Guidelines for designs for ultrastable laser with fractional frequency instability
Joannès Barbarat, Erik Benkler, Marcin Bober +46
Lasers with long coherence time and narrow linewidth are an essential tool for quantum sensors and clocks. Ultrastable cavities and laser systems are now commercially available wit…
Stability of nonstationary states of spin-2 Bose-Einstein condensates
H. Mäkelä, E. Lundh
The dynamical stability of nonstationary states of homogeneous spin-2 rubidium Bose-Einstein condensates is studied. The states considered are such that the spin vector remains par…
Stability of nonstationary states of spin-1 Bose-Einstein condensates
H. Mäkelä, M. Johansson, M. Zelan +1
The stability of nonstationary states of homogeneous spin-1 Bose-Einstein condensates is studied by performing Bogoliubov analysis in a frame of reference where the state is statio…
Directed transport with real-time steering and drifts along pre-designed paths using a Brownian motor
H. Hagman, M. Zelan, C. M. Dion +1
We have realized real-time steering of the directed transport in a Brownian motor based on cold atoms in optical lattices, and demonstrate drifts along pre-designed paths. The tran…
Experimental measurement of efficiency and transport coherence of a cold atom Brownian motor in optical lattices
M. Zelan, H. Hagman, G. Labaigt +2
The rectification of noise into directed movement or useful energy is utilized by many different systems. The peculiar nature of the energy source and conceptual differences betwee…
One-dimensional phase transitions in a two-dimensional optical lattice
Magnus Rehn, Sara Bergkvist, Anders Rosengren +4
A phase transition for bosonic atoms in a two-dimensional anisotropic optical lattice is considered. If the tunnelling rates in two directions are different, the system can undergo…
