Entanglement Dynamics after a Quench in Ising Field Theory: A Branch Point Twist Field Approach
Olalla A. Castro-Alvaredo, Máté Lencsés, István M. Szécsényi +1
We extend the branch point twist field approach for the calculation of entanglement entropies to time-dependent problems in 1+1-dimensional massive quantum field theories. We focus…
Entanglement Content of Quantum Particle Excitations III. Graph Partition Functions
Olalla A. Castro-Alvaredo, Cecilia De Fazio, Benjamin Doyon +1
We consider two measures of entanglement, the logarithmic negativity and the entanglement entropy, between regions of space in excited states of many-body systems formed by a finit…
Entanglement Content of Quantum Particle Excitations II. Disconnected Regions and Logarithmic Negativity
Olalla A. Castro-Alvaredo, Cecilia De Fazio, Benjamin Doyon +1
In this paper we study the increment of the entanglement entropy and of the (replica) logarithmic negativity in a zero-density excited state of a free massive bosonic theory, compa…
