Carroll fermions, expansions and the lightcone
Arjun Bagchi, Saikat Mondal
We investigate fermions on Carrollian manifolds. We complement previous intrinsic analysis by deriving Carrollian fermion actions from a relativistic Dirac theory via a systematic…
The Tensionless Lives of Null Strings
Arjun Bagchi, Aritra Banerjee, Ritankar Chatterjee +1
The tensionless limit probes the very high energy regime of string theory in contrast to the well studied point-particle limit which reduces to Einstein gravity. Tensionless string…
Scalar fields and 3D Flat Space Cosmologies
Arjun Bagchi, Supratik Biswas, Astha Kakkar +1
Flat Space Cosmologies (FSC) are time-dependent solutions in Einstein gravity in three-dimensional (3D) spacetimes with zero cosmological constant. These are orbifolds of 3D flat s…
The Carrollian Kaleidoscope
Arjun Bagchi, Aritra Banerjee, Prateksh Dhivakar +2
The Carroll group arises in the vanishing speed of light limit of the Poincaré group and was initially discarded as just a mathematical curiosity. However, recent developments have…
Emergent Carroll symmetry at phase separation in one-dimensional lattice systems
Sourav Biswas, Ashutosh Dubey, Saikat Mondal +3
Asymptotic behavior of generic Tomonaga-Luttinger liquid in the vicinity of phase-separated regions is known to produce an instability where well-known relativistic Conformal Field…
Carroll in Shallow Water
Arjun Bagchi, Aritra Banerjee, Saikat Mondal +1
We discover a surprising connection between Carrollian symmetries and hydrodynamics in the shallow water approximation. Carrollian symmetries arise in the speed of light going to z…
