1. A bound on quantum chaos from Random Matrix Theory with Gaussian Unitary Ensemble / Choudhury, Sayantan ; Mukherjee, Arkaprava
In this article, using the principles of Random Matrix Theory (RMT) with Gaussian Unitary Ensemble (GUE), we give a measure of quantum chaos by quantifying Spectral From Factor (SFF) appearing from the computation of two point Out of Time Order Correlation function (OTOC) expressed in terms of square of the commutator bracket of quantum operators which are separated in time scale.

3. Quantum out-of-equilibrium cosmology / Choudhury, Sayantan ; Mukherjee, Arkaprava ; Chauhan, Prashali ; Bhattacherjee, Sandipan
In this work, our prime focus is to study the one to one correspondence between the conduction phenomena in electrical wires with impurity and the scattering events responsible for particle production during stochastic inflation and reheating implemented under a closed quantum mechanical system in early universe cosmology.

4. Bose-Fermi Chern-Simons dualities in the Higgsed phase / Choudhury, Sayantan ; Dey, Anshuman ; Halder, Indranil ; Jain, Sachin ; et al
It has been conjectured that fermions minimally coupled to a Chern-Simons gauge field define a conformal field theory (CFT) that is level-rank dual to Chern-Simons gauged Wilson-Fisher Bosons. [...]

5. Notes on melonic O( N ) q −1 tensor models / Choudhury, Sayantan ; Dey, Anshuman ; Halder, Indranil ; Janagal, Lavneet ; et al
It has recently been demonstrated that the large N limit of a model of fermions charged under the global/gauge symmetry group O( N ) q −1 agrees with the large N limit of the SYK model. [...]

In this work, we study the quantum entanglement and compute entanglement entropy in de Sitter space for a bipartite quantum field theory driven by an axion originating from Type IIB string compactification on a Calabi–Yau three fold ( CY3 ) and in the presence of an NS5 brane. [...]

9. Can dark matter be an artifact of extended theories of gravity? / Choudhury, Sayantan ; Sen, Manibrata ; Sadhukhan, Soumya
In this article, we propose different background models of extended theories of gravity, which are minimally coupled to the SM fields, to explain the possibility of genesis of dark matter without affecting the SM particle sector. [...]
