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…
Galileon scalar electrodynamics
Ashu Kushwaha, S. Shankaranarayanan
We construct a consistent model of Galileon scalar electrodynamics. The model satisfies three essential requirements: (1) The action contains higher-order derivative terms, and obe…
Higher derivative quartic vertex of gravity in light-cone gauge
Mahendra Mali, S. Shankaranarayanan
In the recent studies of four-dimensional Einstein-Hilbert action, quite a few interesting results such as the Kawai-Lewellen-Tye (KLT) relations, MHV-Lagrangian and quadratic form…
Role of spatial higher order derivatives in momentum space entanglement
S. Santhosh Kumar, S. Shankaranarayanan
We study the momentum space entanglement between different energy modes of interacting scalar fields propagating in general (D + 1)-dimensional flat space-time. As opposed to some…
Bekenstein-Hawking entropy from Criticality
Swastik Bhattacharya, S. Shankaranarayanan
Vacuum Einstein equations when projected on to a black hole horizon is analogous to the dynamics of fluids. In this work we address the question, whether certain properties of semi…
