Particle creation in a time-dependent electric field revisited
Gaurang Mahajan
We adopt the general formalism for analyzing evolution of gaussian states of quantized fields in time-dependent backgrounds in the Schrodinger picture (presented in detail in arXiv…
Particle creation, classicality and related issues in quantum field theory: II. Examples from field theory
Gaurang Mahajan, T. Padmanabhan
We adopt the general formalism, which was developed in Paper I (arXiv:0708.1233) to analyze the evolution of a quantized time-dependent oscillator, to address several questions in…
Particle creation, classicality and related issues in quantum field theory: I. Formalism and toy models
Gaurang Mahajan, T. Padmanabhan
The quantum theory of a harmonic oscillator with a time dependent frequency arises in several important physical problems, especially in the study of quantum field theory in an ext…
Casimir Effect confronts Cosmological Constant
Gaurang Mahajan, Sudipta Sarkar, T. Padmanabhan
It has been speculated that the zero-point energy of the vacuum, regularized due to the existence of a suitable ultraviolet cut-off scale, could be the source of the non-vanishing…
