Does the XY Model have an integrable continuum limit?
J. Balog, M. Niedermaier, F. Niedermayer +3
The quantum field theory describing the massive O(2) nonlinear sigma-model is investigated through two non-perturbative constructions: The form factor bootstrap based on integrabil…

Form Factors, Thermal States and Modular Structures
M. R. Niedermaier
Form factor sequences of an integrable QFT can be defined axiomatically as solutions of a system of recursive functional equations, known as ``form factor equations''. We show that…
