Recent Efforts Towards Understanding the Early Universe from a Fundamental Quantum Perspective
Sujoy K. Modak
The observable universe is fundamentally inhomogeneous and anisotropic. Quantum description of the generation of these inhomogeneities and anisotropies is ill-understood and unsati…
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,…
A novel mechanism for probing the Planck scale with wavepackets following general distributions
Saurya Das, Sujoy K. Modak
It was also shown recently that GUP predicts potentially measurable corrections to the `doubling time' of freely moving Gaussian atomic and molecular wavepackets with a favorable c…
Quantum field theory in a de Sitter universe transiting to the radiation stage
Juan R. Salazar, Sujoy K. Modak
We study some physical aspects of quantum field theory in a two stage universe starting from the inflationary de Sitter and transiting into the radiation dominated stage. We look i…
A novel mechanism for probing the Planck scale
Saurya Das, Sujoy K. Modak
The Planck or the quantum gravity scale, being orders of magnitude greater than the electroweak scale, is often considered inaccessible by current experimental techniques. How…
Cosmological Particle Creation Beyond de Sitter
Sujoy K. Modak
Over the years, de Sitter spacetime has been a central focus, in studies involving quantum fields, for its importance in the early and late expansion stages of the universe. While…
