Poisson Statistics in the High Temperature QCD Dirac Spectrum
Poisson Statistics High Temperature QCD Dirac Spectrum
2011/1/14
At low temperature in the epsilon regime of QCD the low-end of the Dirac spectrum is described
by random matrix theory. In contrast, there has been no similarly well established staistical descriptio...
Power-law ensembles: fluctuations of volume or temperature ?
Power-law ensembles fluctuations of volume temperature
2011/1/10
We present two issues here: (i) that in situation when total energy is kept constant re-cently proposed fluctuations of volume ensemble is equivalent to the approach using Tsallis statistics with fluc...
