Speaker: Shivaji Sondhi, Princeton University
Subject: Two variations on the theme of operator spreading

Operator spreading refers to the growth of local operators in spatial support and complexity under unitary dynamics. I will discuss some exact results on operator spreading under local random unitary circuits, how they tie into more general beliefs about how operators spread in different settings, and finally how these beliefs constrain the phase space for finding examples of time translation symmetry breaking.
