Root systems and Minimal RG flows to c=1 CFTs

Changrim Ahn, Sara Kostadinovic, Francesco Ravanini

We derive exact massless S-matrices from algebraic root-system geometry and derive thermodynamic Bethe ansatz (TBA) equations that generate minimal renormalization group (RG) flows…

Hagedorn singularity in exact U_q(su(2)) S-matrix theories with arbitrary spins

Changrim Ahn, Tommaso Franzini, Francesco Ravanini

Generalizing the quantum sine-Gordon and sausage models, we construct exact S-matrices for higher spin representations with quantum U_q(su(2)) symmetry, which satisfy unitarity, cr…

The Staircase Model: Massless Flows and Hydrodynamics

Michele Mazzoni, Octavio Pomponio, Olalla A. Castro-Alvaredo +1

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.…

On the Hydrodynamics of Unstable Excitations

Olalla A. Castro-Alvaredo, Cecilia De Fazio, Benjamin Doyon +1

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…

Addendum: Nonlinear integral equations for the sausage model

Changrim Ahn, Janos Balog, Francesco Ravanini

We complete the derivation of the sausage model NLIE by giving a proof of the crucial relation (3.24) of the original paper based on the analytic properties of and .

Irreversibility of the renormalization group flow in non-unitary quantum field theory

Olalla A. Castro-Alvaredo, Benjamin Doyon, Francesco Ravanini

We show irreversibility of the renormalization group flow in non-unitary but -invariant quantum field theory in two space-time dimensions. In addition to unbroken $\math…
