Information in statistical physics
R. Balian
We review with a tutorial scope the information theory foundations of quantum statistical physics. Only a small proportion of the variables that characterize a system at the micros…
The quantum measurement process: an exactly solvable model
A. E. Allahverdyan, R. Balian, Th. M. Nieuwenhuizen
An exactly solvable model for a quantum measurement is discussed, that integrates quantum measurements with classical measurements. The z-component of a spin-1/2 test spin is measu…
Temperature Dependence of Even-Odd Effects in Small Superconducting Systems
R. Balian, H. Flocard, M. Veneroni
Generalized BCS equations which consistently include the projection on the particle-number parity are derived from a systematic variational method. Numerical solutions are given th…
Extended BCS Theories
R. Balian, H. Flocard, M. Vénéroni
Extensions of the Hartree-Fock-Bogoliubov theory are worked out which are tailored for, (i) the consistent evaluation of fluctuations and correlations and (ii) the restoration thro…
