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…
Horizon entanglement area law from regular black hole thermodynamics
Alessio Belfiglio, S. Mahesh Chandran, Orlando Luongo +1
We investigate the thermodynamics of regular black hole configurations via quantum analogs of entropy and energy -- namely, the entanglement entropy and entanglement energy -- near…
Distinguishing bounce and inflation via quantum signatures from cosmic microwave background
S. Mahesh Chandran, S. Shankaranarayanan
Cosmological inflation is a popular paradigm for understanding Cosmic Microwave Background Radiation (CMBR); however, it faces many conceptual challenges. An alternative mechanism…
Real-space quantum-to-classical transition of time dependent background fluctuations
S. Mahesh Chandran, Karthik Rajeev, S. Shankaranarayanan
Understanding the emergence of classical behavior from a quantum theory is vital to establishing the quantum origin for the temperature fluctuations observed in the Cosmic Microwav…
Dynamical scaling symmetry and asymptotic quantum correlations for time-dependent scalar fields
S. Mahesh Chandran, S. Shankaranarayanan
In time-independent quantum systems, entanglement entropy possesses an inherent scaling symmetry that the energy of the system does not have. The symmetry also assures that entropy…
Log to log-log crossover of entanglement in dimensional massive scalar field
Parul Jain, S. Mahesh Chandran, S. Shankaranarayanan
We study three different measures of quantum correlations -- entanglement spectrum, entanglement entropy, and logarithmic negativity -- for (1+1)-dimensional massive scalar field i…
One-to-one correspondence between entanglement mechanics and black hole thermodynamics
S. Mahesh Chandran, S. Shankaranarayanan
We establish a one-to-one mapping between entanglement entropy, energy, and temperature (quantum entanglement mechanics) with black hole entropy, Komar energy, and Hawking temperat…
Divergence of entanglement entropy in quantum systems: Zero-modes
S. Mahesh Chandran, S. Shankaranarayanan
To this day, von Neumann definition of entropy remains the most popular measure of quantum entanglement. Much of the literature on entanglement entropy, particularly in the context…
