Interacting Galilean and Finite-Energy Carroll Fermions
Pulastya Parekh, Aditya Sharma, Mauricio Valenzuela
We present a unified derivation of the Galilean and Carrollian limits of the massive Dirac action based on a similarity transformation depending on the mass and the speed of light.…
Carroll fermions from null reduction: A case of good and bad fermions
Sucheta Majumdar, Aditya Sharma, Sourav Singha
We derive Carrollian fermionic actions using the null reduction method from Bargmann spacetimes. In the Lorentzian light-cone formulation, the Dirac spinor naturally decomposes int…
Studies on Carrollian Quantum Field Theories
Aditya Sharma
We examine the quantum field description of massive Carrollian field theories, emphasizing the critical role of gauge fixing within the Carrollian sector. We illustrate this import…
Towards Carrollian quantization: renormalization of Carrollian electrodynamics
Aditya Mehra, Aditya Sharma
Field-theoretic description of Carrollian theories has largely remained classical so far. In this paper, we attempt to study the renormalization of Carrollian gauge field theories…
Galilean fermions: Classical and quantum aspects
Aditya Sharma
We study the classical and quantum "properties" of Galilean fermions in 3+1 dimensions. We have taken the case of massless Galilean fermions minimally coupled to the scalar field.…
de Sitterization via Kerr-Schild
Aditya Sharma, Kinjal Banerjee, Jishnu Bhattacharyya
Spatially homogeneous cosmological spacetimes, evolving in the presence of a positive cosmological constant and matter satisfying some reasonable energy conditions, typically appro…
Quantization of Interacting Galilean Field theories
Kinjal Banerjee, Aditya Sharma
We present the quantum field description of Galilean electrodynamics minimally coupled to massless Galilean fermion in (3 + 1) dimensions. At the classical level, the Lagrangian is…
The BTZ black hole spectrum and partition function
Omkar Vinayak Nippanikar, Aditya Sharma, K. P. Yogendran
In this article, we revisit the spectrum of the Lorentzian BTZ black hole conformal field theory. Building on a detailed analysis of geodesics, we identify a complete set of states…
Interacting Conformal Carrollian Theories: Cues from Electrodynamics
Kinjal Banerjee, Rudranil Basu, Aditya Mehra +2
We construct the free Lagrangian of the magnetic sector of Carrollian electrodynamics. The construction relies on Helmholtz integrability condition for differential equations in a…
