Correlated decay of triplet excitations in the shastry-sutherland compound SrCu2 (BO3)2
(
American Physical Society
, 2014 , Article)
The temperature dependence of the gapped triplet excitations (triplons) in the 2D Shastry-Sutherland quantum magnet SrCu2(BO3)2 is studied by means of inelastic neutron scattering. The excitation amplitude rapidly decreases ...
