Entanglement Harvesting Landscapes: A Common Computational Framework
Rahul Nigam, Ujjwala Vadrevu, Akshay Kulkarni
Entanglement harvesting provides an operational means of probing the nonlocal correlation structure of quantum fields through localized detector-field interactions. Although harves…
Entanglement Entropy of Yukawa-Coupled Fields Across a Rindler Horizon
Akshay Kulkarni, Rahul Nigam
We compute the entanglement entropy across a Rindler horizon in scalar field theory with Yukawa interaction. Starting from a microscopic scalar-mediator theory in flat spacetime, w…
Entanglement Entropy for Screened Interactions via Dimensional Mapping to Harmonic Oscillators
Akshay Kulkarni, Rahul Nigam
We investigate interaction-induced corrections to entanglement entropy by mapping a screened Yukawa-type interaction to an effective harmonic oscillator system with controlled anha…
Stability analysis of an ensemble of simple harmonic oscillators
R. K. Thakur, B. N. Tiwari, R. Nigam +2
In this paper, we investigate the stability of the configurations of harmonic oscillator potential that are directly proportional to the square of the displacement. We derive expre…
