 +nonlocality, and other quantum correlations (such as quantum discord) 
 +in multi-particle quantum systems. Topics of interest include quantum 
 +phase transitions in condensed matter systems, characterization of 
 +quantum protocols through the collective correlation behavior, 
 +thermalization of pure quantum states, and quantum thermodynamics. \\
