Results about entanglement (or modular) Hamiltonians of quantum many‐body systems in
field theory and statistical mechanics models, and recent applications in the context of …

We study the entanglement Hamiltonian for finite intervals in infinite quantum chains for two
different free-particle systems: coupled harmonic oscillators and fermionic hopping models …

We introduce a family of quantum Rényi fidelities and discuss their symmetry resolution. We
express the symmetry-resolved fidelities as Fourier transforms of charged fidelities, for which …

The entanglement of non-complementary regions is investigated in an inhomogeneous free-
fermion chain through the lens of the fermionic logarithmic negativity. Focus is on the …

We introduce an inhomogeneous model of free fermions on a (D− 1)-dimensional lattice with
D (D− 1)/2 continuous parameters that control the hopping strength between adjacent sites …

We consider free-fermion chains in the ground state and the entanglement Hamiltonian for a
subsystem consisting of two separated intervals. In this case, one has a peculiar long-range …

Free fermions on Hamming graphs H (d, q) are considered and the entanglement entropy for
two types of subsystems is computed. For subsets of vertices that form Hamming subgraphs …

This study investigates the scaling behavior of the ground-state entanglement entropy in a
model of free fermions on folded cubes. An analytical expression is derived in the large …

This paper offers a review of recent studies on the entanglement of free-fermion systems on
graphs that take advantage of methods pertaining to signal processing and algebraic …

Free fermions on Johnson graphs J (n, k) are considered, and the entanglement entropy of
sets of neighborhoods is computed. For a subsystem composed of a single neighborhood …
