Fast spinning strings on deformed
Aritra Banerjee, Arpan Bhattacharyya, Dibakar Roychowdhury
In this paper, considering the correspondence between spin chains and string sigma models, we explore the rotating string solutions over deformed in the…
Thermodynamics of local baths in the context of work extraction
Tamal Guha, Mir Alimuddin, Amit Mukherjee +3
We consider locally thermal states (for two qubits) with certain amount of quantum entanglement present between them. Unlike previous protocols we show how work can be extracted by…
Null hypersurface quantization, electromagnetic duality and asymptotic symmetries of Maxwell theory
Arpan Bhattacharyya, Ling-Yan Hung, Yikun Jiang
In this paper we consider introducing careful regularization in the quantization of Maxwell theory in the asymptotic null infinity. This allows systematic discussions of the commut…
Soldering freedom and BMS-like transformations
Srijit Bhattacharjee, Arpan Bhattacharyya
When two spacetimes are stitched across a null-shell placed at the horizon of a black hole BMS-supertranslation like soldering freedom arises if one demands the induced metric on t…
Quasi Static Remanence in Dzyaloshinskii-Moriya Interaction driven Weak Ferromagnets and Piezomagnets
Namrata Pattnayak, Arpan Bhattacharyya, A. K. Nigam +2
We explore remanent magnetization () as a function of time and temperature, in a variety of rhombohedral antiferromagnets (AFM) which are also weak ferromagnets (WFM) and piezom…
Tensor network and (-adic) AdS/CFT
Arpan Bhattacharyya, Ling-Yan Hung, Yang Lei +1
We use the tensor network living on the Bruhat-Tits tree to give a concrete realization of the recently proposed -adic AdS/CFT correspondence (a holographic duality based on the…
Instantons and Entanglement Entropy
Arpan Bhattacharyya, Ling-Yan Hung, Charles M. Melby-Thompson
We would like to put the area law -- believed to by obeyed by entanglement entropies in the ground state of a local field theory -- to scrutiny in the presence of non-perturbative…
