Understanding the nature of dark matter is one of the major goals of modern physics.   The abundance and density profiles of dark matter halos depend directly on dark matter particle physics. Strong gravitational lensing enables a direct measurement...

Abstract: An intrinsic quantity characterizing a scale-invariant quantum field theory (SFT) is its thermal mass gap, controlling its correlation length at finite temperature. By scale-invariance, this is a pure number in units of the temperature...

Abstract: In this talk we will describe categorical symmetries of spin chains from the viewpoint of subalgebras of the quasi-local algebra of observables in the infinite volume limit. In particular, we provide formal axioms for a subalgebra to give...

Abstract: We consider dispersive bounds on Wilson coefficients of scalar effective field theories (EFT) coupled to gravity in various spacetime dimensions, including the contributions from graviton loops to the sum rules at low energies. Dispersion...
