Abstract Generalizing the quantum sine-Gordon and sausage models, we construct exact S-matrices for higher spin representations with quantum U q su 2 $$ {\mathcal{U}}_{\textrm{q}}\left({\mathfrak{su}}_2\right) $$ symmetry, which satisfy unitarity, cr

Abstract The generalized hydrodynamic (GHD) approach has been extremely successful in describing the out-of-equilibrium properties of a great variety of integrable many-body quantum systems. It naturally extracts the large-scale dynamical degrees of

The staircase model is a simple generalization of the sinh-Gordon model, obtained by complexifying the coupling constant. This produces a new theory with many interesting features. Chief among them is the fact that scaling functions such as Zamolodch

In this series of lectures given at KIAS in Nov 2018, I briefly introduce the concepts of integrability, at classical and quantum level. Then I elaborate on the factorised scattering theory emerging in 1+1 integrable QFT. The Thermdynamic Bethe Ansat

We show irreversibility of the renormalization group flow in non-unitary but ${cal PT}$-invariant quantum field theory in two space-time dimensions. In addition to unbroken $mathcal{PT}$-symmetry and a positive energy spectrum, we assume standard pro

In [1], here below referred as I, we have written the set of non-linear integral equations(NLIEs) governing the finite size effects of the vacuum as well as the thermodynamics for the integrable deformation of O(3) non-linear sigma model (NLSM), gett

We investigate boundary bound states of sine-Gordon model on the finite-size strip with Dirichlet boundary conditions. For the purpose we derive the nonlinear integral equation (NLIE) for the boundary excited states from the Bethe ansatz equation of
We derive a generalization of the Destri - De Vega equation governing the scaling functions of some excited states in the Sine-Gordon theory. In particular configurations with an even number of holes and no strings are analyzed and their UV limits fo

Using a Corner Transfer Matrix approach, we compute the bipartite entanglement R\'enyi entropy in the off-critical perturbations of non-unitary conformal minimal models realised by lattice spin chains Hamiltonians related to the Forrester Baxter RSOS
