Pair creation via Amplitude-Modulated Periodic and Quasiperiodic Pulse Sequences
Deepak Sah
We study nonperturbative pair production driven by alternating-sign electric field pulse trains. Using a quantum kinetic approach, we analyze both the longitudinal momentum spectru…

Unitarity constraints on 2HDM with higher dimensional operators
Deepak Sah
We study how the requirement of perturbative unitarity restricts the parameter space of the two-Higgs-doublet model (2HDM) when higher-dimensional operators up to dimension six are…
