Time-dependent Magnetic Fields and the Quantum Hall Effect
T. R. Govindarajan, V. P. Nair
Ermakov has shown how the solution to the classical harmonic oscillator in one spatial dimension with general time-dependent frequency can be reduced to the time-independent case a…
Natural evidence for fuzzy sphere noncommutative geometry: super-Chandrasekhar white dwarfs
Surajit Kalita, T. R. Govindarajan, Banibrata Mukhopadhyay
Noncommutative geometry is one of the quantum gravity theories, which various researchers have been using to describe different physical and astrophysical systems. However, so far,…
Super-Chandrasekhar limiting mass white dwarfs as emergent phenomena of noncommutative squashed fuzzy spheres
Surajit Kalita, T. R. Govindarajan, Banibrata Mukhopadhyay
The indirect evidence for at least a dozen massive white dwarfs violating the Chandrasekhar mass-limit is considered to be one of the wonderful discoveries in astronomy for more th…
Stuckelberg SUSY QED and Infrared Problem
Radhika Vinze, T. R. Govindarajan, Anuradha Misra +1
We review gauge invariant supersymmetric massive gauge theory coupled to matter and Stuckelberg superfields. We focus on the leading order self energy and ve…
Significantly super-Chandrasekhar mass-limit of white dwarfs in noncommutative geometry
Surajit Kalita, Banibrata Mukhopadhyay, T. R. Govindarajan
Chandrasekhar made the startling discovery about nine decades back that the mass of compact object white dwarf has a limiting value, once nuclear fusion reactions stop therein. Thi…
Embedding into flat spacetime and black hole thermodynamics
T. R. Govindarajan, Sumanta Chakraborty
It is known that static and spherically symmetric black hole solutions of general relativity in different spacetimes can be embedded into higher dimensional flat spacetime. Given t…
