Low frequency dielectric response of charge density wave systems K0.3MoO3 and o-TaS3 shows hysteresis on temperature cycling. The closing of the hysteresis at low temperature coincides in both systems with the closing of the hysteresis in DC conductivity and corresponds to the temperature of the glass transition observed in dielectric response of these two systems. AC conducitivity is higher on heating, while DC conductivity is lower, i.e. two loops have opposite directions. Higher AC conducitivity (or dielectric response) is a consequence of more corrugated CDW phase on heating.

We investigated the optical properties of a series of monophosphate tungsten bronzes (P02)4(W03)2m (m=2,4, 6,7) as a function of layer thickness, with special attention on the m=7 density wave superconductor. These materials have several layers of corner-sharing WO6 octahedra separated by one PO4 layer, leading to a tunable octahedral layer thickness with m. In the optical regime, the spectra of the m=2, 4, 6, and 7 materials display an anisotropic electronic excitation, originating from the W intra t2g d to d transition. The intensities and frequencies of these excitations vary with the octahedral layer thickness, consistent with a softer lattice with increasing m. The low-frequency electrodynamics of the monophosphate tungsten bonzes show a gap or pseudogap feature in the infrared, demonstrating a ubiquitous bound camer response. The m=7 density wave superconductor is especially interesting. The variable temperature ab-plane spectra display a suppression of the optical conductivity along the b-axis below 140 K, giving rise to charge localization and anisotropic charge density wave gap formation near 1400 cm-1. This middle infrared charge localization is directly related to the appearance of both flat and dispersive bands along b. Although oscillator strength is redistributed among the free carrier response, charge density wave gap absorption, and d to d transition in the density wave states, the spectral weight is largely conserved below the plasma frequency. Based upon these observations, P4W 14050 is another example of a superconductor with an unusual normal state.
