Classical phases and quantum angles in the description of interfering Bose-Einstein condensates
Condensate random variables measurements
2014/12/19
The interference of two Bose-Einstein condensates, initially in Fock states, can be described in terms of their relative phase, treated as a random unknown variable. This phase can be understood eithe...
The total many-body correlations present in nite temperature classical spin systems are studied using the concept of mutual information. As opposed to zero-temperature quantum phase transitions,the t...
Polymer quantization of the free scalar field and its classical limit
free scalar field Polymer quantization classical limit
2010/3/18
Building on prior work, a generally covariant reformulation of free scalar field theory on the flat Lorentzian cylinder is quantized using Loop Quantum Gravity (LQG) type `polymer' representations. Th...
