Gauge choices and Entanglement Entropy of two dimensional lattice gauge fields
Zhi Yang, Ling-Yan Hung
In this paper, we explore the question of how different gauge choices in a gauge theory affect the tensor product structure of the Hilbert space in configuration space. In particul…
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…
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…
