Comment on "Observation of Bose-Einstein Condensation of Molecules", cond-mat/0311617
M. Wouters, J. Tempere, J. T. Devreese
In this comment, we argue that the recent experiment of Ketterle and co-workers does not necessarily need to be interpreted as indicating that the true scattering amplitude between…
Path integral formulation of the tunneling dynamics of a superfluid Fermi gas in an optical potential
M. Wouters, J. Tempere, J. T. Devreese
To describe the tunneling dynamics of a stack of two-dimensional fermionic superfluids in an optical potential, we derive an effective action functional from a path integral treatm…
Feshbach resonances in a quasi-2D atomic gas
M. Wouters, J. Tempere, J. T. Devreese
Strongly confining an ultracold atomic gas in one direction to create a quasi-2D system alters the scattering properties of this gas. We investigate the effects of confinement on F…
Resonant dynamics in boson-fermion mixtures
M. Wouters, J. Tempere, J. T. Devreese
The time evolution of a dilute atomic boson-fermion mixture is studied at zero temperature, when the external magnetic field is brought close to a interspecies Feshbach resonance.…
Three-Fluid Description of the Sympathetic Cooling of a Boson-Fermion Mixture
M. Wouters, J. Tempere, J. T. Devreese
We present a model for sympathetic cooling of a mixture of fermionic and bosonic atomic gases in harmonic traps, based on a three-fluid description. The model confirms the experime…
Fission of multielectron bubbles in liquid helium
J. Tempere, I. F. Silvera, J. T. Devreese
The stability of multielectron bubbles (MEBs) in liquid helium is investigated using the liquid-drop model for fissioning nuclei. Whereas a critical positive pressure can make the…
On the Spherical Two-Dimensional Electron Gas
J. Tempere, I. F. Silvera, J. T. Devreese
We investigate the many-body properties of a two-dimensional electron gas constrained to the surface of a sphere, a system which is physically realized in multielectron bubbles in…
The effect of pressure on statics, dynamics and stability of multielectron bubbles
J. Tempere, Isaac F. Silvera, J. T. Devreese
The effect of pressure and negative pressure on the modes of oscillation of a multi-electron bubble in liquid helium is calculated. Already at low pressures of the order of 10-100…
Many Body Diffusion and Interacting Electrons in a Harmonic Confinement
F. Luczak, F. Brosens, J. T. Devreese +1
We present numerically exact energy estimates for two-dimensional electrons in a parabolic confinement. By application of an extension of the recently introduced many-body diffusio…
Condensation and interaction range in harmonic boson traps: a variational approach
J. Tempere, F. Brosens, L. F. Lemmens +1
For a gas of N bosons interacting through a two-body Morse potential a variational bound of the free energy of a confined system is obtained. The calculation method is based on the…
Large Bipolaron in a Polaron-Gas Background
M. A. Smondyrev, A. A. Shanenko, J. T. Devreese
A criterion, proposed by the present authors, is used to derive numerical results for the stability of a large bipolaron embedded in a polaron gas. The main conclusion is that an i…
Rotational properties of trapped bosons
F. Brosens, J. T. Devreese, L. F. Lemmens
Based on the Hellman-Feynman theorem it is shown that the average square radius of a cloud of interacting bosons in a parabolic well can be derived from their free energy. As an ap…
Thermodynamics of Coupled Identical Oscillators within the Path Integral Formalism
F. Brosens, J. T. Devreese, L. F. Lemmens
A generalization of symmetrized density matrices in combination with the technique of generating functions allows to calculate the partition function of identical particles in a pa…
