Finite-temperature dynamical structure factor of alternating Heisenberg chains
We develop a low-temperature expansion for the finite-temperature dynamical structure factor of the spin half Heisenberg chain with alternating nearest-neighbor exchange in the limit of strong alternation of the exchange constants. We determine both the broadening of the low-lying triplet lines and...
