Roughening and dynamics of an electric flux string in a (2+1)D lattice gauge theory
Francesco Di Marcantonio, Sunny Pradhan, Sofia Vallecorsa +2
We investigate the roughening transition in the pure lattice gauge theory in (2+1) dimensions. Using numerical simulations with matrix product states, we explore the…
Oddities in the Entanglement Scaling of the Quantum Six-Vertex Model
Sunny Pradhan, Jesús Cobos, Enrique Rico +1
We investigate the entanglement properties of the Quantum Six-Vertex Model on a cylinder, focusing on the Shannon-Renyi entropy in the limit of Renyi order . This entro…
Quantum Fisher Information and multipartite entanglement in spin-1 chains
Federico Dell'Anna, Sunny Pradhan, Cristian Degli Esposti Boschi +1
In this paper, we study the ground state Quantum Fisher Information (QFI) in one-dimensional spin-1 models, as witness to Multipartite Entanglement. The models addressed are the Bi…
Hamiltonians and gauge-invariant Hilbert space for lattice Yang-Mills-like theories with finite gauge group
A. Mariani, S. Pradhan, E. Ercolessi
Motivated by quantum simulation, we consider lattice Hamiltonians for Yang-Mills gauge theories with finite gauge group, for example a finite subgroup of a compact Lie group. We sh…
Discrete Abelian lattice gauge theories on a ladder and their dualities with quantum clock models
Sunny Pradhan, Andrea Maroncelli, Elisa Ercolessi
We study a duality transformation from the gauge-invariant subspace of a lattice gauge theory on a two-leg ladder geometry to an -clock model on a single chain. T…
Supertranslation Hair of Schwarzschild Black Hole: A Wilson Line Perspective
Sangmin Choi, S. Sandeep Pradhan, Ratindranath Akhoury
We demonstrate within the quantum field theoretical framework that an asymptotic particle falling into the black hole implants soft graviton hair on the horizon, conforming with th…
