The QCD spin chain S matrix
Changrim Ahn, Rafael I. Nepomechie, Junji Suzuki
Beisert et al. have identified an integrable SU(2,2) quantum spin chain which gives the one-loop anomalous dimensions of certain operators in large N QCD. We derive a set of nonlin…
Parity and Charge Conjugation Symmetries and S Matrix of the XXZ Chain
Anastasia Doikou, Rafael I. Nepomechie
We formulate the notion of parity for the periodic XXZ spin chain within the Quantum Inverse Scattering Method. We also propose an expression for the eigenvalues of the charge conj…
Introduction to the Thermodynamics of Spin Chains
Luca Mezincescu, Rafael I. Nepomechie
We review how to obtain the thermodynamic Bethe Ansatz (TBA) equations for the antiferromagnetic Heisenberg ring in an external magnetic field. We review how to solve these equatio…
Models with Quantum Symmetry and their Spectra
Luca Mezincescu, Rafael I. Nepomechie
We review how to construct a large class of integrable quantum spin chains with quantum-algebra symmetry, and how to determine their spectra. (To appear in Louis Witten Festschrift…
Exactly Solved Models with Quantum Algebra Symmetry
Luca Mezincescu, Rafael I. Nepomechie
We have constructed and solved various one-dimensional quantum mechanical models which have quantum algebra symmetry. Here we summarize this work, and also present new results on g…
