Quantum Field Theory On Causal Sets
Nomaan X
We give a broad overview of a construction of a theory for matter on fixed causal set backgrounds. We introduce the Sorkin-Johnston formalism for a free (real) scalar field theory…

Motivating semiclassical gravity: a classical-quantum approximation for bipartite quantum systems
Viqar Husain, Irfan Javed, Sanjeev S. Seahra +1
We derive a "classical-quantum" approximation scheme for a broad class of bipartite quantum systems from fully quantum dynamics. In this approximation, one subsystem evolves via cl…

Spacetime Entanglement Entropy: Covariance and Discreteness
Abhishek Mathur, Sumati Surya, Nomaan X
We review some recent results on Sorkin's spacetime formulation of the entanglement entropy (SSEE) for a free quantum scalar field both in the continuum and in manifold-like causal…
