1. 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. [...]

2. 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. [...]

3. Entangled de Sitter from stringy axionic Bell pair I: an analysis using Bunch–Davies vacuum / Choudhury, Sayantan ; Panda, Sudhakar
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. [...]

6. 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. [...]

8. Constraining brane inflationary magnetic field from cosmoparticle physics after Planck / Choudhury, Sayantan
In this article, I have studied the cosmological and particle physics constraints on a generic class of large field (|Δ ϕ | > M p ) and small field (|Δ ϕ | < M p ) models of brane inflationary magnetic field from: (1) tensor-to-scalar ratio ( r ), (2) reheating, (3) leptogenesis and (4) baryogenesis in case of Randall-Sundrum single braneworld gravity (RSII) framework. [...]

10. Can Effective Field Theory of inflation generate large tensor-to-scalar ratio within Randall–Sundrum single braneworld? / Choudhury, Sayantan
In this paper my prime objective is to explain the generation of large tensor-to-scalar ratio from the single field sub-Planckian inflationary paradigm within Randall–Sundrum (RS) single braneworld scenario in a model independent fashion. [...]
