Old and new scaling laws in quantum quench

The response of a many-body system to a time-dependent coupling which passes through or approaches a critical point displays universal scaling behavior. In some regimes, scaling laws have been known since the 1970s. Recently, holographic techniques have been used to understand the origins of such scaling. Along the way, new scaling behaviors in other regimes have been found in holographic models, which have later been shown to hold in a generic field theory regardless of holography. This contribution summarizes recent work on these various scaling regimes.

I amgrateful to the organizers of the Nambu Symposium for inviting me to speak at this stimulating conference. This contribution is based onmywork with Pallab Basu, Diptarka Das, Damian Galante,Takeshi Morita, Robert Myers, Tatsuma Nishioka, and Krishnendu Sengupta. I thank them for a very fruitful set of collaborations. I would also like to thank Hong Liu, Gautam Mandal, Al Shapere, Steve Shenker, Eva Silverstein, Shibaji Sondhi, Lenny Susskind, and Tadashi Takayanagi for discussions. I have also benefited from conversations with the participants of the NORDITA workshop on Holography and Dualities 2016, and theYukawa Institute for Theoretical Physics workshop on Quantum Information in String Theory and Many Body Systems, where parts of the work were presented. I would like to thank the organizers of these workshops for their hospitality. This work was supported in part by National Science Foundation grants NSF-PHY-1214341 and NSF-PHY- 1521045.
