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…
Analytical solution of a free-fermion chain with time-dependent ramps
Viktor Eisler, Riccarda Bonsignori, Stefano Scopa
We provide an exact analytical solution of the single-particle Schrödinger equation for a chain of non-interacting fermions subject to a time-dependent linear potential, with its…
Entanglement Hamiltonian and orthogonal polynomials
Pierre-Antoine Bernard, Riccarda Bonsignori, Viktor Eisler +2
We study the entanglement Hamiltonian for free-fermion chains with a particular form of inhomogeneity. The hopping amplitudes and chemical potentials are chosen such that the singl…
Domain-wall melting and entanglement in free-fermion chains with a band structure
Viktor Eisler
We study the melting of a domain wall in free-fermion chains, where the periodic variation of the hopping amplitudes gives rise to a band structure. It is shown that the entangleme…
Entanglement Hamiltonian after a local quench
Riccarda Bonsignori, Viktor Eisler
We investigate the dynamics of the entanglement Hamiltonian in a system of one-dimensional free fermions, following a local joining quench of two initially disconnected half-chains…
