Precision tests of bulk entanglement entropy

Barsha G. Chowdhury, Justin R. David, Semanti Dutta +1

We consider linear superpositions of single particle excitations in a scalar field theory on $A d S_{3}$ and evaluate their contribution to the bulk entanglement entropy across the Ryu…

Entanglement in descendants

Barsha G. Chowdhury, Justin R. David

We study the single interval entanglement and relative entropies of conformal descendants in 2d CFT. Descendants contain non-trivial entanglement, though the entanglement entropy o…

Renyi divergences from Euclidean quenches

Barsha G. Chowdhury, Shouvik Datta, Justin R. David

We study the generalisation of relative entropy, the Renyi divergence $D_{α} (ρ ∣∣ ρ_{β})$ in 2 $d$ CFTs between an excited state density matrix $ρ$ , created by deforming the Hamiltonia…
