Entanglement and localization of wavefunctions

O. Giraud, J. Martin, B. Georgeot

par Bertrand Georgeot - 24 septembre 2009

We review recent works that relate entanglement of random vectors to their localization properties. In particular, the linear entropy is related by a simple expression to the inverse participation ratio, while next orders of the entropy of entanglement contain information about e.g. the multifractal exponents. Numerical simulations show that these results can account for the entanglement present in wavefunctions of physical systems.
