Full counting statistics in the sine-Gordon model
Botond C. Nagy, Marton Kormos, Márton Kormos +2
Full counting statistics (FCS) is a dynamical generalisation of the free energy, encapsulating detailed information about the distribution and large-scale correlation functions of…
Ginzburg-Landau description for multicritical Yang-Lee models
Máté Lencsés, Alessio Miscioscia, Giuseppe Mussardo +1
We revisit and extend Fisher's argument for a Ginzburg-Landau description of multicritical Yang-Lee models in terms of a single boson Lagrangian with potential . We…
Form factor bootstrap in the thermally perturbed tricritical Ising model
B. Fitos, G. Takacs
We derive a systematic construction for form factors of relevant fields in the thermal perturbation of the tricritical Ising model, an integrable model with scattering amplitudes d…
Thermodynamic Bethe Ansatz and Generalised Hydrodynamics in the sine-Gordon model
B. C. Nagy, G. Takács, M. Kormos
We set up a hydrodynamic description of the non-equilibrium dynamics of sine-Gordon quantum field theory for generic coupling. It is built upon an explicit form of the Bethe Ansatz…
Escaping fronts in local quenches of a confining spin chain
A. Krasznai, G. Takács
We consider local quenches from initial states generated by a single spin-flip in either the true or the false vacuum state of the confining quantum Ising spin chain in the ferroma…
