Entanglement entropy and negativity in the Ising model with defects
David Rogerson, Frank Pollmann, Ananda Roy
Defects in two-dimensional conformal field theories (CFTs) contain signatures of their characteristics. In this work, we compute the entanglement entropy (EE) and the entanglement…

Entanglement entropy in the Ising model with topological defects
Ananda Roy, Hubert Saleur
Entanglement entropy~(EE) contains signatures of many universal properties of conformal field theories~(CFTs), especially in the presence of boundaries or defects. In particular, {…
