Bose-Einstein Condensate of Trimers Dressed by Atom-Dimer Cooper Pairs
Matt Mackie, Jyrki Piilo, Olavi Dannenberg
We theoretically examine the neutral atom-molecule analogue of the anomalous quantum correlations between degenerate electrons, i.e., Cooper pairs, that are responsible for superco…

Decoherence in the Heisenberg model
Olavi Dannenberg
We study a simplified Heisenberg spin model in order to clarify the idea of decoherence in closed quantum systems. For this purpose, we define a new concept: the decoherence functi…
