Confinement in the three-state Potts quantum spin chain in extreme ferromagnetic limit
Anna Krasznai, Sergei Rutkevich, Gábor Takács
We investigate the dynamics of the three-state Potts quantum spin chain in the extreme ferromagnetic limit using a perturbative expansion in the transverse magnetic field. We demon…
On the ground-state energy of the finite sine-Gordon ring
S. B. Rutkevich
The Casimir scaling function characterising the ground-state energy of the sine-Gordon model in a finite circle has been studied analytically and numerically both in the repulsive…
Scaling in the massive antiferromagnetic XXZ spin-1/2 chain near the isotropic point
S. B. Rutkevich
The scaling limit of the Heisenberg XXZ spin chain at zero magnetic field is studied in the gapped antiferromagnetic phase. For a spin-chain ring having sites, the universal…
Kink confinement in the antiferromagnetic XXZ spin-1/2 chain in a weak staggered magnetic field
S. B. Rutkevich
The Heisenberg XXZ spin-1/2 chain is considered in the massive antiferromagnetic regime in the presence of a staggered longitudinal magnetic field. The Hamiltonian of the model is…
Radiative corrections to the quark masses in the ferromagnetic Ising and Potts field theories
S. B. Rutkevich
We consider the Ising Field Theory (IFT), and the 3-state Potts Field Theory (PFT), which describe the scaling limits of the two- dimensional lattice q-state Potts model with q=2,…
Inverse scattering-theory approach to the exact large- solutions of models on films and semi-infinite systems bounded by free surfaces
Sergei B. Rutkevich, H. W. Diehl
The model on a strip bounded by a pair of planar free surfaces at separation can be solved exactly in the large- limit in terms of the eigenvalues and eigenfunc…
