We consider the unitary time evolution of a one-dimensional quantum system which is in a stationary state for negative times and then undergoes a sudden change (quench) of a parameter of its Hamiltonian at t=0. For systems possessing a continuum limit described by a massive quantum field theory we investigate in general perturbative quenches for the case in which the theory is integrable before the quench.

  1. A Toy Model for Topological Entanglement Features in 1+1D Integrable Quantum Field Theory

    hep-th 2026-07 conditional novelty 6.0

    In the Federbush model, branch-point twist field form factors and first-order quench corrections are independent of the topological coupling λ, so Rényi entropies of the infinite-volume vacuum match two free Dirac fermions.

  2. Expectation values after an integrable boundary quantum quench

    hep-th 2026-05 unverdicted novelty 6.0

    A form factor framework is introduced to compute expectation values and time evolution after an integrable boundary quantum quench, applied to the Lee-Yang model at conformal and massive points with TCSA validation.

  3. Expectation values after an integrable boundary quantum quench

    hep-th 2026-05 unverdicted novelty 6.0

    A form-factor-based framework is introduced for expectation values after an integrable boundary quantum quench in the Lee-Yang model and validated numerically via adapted truncated conformal space approach.

    cond-mat.stat-mech 2025-08 unverdicted novelty 6.0

    Perturbative study of the three-state Potts model reveals hybridization of kink excitations with bound states and analytic post-quench evolution that matches numerical simulations.
