    • Exact form factors in integrable quantum field theories : the scaling Z(N)-ising model 

      Babujian, Hratchya M.; Foerster, Angela; Karowski, Michael (2006) [Artigo de periódico]
      A general form factor formula for the scaling Z(N)-Ising model is constructed. Exact expressions of all matrix elements are obtained for several local operators. In addition, the commutation rules for order, disorder ...

    • Exact form factors of the SU(N) Gross–Neveu model and 1/N expansion 

      Babujian, Hratchya M.; Foerster, Angela; Karowski, Michael (2010) [Artigo de periódico]
      The general SU(N) form factor formula is constructed. Exact form factors for the field, the energy–momentum and the current operators are derived and compared with the 1/N-expansion of the chiral Gross–Neveu model and full ...
