Solitons in curved spacetime
Susobhan Mandal
Derrick's theorem is an important result that decides the existence of soliton configurations in field theories in different dimensions. It is proved using the extremization of fin…
Classification of quantum states based on the null energy condition
Susobhan Mandal
Violation of the null energy condition plays an important role both in the general theory of relativity and quantum field theory in curved spacetimes. Over the years, it has been s…
Characteristics of interaction between Gravitons and Photons
Athira B S, Susobhan Mandal, Subhashish Banerjee
The direct detection of gravitational waves from binary mergers has been hailed as the discovery of the century. In the light of recent evidence on the existence of gravitational w…
Existence of conserved quantities and their algebra in curved spacetime
Susobhan Mandal
In General Relativity, finding out the geodesics of a given spacetime manifold is an important task because it determines which classical processes are dynamically forbidden. Conse…
Reduced Chandrasekhar mass limit due to the fine-structure constant
Golam Mortuza Hossain, Susobhan Mandal
The electromagnetic interaction alters the Chandrasekhar mass limit by a factor which depends, as computed in the literature, on the atomic number of the positively charged nuclei…
Solitons in a class of interacting scalar field theories without invariance
Susobhan Mandal
In this article, we study kink soliton configurations in interacting scalar field theories containing two fields without invariance. We study a class of such theories, the…
