Quantum gravity in a finite box

This event is part of the HET Seminar Series.

The Wilsonian paradigm suggests universality of quantum field theory in the infrared. Interestingly, it also suggests universality of quantum mechanics (d=1 quantum field theory) in the ultraviolet. What, then, lies in the landscape of the infrared of quantum mechanics, and what are the ways in which the ultraviolet can be modified? I will focus on a particular deformation of quantum mechanics inspired by the T-Tbar deformation of two-dimensional quantum field theory. In the context of holography, this deformation will correspond to placing Jackiw-Teitelboim gravity in a finite box. I will also present an equivalent description of this deformation in terms of coupling to worldline gravity.
