Vacuum polarization current in presence of intense Sauter field
Deepak Sah, Manoranjan P. Singh
The quantum vacuum becomes unstable under an external field, leading to spontaneous particle-antiparticle pair creation. In canonical quantization, the time-dependent particle numb…

Dynamical Scaling in Pair Production for Scalar QED
Deepak Sah, Manoranjan P. Singh
We report on the dynamical scaling of momentum spectra for particle-antiparticle pairs at finite times within the framework of scalar Quantum Electrodynamics (QED). The analysis fo…

Longitudinal Momentum Spectra of pair created in a pulsed field at finite times: Are Oscillations "Real"
Deepak Sah, Manoranjan P. Singh
We discuss the mechanism of production of electron-positron pairs from the vacuum in a time-varying, spatially uniform pulsed electric field. We analytically compute the probabilit…
