Jones index from Rényi entropies in the Ising conformal field theory
Valentin Benedetti, Isai Davila-Cuba, Erik Tonni
We study the relation between the Jones index and the Rényi entropies of two disjoint intervals on the line and of the ground state for a generic value of the Rényi index in the…
Entanglement negativity for a free scalar chiral current
Malen Arias, Marina Huerta, Andrei Rotaru +1
We study the entanglement negativity for the free, scalar chiral current in two spacetime dimensions, which is a simple model violating the Haag duality in regions with nontrivial…
Modular Hamiltonian of the massive scalar field on the half line: A numerical approach
Christoph Minz, Erik Tonni
We study the modular Hamiltonian of an interval for the ground state of a massive free scalar field on the half line with Robin boundary conditions, by employing a numerical method…
Entanglement Hamiltonian for the massless Dirac field on a segment with an inhomogeneous background
Erik Tonni, Stefano Trezzi
We study the entanglement Hamiltonian of an interval for the massless Dirac field in an inhomogeneous background on a segment where the same boundary condition at both its endpoint…
Modular transport in two-dimensional conformal field theory
Mihail Mintchev, Diego Pontello, Erik Tonni
We study the quantum transport generated by the bipartite entanglement in two-dimensional conformal field theory at finite density with the symmetry associated t…
Modular evolutions and causality in two-dimensional conformal field theory
Dobrica Jovanovic, Mihail Mintchev, Erik Tonni
In two-dimensional conformal field theories (CFT) in Minkowski spacetime, we study the spacetime distance between two events along two distinct modular trajectories. When the spati…
