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…
