Null reduction and dynamical realization of Carrollian conformal symmetries
Ashis Saha, Rabin Banerjee, Sunandan Gangopadhyay
We start from a Lorentzian action in a deformed light-cone background and applying the method of null reduction leads to a Carrollian action in one lower spacetime dimensions. We a…
Heterotic Warm Inflation
Arjun Berera, Heliudson Bernardo, Suddhasattwa Brahma +3
We propose a two-field model of warm inflation motivated by a heterotic string construction, involving an axion and a dilaton-like scalar field with non-trivial kinetic mixing. Gau…
Moduli Dynamics in Effective Nested Warped Geometry in Four Dimensions and Some Cosmological Implications
Arko Bhaumik, Soumitra SenGupta
We analyze the effective four-dimensional dynamics of the extra-dimensional moduli fields in curved braneworlds having nested warping, with particular emphasis on the doubly warped…
Singularities of Feynman Integrals
Tanay Pathak, Ramesh Sreekantan
In this paper, we study the singularities of Feynman integrals using homological techniques. We analyse the Feynman integrals by compactifying the integration domain as well as the…
Moduli stabilization with bulk scalar in nested doubly warped braneworld model
Arko Bhaumik, Soumitra SenGupta
We examine the modulus stabilization mechanism of a warped geometry model with nested warping. Such a model with multiple moduli is known to offer a possible resolution of the ferm…
Uncertainty Relations for the Relativistic Jackiw-Nair Anyon: A First Principles Derivation
Joydeep Majhi, Subir Ghosh
In this paper we have explicitly computed the and (Heisenberg) Uncertainty Relations for the model of relativistic particles with arbitrary…
