Flat Bands and Compact Localised States: A Carrollian roadmap
Nisa Ara, Aritra Banerjee, Rudranil Basu +1
We show how Carrollian symmetries become important in the construction of one-dimensional fermionic systems with all flat-band spectra from first principles. The key ingredient of…
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…
Strings, Virasoro Sandwiches and Worldsheet Horizons
Arjun Bagchi, Aritra Banerjee, Ida M. Rasulian +1
We revisit the canonical quantization of free bosonic closed string theory and observe that the physicality of states requires vanishing of the worldsheet Virasoro algebra generato…
Strings near black holes are Carrollian -- Part II
Arjun Bagchi, Aritra Banerjee, Jelle Hartong +2
We study classical closed bosonic strings probing the near-horizon region of a non-extremal black hole and show that this corresponds to understanding string theory in the Carroll…
Symmetry Resolution in non-Lorentzian Field Theories
Aritra Banerjee, Rudranil Basu, Arpan Bhattacharyya +1
Starting from the computation of Symmetry Resolved Entanglement Entropy (SREE) for boosted intervals in a two dimensional Conformal Field Theory, we compute the same in various non…
Beyond Wilson? Carroll from current deformations
Arjun Bagchi, Aritra Banerjee, Saikat Mondal +2
At extreme energies, both low and high, the spacetime symmetries of relativistic quantum field theories (QFTs) are expected to change with Galilean symmetries emerging in the very…
