SUMMARY:Proper correlation measures: the case with Rényi mutual infor
 mation\, R. G. Herb Condensed Matter Seminar\, Laimei Nie\, Purdue
DESCRIPTION:Mutual information\, defined via the linear combinations o
 f von Neumann entanglement entropies\, measures the total correlations
  between two subsystems and has played a vital role in characterizing 
 equilibrium and non-equilibrium phenomena in many-body physics. In pra
 ctice\, its Renyi counterpart is usually computed owing to its simplic
 ity. However\, this commonly used notion of Renyi Mutual Information (
 RMI) cannot be interpreted as a measure of correlation\, because it is
  neither non-negative nor does it satisfy the Data Processing Inequali
 ty. In this talk\, we will explore several classes of properly defined
  RMIs. In particular\, we develop an easily implementable replica tric
 k which enables us to evaluate these RMIs in a variety of many-body sy
 stems\, including 2D conformal field theories and random tensor networ
 ks. We will also discuss the prospect of measuring these new RMIs in q
 uantum simulator experiments.
