Matrix Product States with Backflow correlations
Guglielmo Lami, Giuseppe Carleo, Mario Collura
By taking inspiration from the backflow transformation for correlated systems, we introduce a novel tensor network ansatz which extend the well-established Matrix Product State rep…

Dynamics of the order-parameter statistics in the long-range Ising model
Nishan Ranabhat, Mario Collura
We study the relaxation of the local ferromagnetic order in the transverse field quantum Ising chain with power-law decaying interactions . We prepare the system in the GHZ…

Non-equilibrium spin transport in integrable spin chains: persistent currents and emergence of magnetic domains
Andrea De Luca, Mario Collura, Jacopo De Nardis
We construct exact steady states of unitary non-equilibrium time evolution in the gapless XXZ spin-1/2 chain where integrability preserves ballistic spin transport at long-times. W…
