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…

Entanglement Entropy of Disjoint Spacetime Intervals in Causal Set Theory
Callum F. Duffy, Joshua Y. L. Jones, Yasaman K. Yazdi
A more complete understanding of entanglement entropy in a covariant manner could inform the search for quantum gravity. We build on work in this direction by extending previous re…
