Light scattering for thermometry of fermionic atoms in an optical lattice
J. Ruostekoski, C. J. Foot, A. B. Deb
We propose a method for measuring the temperature of fermionic atoms in an optical lattice potential from the intensity of the scattered light in the far-field diffraction pattern.…
Pulsating and persistent vector solitons in a Bose-Einstein condensate in a lattice upon phase separation instability
Uttam Shrestha, Juha Javanainen, Janne Ruostekoski
We study numerically the outcome of the phase separation instability of a dual-species Bose-Einstein condensate in an optical lattice. When only one excitation mode is unstable a b…
Quantum dynamics of instability-induced pulsations of a Bose-Einstein condensate in an optical lattice
Uttam Shrestha, Juha Javanainen, Janne Ruostekoski
We study the dynamics of a Bose-Einstein condensate in a one-dimensional optical lattice in the limit of weak atom-atom interactions, including an approximate model for quantum flu…
Nonlinear resonances in δ-kicked Bose-Einstein Condensates
T. S. Monteiro, A Rancon, J. Ruostekoski
We investigate the Quantum Resonance (QR) regime of a periodically kicked atomic Bose-Einstein condensate. We find that the clearest indicator of the nonlinear dynamics is a surpri…
