Abstract

We analyze the spin relaxation time 1∕T₁ 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∕T₁ in the various dimensional regimes, and discuss the experimental consequences.
