed dipolar excitons
Yu. E. Lozovik, I. L. Kurbakov, G. E. Astrakharchik +2
By doing quantum Monte Carlo ab initio simulations we show that dipolar excitons, which are now under experimental study, actually are strongly correlated systems. Strong correlati…
Weakly interacting two-dimensional system of dipoles: limitations of mean-field theory
G. E. Astrakharchik, J. Boronat, J. Casulleras +2
We consider a homogeneous 2D Bose gas with repulsive dipole-dipole interactions. The ground-state equation of state, calculated using the Diffusion Monte Carlo method, shows quanti…
Quantum phase transition in a two-dimensional system of dipoles
G. E. Astrakharchik, J. Boronat, I. L. Kurbakov +1
The ground-state phase diagram of a two-dimensional Bose system with dipole-dipole interactions is studied by means of quantum Monte Carlo technique. Our calculation predicts a qua…
