From deconfined spinons to coherent magnons in an antiferromagnetic Heisenberg chain with long range interactions
We study the nature of the excitations of an antiferromagnetic (AFM) Heisenberg chain with staggered long range interactions using the time-dependent density matrix renormalization group method and by means of a multi-spinon approximation. The chain undergoes true symmetry breaking and develops long...
