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…
