Rapidly-rotating quantum droplets confined in a harmonic potential
S. Nikolaou, G. M. Kavoulakis, M. Ogren
We consider a "symmetric" quantum droplet in two spatial dimensions, which rotates in a harmonic potential, focusing mostly on the limit of "rapid" rotation. We examine this proble…
Rotating quantum droplets confined in an anharmonic potential
S. Nikolaou, G. M. Kavoulakis, M. Ogren
We investigate the rotational properties of quantum droplets, which form in a mixture of two Bose-Einstein condensates, in the presence of an anharmonic trapping potential. We iden…
Rotating quantum droplets confined in a harmonic potential
S. Nikolaou, G. M. Kavoulakis, M. Ogren
We investigate the rotational properties of a two-component, two-dimensional self-bound quantum droplet, which is confined in a harmonic potential and compare them with the well-kn…
Correlated quantum dynamics of graphene
F. Rousse, O. Eriksson, M. Ogren
Phase-space representations are a family of methods for dynamics of both bosonic and fermionic systems, that work by mapping the system's density matrix to a quasi-probability dens…
Excitation spectrum of a mixture of two Bose gases confined in a ring potential with interaction asymmetry
A. Roussou, J. Smyrnakis, M. Magiropoulos +5
We study the rotational properties of a two-component Bose-Einstein condensed gas of distinguishable atoms which are confined in a ring potential using both the mean-field approxim…
Dimensional reduction in Bose-Einstein condensed clouds of atoms confined in tight potentials of any geometry and any interaction strength
P. Sandin, M. Ögren, M. Gulliksson +3
Motivated by numerous experiments on Bose-Einstein condensed atoms which have been performed in tight trapping potentials of various geometries (elongated and/or toroidal/annular),…
First-principles quantum dynamics for fermions: Application to molecular dissociation
M. Ogren, K. V. Kheruntsyan, J. F. Corney
We demonstrate that the quantum dynamics of a many-body Fermi-Bose system can be simulated using a Gaussian phase-space representation method. In particular, we consider the applic…
Role of spatial inhomogeneity in dissociation of trapped molecular condensates
Magnus Ogren, K. V. Kheruntsyan
We theoretically analyze dissociation of a harmonically trapped Bose-Einstein condensate of molecular dimers and examine how the spatial inhomogeneity of the molecular condensate a…
