Tidal Love Numbers of Black Holes and Implications from the Weak Gravity Conjecture
Abstract
The Weak Gravity Conjecture indicates that extremal black holes in the low energy effective field theory should be able to decay. This criteria gives rise to non-trivial constraints on the coefficients of higher-order derivative corrections to gravity. We will discuss the tidal deformability of neutral black holes due to higher-order derivative corrections. As a case in point, we consider a correction of cubic order in the Riemann curvature tensor. The tidal Love numbers of neutral black holes receive leading order correction from higher-order derivative terms since black holes in pure General Relativity have vanishing tidal Love numbers. We conclude that the tidal deformability of neutral black holes is constrained by the Weak Gravity Conjecture, and therefore provides a test for quantum gravity.
About the Speaker
Dr. Sam WONG received his BSc and PhD in Physics from HKUST in 2011 and 2017 respectively. He was a recipient of the Croucher Foundation Fellowship in 2017 and a Visiting Scholar at University of Southern Denmark in 2018. He is currently a Postdoctoral Research Fellow at the Department of Physics and Astronomy in The University of Pennsylvania.
Dr. Wong’s research focuses on theoretical cosmology, particle theory, string theory and supergravity. He conducts research in revealing the early cosmological history to infer the origin and fundamental nature of our universe, in particular, inflationary models and quantum nature of the early universe. He also studies baryon/lepton number violation of the standard model to understand the origin of matter anti-matter asymmetry.
