Title: Quantum Gravity Signals in 4D Einstein gravity from 2D JT gravity Abstract: It is generally believed that quantum gravity fluctuations in a vacuum are immeasurably small from an effective field theory (EFT) perspective, as their size is suppressed by powers of the Planck mass. In this talk, we study quantum fluctuations in the lightcone metric of the 4-d Einstein-Hilbert … Read More

Note: We will be in 50B-4205 this week. Title:Understanding Neural Network Behavior with the Renormalization Group Abstract:The growing presence and influence of machine learning in both science and society necessitates a better understanding of these algorithms. Interestingly, many neural network behaviors are reminiscent of physical phenomena, such as the empirically-observed approximate power law dependence of a network’s generalization performance on … Read More

Title: Monopole Baryogenesis with a theta angle Abstract: Monopoles are generally expected in Grand Unified Theories (GUTs) where they can catalyze baryon decay at an unsuppressed rate by the Callan-Rubakov effect. For the first time, we show that this catalysis effect can generate the observed baryon asymmetry at GeV-scale temperatures. We study the minimal SU(5) GUT model and demonstrate that monopole-fermion … Read More

Title: A Flavor of SO(10) Unification with a Spinor Higgs Abstract: My talk will be focused towards a relatively large audience. I will briefly review grand unified theories (GUTs) and flavor model building within GUTs.  Then I investigate the Higgs Parity Unification model. I’ll describe how 1) gauge coupling unification successfully predicts the QCD coupling to better than 1% accuracy, … Read More
