Closed form perturbative relativistic modifications to wave-packet dynamics in the quantum harmonic oscillator
Jian Carlo Ramos, Sujoy K. Modak
We derive closed form expressions of weak relativistic corrections to the wave-packet dynamics of the quantum harmonic oscillator within a perturbative framework. General expressio…

Anisotropic particle creation from vacuum in the radiation dominated universe
Dhamar S. Astilla, Sujoy K. Modak, Enrique Salazar
We further investigate novel features of the vacuum state, originally defined in the context of quantum field theory in a (1+1) dimensional radiation dominated universe [Modak,…
