Entanglement Entropy of theν=1/2Composite Fermion Non-Fermi Liquid State
Entanglement Entropy of theν=1/2Composite Fermion Non-Fermi Liquid State
The so-called "non-Fermi liquid" behavior is very common in strongly correlated systems. However, its operational definition in terms of "what it is not" is a major obstacle for the theoretical understanding of this fascinating correlated state. Recently there has been much interest in entanglement entropy as a theoretical tool to …
