Finite time path field theory and a new type of universal quantum spin chain quench behavior

Domagoj Kuić, Alemka Knapp, Diana Šaponja-Milutinović

We discuss different quench protocols for Ising and XY spin chains in a transverse magnetic field. With a sudden local magnetic field quench as a starting point, we generalize our…

Finite time path field theory perturbative methods for local quantum spin chain quenches

Domagoj Kuić, Alemka Knapp, Diana Šaponja-Milutinović

We discuss local magnetic field quenches using perturbative methods of finite time path field theory (FTPFT) in the following spin chains: Ising and XY in a transverse magnetic fie…
