Abstract: The initial idea underlying the Weak Gravity Conjecture is that extremal black holes must always be “unstable”, in the sense that they should slowly decay by emitting either particles or smaller black holes. Here we… read more here.

DOI: 10.1088/1402-4896/accabb
Abstract: Modulational instability in topological photonic lattices enables the selective population of energy bands and generation of steady-state wavefields with well-defined topological invariants. This provides a way to measure bulk topological invariants, which determine the number… read more here.

DOI: 10.1103/physrevb.96.195160
Abstract: There is a close connection between various new phenomena in Weyl semimetals and the existence of linear band crossings in the single particle description. We show, by a full self-consistent mean-field calculation, how this picture… read more here.
