Low-temperature dynamical structure factor of the two-leg spin-1/2 Heisenberg ladder
We determine the dynamical structure factor of the two-leg spin- 1 2 Heisenberg ladder at low temperatures in the regime of strong rung coupling. The dominant feature at zero temperature is the coherent triplon mode. We show that the line shape of this mode broadens in a nonsymmetric way at finite t...
