Geometric Phases Characterise Operator Algebras and Missing Information
Souvik Banerjee, Moritz Dorband, Johanna Erdmenger +1
We show how geometric phases may be used to fully describe quantum systems, with or without gravity, by providing knowledge about the geometry and topology of its Hilbert space. We…
Geometric Quantum Discord Signals Non-Factorization
Souvik Banerjee, Pablo Basteiro, Rathindra Nath Das +1
We propose the information-theoretic quantity of geometric quantum discord (GQD) as an indicator of the factorization properties of a given quantum system. In particular, we show h…
Features of a dark energy model in string theory
Souvik Banerjee, Ulf Danielsson, Suvendu Giri
In this paper we clear up misconceptions concerning the dark bubble model as a realization of dark energy in string theory. In particular we point out important differences with Ra…
A universal approach to Krylov State and Operator complexities
Mohsen Alishahiha, Souvik Banerjee
We present a general framework in which both Krylov state and operator complexities can be put on the same footing. In our formalism, the Krylov complexity is defined in terms of t…
On the saturation of late-time growth of complexity in supersymmetric JT gravity
Mohsen Alishahiha, Souvik Banerjee
In this work we use the modified replica trick, proposed in arXiv:2205.01150, to compute the late time behaviour of complexity for JT gravity with and …
Complexity via Replica Trick
Mohsen Alishahiha, Souvik Banerjee, Joshua Kames-King
We consider the complexity of a single-sided AdS black hole as modelled by an end-of-the-world brane. In addition, we present multi-boundary partition functions and matter correlat…
