Spectral Density of the Causal Propagator

Joshua Y. L. Jones, Yasaman K. Yazdi

The causal propagator (or Pauli-Jordan function), which multiplied by $i$ is the spacetime commutator of the field $[ϕ (x), ϕ (x^{'})]$ , plays an essential role in scalar quantum field t…

Spectral Spacetime Entropy for Quasifree Theories

Joshua Y. L. Jones, Yasaman K. Yazdi

Motivated by the necessity to UV-regularise entanglement entropy, we present a spectral method for calculating the entropy of quasifree states, for both bosonic and fermionic field…
