Krylov Complexity: Flat bands and Carroll breaking deformations
Aritra Banerjee, Arpan Bhattacharyya, Rudranil Basu +1
Systems with flat band structures, when written in the language of Compact Localised States (CLS), have been shown to be explicitly invariant under supertranslation symmetries, mak…
Probing Topological Phases in a Strongly Correlated Ladder Model via Entanglement
Aminul Hussain, Nisa Ara, Rudranil Basu +1
The interplay between non-trivial band topology and strong electronic correlations is a central challenge in modern condensed matter physics. We investigate this competition on a t…
Light and Shadow OPEs: A Carroll Symmetric Approach to Flat Holography
Sourish Banerjee, Rudranil Basu
In this work, we fix the leading term in the operator algebra of light-transformed operators in the context of flat space holography. Starting with light-transformed graviton corre…
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…
Light transformation: A Celestial and Carrollian perspective
Sourish Banerjee, Rudranil Basu, Sayali Atul Bhatkar
In this paper, we first study the consequence of spacetime translations and Lorentz transformations on Celestial CFT OPEs. Working with the light transforms of the operators belong…
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…
