Exact results in the theory of magnetic alloys
AM Tsvelick, PB Wiegmann - Advances in Physics, 1983 - Taylor & Francis
Recently it has been shown that many traditional models used for a description of dilute
magnetic alloys are completely integrable and may be solved exactly without any approximation. …

Conformal maps and integrable hierarchies
PB Wiegmann, A Zabrodin - Communications in Mathematical Physics, 2000 - Springer
We show that conformal maps of simply connected domains with an analytic boundary to a
unit disk have an intimate relation to the dispersionless 2D Toda integrable hierarchy. The …

Theta-terms in nonlinear sigma-models
AG Abanov, PB Wiegmann - Nuclear Physics B, 2000 - Elsevier
We trace the origin of θ-terms in nonlinear σ-models as a nonperturbative anomaly of current
algebras. The nonlinear σ-models emerge as a low energy limit of fermionic σ-models. The …

One-dimensional Fermi system and plane xy model
PB Wiegmann - Journal of Physics C: Solid State Physics, 1978 - iopscience.iop.org
The behaviour of correlation functions of the one-dimensional Fermi system at large distances
has been investigated by reducing it to the Sine-Gordon model. The latter is dual to the low…
