Confinement-Deconfinement Transition as an Indication of Spin-Liquid-Type Behavior in Na[subscript 2]IrO[subscript 3]

We use ultrafast optical spectroscopy to observe binding of charged single-particle excitations (SE) in the magnetically frustrated Mott insulator Na[subscript 2]IrO[subscript 3]. Above the antiferromagnetic ordering temperature (T[subscript N]) the system response is due to both Hubbard excitons (H...
