Dynamics of matter-wave and optical fields in superradiant scattering from Bose-Einstein condensates
O. Zobay, Georgios M. Nikolopoulos
We study superradiant scattering off Bose-Einstein condensates by solving the semiclassical Maxwell-Schroedinger equations describing the coupled dynamics of matter-wave and optica…

Thermodynamics of a trapped interacting Bose gas and the renormalization group
G. Metikas, O. Zobay, G. Alber
We apply perturbative renormalization group theory to the symmetric phase of a dilute interacting Bose gas which is trapped in a three-dimensional harmonic potential. Using Wilsoni…

The epsilon-expansion in the symmetry-broken phase of an interacting Bose gas at finite temperature
G. Metikas, O. Zobay, G. Alber
We discuss the application of the momentum-shell renormalization group method to the interacting homogeneous Bose gas in the symmetric and in the symmetry-broken phases. It is demo…
