Critical properties of the one-dimensional spin-1/2 antiferromagnetic Heisenberg model in the presence of a uniform field

A Fledderjohann, C Gerhardt, K H Mutter +2

In the presence of a uniform field the one-dimensional spin- antiferromagnetic Heisenberg model develops zero frequency excitations at field-dependent 'soft mode' mome…
