The MESS and dualities of cosmological perturbations
We introduce two new effective quantities for the study of comoving curvature perturbations ζ : the space dependent effective sound speed (SESS) and the momentum dependent effective sound speed (MESS)...

Dark matter with baryon and lepton numbers
The stability of dark matter and its interactions with the Standard Model remain some of the biggest mysteries of our time. Instead of inventing ad hoc stabilization symmetries I propose...
