Nonequilibrium Dynamics of Optical Lattice-Loaded BEC Atoms: Beyond HFB Approximation
Ana Maria Rey, B. L. Hu, Esteban Calzetta +2
In this work a two-particle irreducible (2PI) closed-time-path (CTP) effective action is used to describe the nonequilibrium dynamics of a Bose Einstein condensate (BEC) selectivel…
Quantum Noise and Fluctuations in Gravitation and Cosmology
B. L. Hu, Albert Roura, Sukanya Sinha +1
We give a short update of our research program on nonequilibrium statistical field theory applied to quantum processes in the early universe and black holes, as well as the develop…
Activation-like processes at zero temperature
Daniel Arteaga, Esteban Calzetta, Albert Roura +1
We examine the possibility that a metastable quantum state could experiment a phenomenon similar to thermal activation but at zero temperature. In order to do that we study the rea…
