Phase diagram of bipartite entanglement
Published 4 Jun 2019 in quant-ph, math-ph, and math.MP | (1906.01269v1)
Abstract: We investigate the features of the entanglement spectrum (distribution of the eigenvalues of the reduced density matrix) of a large quantum system in a pure state. We consider all R\'enyi entropies and recover purity and von Neumann entropy as particular cases. We construct the phase diagram of the theory and unveil the presence of two critical lines.
