Squeezed Thermal State Representation of the Inflaton and Particle Production in Bianchi type-I Universe
Karam Chand
In this study, we use a single-mode squeezed thermal vacuum state formalism and examine the nature of a massive homogeneous scalar field, minimally coupled to the gravity in the fr…

Corroborating pseudoscalar probing model with pulsar polarisation datasets
Karam Chand, Subhayan Mandal
Recently, we have used, pulsar polarisation datasets, on circular polarisation degree & linear polarisation position angle, to relate with well established theories, on ellipticity…

Probing Pseudoscalars with Pulsar Polarisation Data Sets
Karam Chand, Subhayan Mandal
Recently a data set containing linear and circular polarisation information of a collection of six hundred pulsars has been released. The operative radio wavelength for the same wa…
