Degenerate Quantum Gases and Bose-Einstein Condensation

Luca Salasnich

After a brief historical introduction to Bose-Einstein condensation and Fermi degeneracy, we discuss theoretical results we have recentely obtained for trapped degenerate quantum gases by means of a thermal field theory approach. In particular, by using Gross-Pitaevskii and Bogoliubov-Popov equations, we consider thermodynamical properties of two Bosonic systems: a gas of Lithium atoms and a gas of Hydrogen atoms. Finally, we investigate finite-temperature density profiles of a dilute Fermi gas of Potassium atoms confined in a harmonic potential.

Unified way for computing dynamics of Bose–Einstein condensates and degenerate Fermi gases

Krzysztof Gawryluk, Tomasz Karpiuk, Mariusz Gajda +2 more

In this work we present a very simple and efficient numerical scheme which can be applied to study the dynamics of bosonic systems like, for instance, spinor Bose–Einstein condensates (BEC) with non-local interactions but equally well works for Fermi gases. The method we use is a modification of well known Split Operator Method (SOM). We carefully examine this algorithm in the case of F=1 spinor BEC without and with dipolar interactions and for strongly interacting two-component Fermi gas. Our extension of the SOM method has many advantages: it is fast, stable, and keeps constant all the physical constraints (constants of motion) at high level.

Recent Experiments with Ultracold Quantum-Degenerate Atomic Gases

Dominik Schneble

This article reviews some recent experiments with ultracold quantum-degenerate atomic gases at MIT that were presented at the 35th EGAS Conference, including studies of a degenerate strongly interacting Fermi gas, the collective scattering of light from a Bose–Einstein condensate, and the manipulation of condensates in microstructured magnetic potentials.
