Entropy-Driven Phase Transitions of Entanglement    [PDF]

Paolo Facchi, Giuseppe Florio, Giorgio Parisi, Saverio Pascazio, Kazuya Yuasa
We study the behavior of bipartite entanglement at fixed von Neumann entropy. We look at the distribution of the entanglement spectrum, that is the eigenvalues of the reduced density matrix of a quantum system in a pure state. We report the presence of two continuous phase transitions, characterized by different entanglement spectra, which are deformations of classical eigenvalue distributions.
