Random Bures mixed states and the distribution of their purity (2009)
Osipov, Vladimir Al., Sommers, Hans-Juergen, Zyczkowski, Karol
Ensembles of random density matrices determined by various probability measures are analysed. A simple and efficient algorithm to generate at random density matrices distributed according to the...
Statistics of thermal to shot noise crossover in chaotic cavities (2009)
Osipov, Vladimir Al., Kanzieper, Eugene
Integrable theory of noise power fluctuations in chaotic cavities with broken time-reversal symmetry is formulated. Concentrating on the universal transport regime, we determine dependence of the...
Integrable theory of quantum transport in chaotic cavities (2008)
Osipov, Vladimir Al., Kanzieper, Eugene
The problem of quantum transport in chaotic cavities with broken time-reversal symmetry is shown to be completely integrable in the universal limit. This observation is utilised to determine the...
Are Bosonic Replicas Faulty? (2007)
Osipov, Vladimir Al., Kanzieper, Eugene
Motivated by the ongoing discussion about a seeming asymmetry in the performance of fermionic and bosonic replicas, we present an exact, nonperturbative approach to zero-dimensional replica field...
