Quantum geometry from commutators: a Heisenberg-picture framework and a toy application to early structure
Vahid Kamali
We develop a Heisenberg-picture \emph{kinematical} framework in which (i) time is treated as a quantum observable, admitting both a relational POVM construction for semibounded spe…
Reheating with Axion-SU(2) and Gravitational Chern-Simons Couplings
Tatsuya Daniel, Vahid Kamali
We study the early stages of an oscillatory reheating phase in an inflaton plus spectator axion-SU(2) system, including both an axion-gauge Chern-Simons coupling and…
Direct Collapse Supermassive Black Holes from Ultralight Dark Matter
Hao Jiao, Robert Brandenberger, Vahid Kamali
We study the possibility that parametric resonant excitation of photons in an ultralight dark matter halo could generate the required flux of Lyman-Werner photons to allow the dire…
Thermal effects on warm chromoinflation
Vahid Kamali, Rudnei O. Ramos
We explore a model of a pseudo-Nambu-Goldstone boson inflaton field coupled to a non-Abelian gauge field. This model naturally leads to a warm inflation scenario, where the…
