Matrix Product States, Random Matrix Theory and the Principle of Maximum Entropy
arXiv:1201.6324 · doi:10.1007/s00220-013-1718-x
Abstract
Using random matrix techniques and the theory of Matrix Product States we show that reduced density matrices of quantum spin chains have generically maximum entropy.
