Title: Critical properties and Bose-Einstein condensation in dimer spin systems

Abstract

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