Factorization and Criticality in the Anisotropic XY Chain via Correlations

  • Barış Çakmak,
  • Göktuğ Karpat and
  • Felipe F. Fanchini

9 February 2015

In this review, we discuss the zero and finite temperature behavior of various bipartite quantum and total correlation measures, the skew information-based quantum coherence and the local quantum uncertainty in the thermal ground state of the one-dim...

Entropy Production of Main-Sequence Stars

  • Leonid M. Martyushev and
  • Sergey N. Zubarev

2 February 2015

The entropy production (inside the volume bounded by a photosphere) of main-sequence stars is calculated based on B–V photometry data. The entropy-production distribution function and the dependences of entropy production on temperature and luminosi...
