Inflation with a Growing Fifth Dimension
Rashmish K. Mishra, Michael Nee, Lisa Randall
Inflation generally assumes a field with nonzero potential that leads to inflationary expansion happening at arbitrarily early times. We demonstrate potentially observable conseque…
Confinement in Holographic Theories at Finite Theta
Rashmish K. Mishra
A strongly coupled confining gauge theory with a non-zero vacuum angle undergoing a deconfinement to confinement phase transition is studied in the holographic gravitational descri…
Phase Transition to RS: Cool, not Supercool
Rashmish K. Mishra, Lisa Randall
Motivated by the warped conifold compactification, we model the infrared (IR) dynamics of confining gauge theories in a Randall-Sundrum (RS)-like setup by modifying the stabilizing…
Density of States, Black Holes and the Emergent String Conjecture
Alek Bedroya, Rashmish K. Mishra, Max Wiesner
We study universal features of the density of one-particle states in weakly coupled theories of gravity at energies above the quantum gravity cutoff , defined as the sc…
Evaporating Axion Dark Matter and the Hubble Constant
Daniel Aloni, Hengameh Bagherian, Rashmish K. Mishra
Axion-like particles are a well-motivated dark matter candidate that can form a condensate with low momentum and high occupation number. In the presence of dark radiation, this con…
