Oscillations and parity violation in gravitational wave background from extra tensor modes
Jaume Garriga, Mohammad Ali Gorji, Fazlollah Hajkarim +1
Spectator fields which provide additional tensor degrees of freedom, on top of the standard metric tensor perturbations, can produce significant amounts of gravitational waves (GWs…

Primordial Gravitational Waves from Phase Transitions during Reheating
Amitayus Banik, Nicolás Bernal, Fazlollah Hajkarim
We study primordial gravitational waves (GWs) generated from first-order phase transitions (PTs) during cosmic reheating. Using a minimal particle physics model, and a general para…
