Abstract: I will describe the universal aspect of unitary conformal field theories in the high-temperature limit with a global symmetry group G, where G can be a discrete group or a compact Lie group. I will describe the geometric setup to apply the spurion analysis and explain how we can capture this universal aspect up to a constant factor that … Read More
Abstract: Detecting a Stochastic Gravitational Wave Background (SGWB) signal from cosmological phase transitions could provide insights into the early epochs of the universe. However, connecting measurements to underlying theories is challenging due to various models producing similar GW signals. In this talk, I will discuss an example of mapping UV theory to expected signals, specifically the parametric scaling of supercooled … Read More
Abstract: We discuss dilaton gravity with potentials that are deformed away from JT gravity. We discuss semi-classical solutions with these potentials and elucidate new complex saddles at fixed energy which contribute to the density of states. We also discuss how to reproduce the semi-classical limit of a formula for the density of states first derived by using the connection between … Read More
Abs: Historically tensor networks have been helpful models of AdS/CFT, but there have always been some aspects that they fail to capture, particularly those involving the time direction. In this talk I will take the perspective that we can learn a lot from trying to incorporate these aspects into tensor networks, and I will explain some progress on resolving the … Read More
