Bipartite fidelity for models with periodic boundary conditions
Alexi Morin-Duchesne, Gilles Parez, Jean Liénardy
For a given statistical model, the bipartite fidelity is computed from the overlap between the groundstate of a system of size and the tensor product of the ground…

Bipartite fidelity of critical dense polymers
Gilles Parez, Alexi Morin-Duchesne, Philippe Ruelle
We investigate the bipartite fidelity for a lattice model described by a logarithmic CFT: the model of critical dense polymers. We define this observable in terms of…
