Counting statistics of interfering Bose-Einstein condensates
A. L. Shelankov, J. Rammer
A method is presented that is able to predict the probability of outcomes of snapshot measurements, such as the images of the instantaneous particle density distribution in a quant…
Effective-action approach to a trapped Bose gas
Emil Lundh, Jorgen Rammer
The effective-action formalism is applied to a gas of bosons. The equations describing the condensate and the excitations are obtained using the loop expansion for the effective ac…
Charge transfer counting statistics revisited
A. Shelankov, J. Rammer
Charge transfer statistics of quantum particles is obtained by analysing the time evolution of the many-body wave function. Exploiting properly chosen gauge transformations, we con…
The influence of the Hall force on the vortex dynamics in type II superconductors
Staffan Grundberg, Jørgen Rammer
The effect of the Hall force on the pinning of vortices in type II superconductors is considered. A field theoretic formulation of the pinning problem allows a non-perturbative tre…
Influence of typical environments on quantum processes
Ping Ao, Staffan Grundberg, Jørgen Rammer
We present the results of studying the influence of different environmental states on the coherence of quantum processes. We choose to discuss a simple model which describe two ele…
