Gravitational Waves and Cosmological Observables from First-Order Phase Transitions: Thermal Corrections at Low Temperature
Katharena Christy, James B. Dent, Sumit Ghosh +2
We consider the impact on cosmological first-order phase transitions (FOPTs) of low-temperature thermal corrections to the effective potential. These are corrections from degrees o…
Primordial black holes from Q-balls produced in a first-order phase transition
James B. Dent, Bhaskar Dutta, Jason Kumar +1
We consider the formation of Q-balls in false vacuum remnants during a cosmological first-order phase transition. We find that under certain circumstances Q-balls can collapse to f…
Opening windows with Isospin-Violating Dark Matter
Jason Kumar, Danny Marfatia, Ningqiang Song
We consider the effect of isospin-violating dark matter-nucleon interactions on direct detection constraints in the regime of small dark matter mass and large scattering cross sect…
Raiders of the Lost AdS
J. Kumar
We demonstrate that under certain conditions a theory of conformal quantum mechanics will exhibit the symmetries of two half-Virasoro algebras. We further demonstrate the condition…
Conformal Mechanics and the Virasoro Algebra
J. Kumar
We demonstrate that any scale-invariant mechanics of one variable exhibits not only 0+1 conformal symmetry, but also the symmetries of a full Virasoro algebra. We discuss the impli…
