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…
