Measurement-induced entanglement Hamiltonian
Viktor Eisler, Erik Tonni
We study the entanglement Hamiltonian of an infinite hopping chain in its ground state, after partial projective measurements in the occupation basis. For a segment separated by tw…
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…
A contour for the entanglement negativity of bosonic Gaussian states
Gioele Zambotti, Erik Tonni
We construct a contour function for the logarithmic negativity and the logarithm of the moments of the partial transpose of the reduced density matrix for multimode bosonic Gaussia…
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…
Continuous majorization in quantum phase space for Wigner-positive states and proposals for Wigner-negative states
Jan de Boer, Giuseppe Di Giulio, Esko Keski-Vakkuri +1
In quantum resource theory, one is often interested in identifying which states serve as the best resources for particular quantum tasks. If a relative comparison between quantum s…
