Lorentzian path integral in Kantowski-Sachs anisotropic cosmology
Saumya Ghosh, Arnab Acharya, Sunandan Gangopadhyay +1
Motivated by the recent development in quantum cosmology, we revisit the anisotropic Kantowski-Sachs model in the light of a Lorentzian path integral formalism. Studies so far have…

Meissner like effect in holographic superconductors with back reaction
Suchetana Pal, Saumya Ghosh, Sunandan Gangopadhyay
In this article we employ the matching method to analytically investigate the properties of holographic superconductors in the framework of Maxwell electrodynamics taking into acco…

Anisotropic scalar-metric quantum cosmology and unitarity
Saumya Ghosh, Sunandan Gangopadhyay, Prasanta K. Panigrahi
In this article we perform the Wheeler-DeWitt quantization for Bianchi type anisotropic cosmological model in the presence of a scalar field minimally coupled to the Einstein-H…
