Effective Field Theories for Material Media
Angelo Esposito, Alberto Nicolis, Riccardo Penco
We review recent progress in understanding certain aspects of condensed matter systems from a high energy theory perspective. We discuss effective field theories that describe coll…

Geometric Symmetries for the Vanishing of the Black Hole Tidal Love Numbers
Roman Berens, Lam Hui, Daniel McLoughlin +2
We present a unified geometric perspective on the symmetries underlying the spin 0, 1 and 2 static perturbations around a Schwarzschild black hole. In all cases, the symmetries are…

Effective Description of Ajar Systems with a Symmetry
Can Onur Akyuz, Riccardo Penco
We introduce the concept of "ajar systems" as an intermediate case between closed and open systems, where the time scale for charge exchange with the environment is parametrically…
