Magnetic excitations of the model one-dimensional metal K0.3MnO3

Abstract: Understanding the electronic properties of low-dimensional systems remains one of the central challenges of condensed matter physics. Although great progress has been made in both experiment and theory, many formidable challenges remain. For the high-temperature cuprate superconductors, for example, one barrier to progress has been the difficulty of reconciling information provided by different experimental techniques, most notably ARPES and neutron scattering. Here we are proposing to study the magnetic excitation spectrum of the prototypical one-dimensional metal K0.3MoO3 blue bronze. Recent high-resolution ARPES measurements on K0.3MoO3 have shown clear signatures of spin-charge separation (see Fig. 1) in the presence of strong quantum fluctuations as evidenced by the anomalous broadening of the holon and spinon branches.
