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…
