The nested SU(N) off-shell Bethe ansatz and exact form factors
Hratchia M. Babujian, Angela Foerster, Michael Karowski
The form factor equations are solved for an SU(N) invariant S-matrix under the assumption that the anti-particle is identified with the bound state of N-1 particles. The solution i…
The Form Factor Program: a Review and New Results - the Nested SU(N) Off-Shell Bethe Ansatz
Hratchya M. Babujian, Angela Foerster, Michael Karowski
The purpose of the ''bootstrap program'' for integrable quantum field theories in 1+1 dimensions is to construct explicitly a model in terms of its Wightman functions. In this arti…
Exact form factors in integrable quantum field theories: the scaling Z(N)-Ising model
H. Babujian, A. Foerster, M. Karowski
A general form factor formula for the scaling Z(N)-Ising model is constructed. Exact expressions for matrix elements are obtained for several local operators. In addition, the comm…
Nonrelativistic Quantum Particle in a Curved Space as a Constrained System
A. Foerster, H. O. Girotti, P. S. Kuhn
The operator and the functional formulations of the dynamics of constrained systems are explored for determining unambiguously the quantum Hamiltonian of a nonrelativistic particle…
