Mutually local fields from form factors
O. A. Castro-Alvaredo, A. Fring
We compare two different methods of computing form factors. One is the well established procedure of solving the form factor consistency equations and the other is to represent the…
Unstable particles versus resonances in impurity systems, conductance in quantum wires
O. A. Castro-Alvaredo, A. Fring
We compute the DC conductance for a homogeneous sine-Gordon model and an impurity system of Luttinger liquid type by means of the thermodynamic Bethe ansatz and standard potential…
Bootstrap Methods in 1+1-Dimensional Quantum Field Theories: The Homogeneous Sine-Gordon Models
Olalla A. Castro-Alvaredo
The bootstrap program for 1+1-dimensional integrable Quantum Field Theories (QFT's) is developed to a large extent for the Homogeneous sine-Gordon (HSG) models. This program can be…
Form factors from free fermionic Fock fields, the Federbush model
Olalla Castro-Alvaredo, Andreas Fring
By representing the field content as well as the particle creation operators in terms of fermionic Fock operators, we compute the corresponding matrix elements of the Federbush mod…
Constructing Infinite Particle Spectra
O. A. Castro-Alvaredo, A. Fring
We propose a general construction principle which allows to include an infinite number of resonance states into a scattering matrix of hyperbolic type. As a concrete realization of…
Scaling functions from q-deformed Virasoro characters
O. A. Castro-Alvaredo, A. Fring
We propose a renormalization group scaling function which is constructed from q-deformed fermionic versions of Virasoro characters. By comparison with alternative methods, which ta…
