Hydrodynamics of massless integrable RG flows and a non-equilibrium c-theorem
David X. Horvath
We study Euler scale hydrodynamics of massless integrable quantum field theories interpolating between two non-trivial renormalisation group fixed points after inhomogeneous quantu…
Non-equilibrium time evolution and rephasing in the quantum sine-Gordon model
D. X. Horvath, I. Lovas, M. Kormos +2
We discuss the non-equilibrium time evolution of the phase field in the sine-Gordon model using two very different approaches: the truncated Wigner approximation and the truncated…
Overlap singularity and time evolution in integrable quantum field theory
D. X. Horváth, M. Kormos, G. Takács
We study homogeneous quenches in integrable quantum field theory where the initial state contains zero-momentum particles. We demonstrate that the two-particle pair amplitude neces…
Roaming form factors for the tricritical to critical Ising flow
D. X. Horvath, P. E. Dorey, G. Takacs
We study the massless flows described by the staircase model introduced by Al.B. Zamolodchikov through the analytic continuation of the sinh-Gordon S-matrix, focusing on the renorm…
