| 11:00 - 12:30 Weekly Seminar Sign of Love: positivity bounds on tidal Love number of compact objects School ASTRONOMY Abstract: I will talk about a work in progress about dispersion relations and tidal deformability of compact objects. Tidal Love number coefficient is given in terms of the two point function of the stress tensor. These are similar to the electromagnetic polarizability of an object. By using the conditions of causality and positivity one can prove positivity bounds on the Love number of weakly gravitating compact objects. ... |
