Emergence of volume-law scaling for entanglement negativity from the Hawking radiation of analogue black holes
S. Mahesh Chandran, Uwe R. Fischer
The quantum information content of Hawking radiation holds the key to understanding black-hole evaporation and the fate of unitarity. Motivated by recent advances in cold-atom expe…

Entanglement scaling and dynamics in the Sauter-Schwinger effect
S. Mahesh Chandran, Karthik Rajeev
In quantum field theory, entanglement entropy under spatial bipartitioning serves as a powerful information-theoretic probe of quantum correlations. In this work, we present the fi…

Expansion-contraction duality breaking in a Planck-scale sensitive cosmological quantum simulator
S. Mahesh Chandran, Uwe R. Fischer
We propose the experimental simulation of cosmological perturbations governed by a Planck-scale induced Lorentz violating dispersion, aimed at distinguishing between early-universe…
