Integrable Matrix Product States from boundary integrability
Balázs Pozsgay, Lorenzo Piroli, Eric Vernier
We consider integrable Matrix Product States (MPS) in integrable spin chains and show that they correspond to "operator valued" solutions of the so-called twisted Boundary Yang-Bax…
Integrable quenches in nested spin chains II: fusion of boundary transfer matrices
Lorenzo Piroli, Eric Vernier, Pasquale Calabrese +1
We consider quantum quenches in the integrable -invariant spin chain (Lai-Sutherland model), and focus on the family of integrable initial states. By means of a Quantum Tran…
Integrable quenches in nested spin chains I: the exact steady states
Lorenzo Piroli, Eric Vernier, Pasquale Calabrese +1
We consider quantum quenches in the integrable -invariant spin chain (Lai-Sutherland model) which admits a Bethe ansatz description in terms of two different quasiparticle s…
Spin-charge separation effects in the low-temperature transport of 1D Fermi gases
Márton Mestyán, Bruno Bertini, Lorenzo Piroli +1
We study the transport properties of a one-dimensional spinful Fermi gas, after junction of two semi-infinite sub-systems held at different temperatures. The ensuing dynamics is st…
From the sinh-Gordon field theory to the one-dimensional Bose gas: exact local correlations and full counting statistics
Alvise Bastianello, Lorenzo Piroli
We derive exact formulas for the expectation value of local observables in a one-dimensional gas of bosons with point-wise repulsive interactions (Lieb-Liniger model). Starting fro…
Entanglement evolution and generalised hydrodynamics: noninteracting systems
Bruno Bertini, Maurizio Fagotti, Lorenzo Piroli +1
The large-scale properties of homogeneous states after quantum quenches in integrable systems have been successfully described by a semiclassical picture of moving quasiparticles.…
Non-analytic behavior of the Loschmidt echo in XXZ spin chains: exact results
Lorenzo Piroli, Balázs Pozsgay, Eric Vernier
We address the computation of the Loschmidt echo in interacting integrable spin chains after a quantum quench. We focus on the massless regime of the XXZ spin-1/2 chain and present…
Exact local correlations and full counting statistics for arbitrary states of the one-dimensional interacting Bose gas
Alvise Bastianello, Lorenzo Piroli, Pasquale Calabrese
We derive exact analytic expressions for the -body local correlations in the one-dimensional Bose gas with contact repulsive interactions (Lieb-Liniger model) in the thermodynam…
