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…
Berry phases, wormholes and factorization in AdS/CFT
Souvik Banerjee, Moritz Dorband, Johanna Erdmenger +2
For two-dimensional holographic CFTs, we demonstrate the role of Berry phases for relating the non-factorization of the Hilbert space to the presence of wormholes. The wormholes ar…
