SUMMARY:Random loop models and quantum spin systems - Daniel Ueltschi (War
 wick)

DESCRIPTION:The random loop representations of quantum Heisenberg models a
 llow to study these systems using probabilistic methods. They were introdu
 ced twenty years ago by Toth and Aizenman-Nachtergaele. I will review rigo
 rous results and open questions. I will describe a probabilistic proof of 
 exponential decay of transverse quantum correlations (joint work with J. B
 jornberg).
