Critical properties and Bose Einstein Condensation in dimer spin systems

Abstract : We analyze the spin relaxation time 1/T_1 for a system made of weakly coupled one dimensional ladders.This system allows to probe the dimensional crossover between a Luttinger liquid and a Bose-Einstein condensateof magnons. We obtain the temperature dependence of 1/T_1 in the various dimensional regimes, and discuss the experimental consequences.
