Electrodynamics of a Generalized Charged Particle in Doubly Special Relativity Framework
Souvik Pramanik, Subir Ghosh, Probir Pal
In the present paper, dynamics of generalized charged particles are studied in the presence of external electromagnetic interactions. This particular extension of the free relativi…
Priomordial non-Gaussian features from DBI Galileon inflation
Sayantan Choudhury, Supratik Pal
We have studied primordial non-Gaussian features from a model of potential driven single field DBI Galileon inflation. We have computed the bispectrum from the three point correlat…
Brane inflation: A field theory approach in background supergravity
Sayantan Choudhury, Supratik Pal
We propose a model of inflation in the framework of brane cosmology driven by background supergravity. Starting from bulk supergravity we construct the inflaton potential on the br…
DBI Galileon inflation in background SUGRA
Sayantan Choudhury, Supratik Pal
We introduce a model of potential driven DBI Galileon inflation in background N=1,D=4 SUGRA. Starting from D4- brane-antibrane in the bulk N=2,D=5 SUGRA including quadrat…
Path Integral for non-relativistic Generalized Uncertainty Principle corrected Hamiltonian
Sudipta das, Souvik Pramanik
Generalized Uncertainty Principle (GUP) has brought the idea of existence of minimum measurable length in Quantum physics. Depending on this GUP, non-relativistic Hamiltonian at th…
