We investigate the effect of strong, nonmagnetic impurities on quasi-one-dimensional conventional and unconventional density waves (UDW). The conventional case remains unaffected similarly to s-wave superconductors in the presence of weak, nonmagnetic impurities. The thermodynamic properties of UDW were found to be identical to those of a d-wave superconductor in the unitary limit. The real and imaginary part of the optical conductivity is determined for electric fields applied in the…

The unconventional density wave (UDW) was speculated on as a possible electronic ground state in the excitonic insulator in 1968. The recent surge of interest in UDW's is partly due to the proposal
Infrared and electronic Raman response of coexisting d-wave density wave and d-wave superconductivity

High‐Tc cuprate superconductivity in a nutshell
Since the discovery of high‐Tc cuprate superconductivity in 1986 many new experimental techniques and theoretical concepts have been developed. In particular it was shown that the BCS theory of

We have investigated the collective modes of unconventional charge and spin density waves (UCDW, USDW) in quasi–one dimensional systems in random phase approximation. The density correlator regains

It is argued that even if the impurity concentration is small, the quasiparticles in the superconducting state become strongly localized for a short coherence length d-wave superconductor, which leads to thermally activated behavior for the microwave conductivity and possibly for the London penetration depth.
Imperfect nesting and transport properties in unconventional density waves
We consider the effect of imperfect nesting in quasi-one-dimensional unconventional density waves (DW's). The phase diagram is very close to those in a conventional DW's. The linear and non-linear
Theory of unconventional spin density wave: A possible mechanism of the micromagnetism in u-based heavy fermion compounds
We propose a novel spin density wave (SDW) state as a possible mechanism of the anomalous antiferromagnetism, so-called the micromagnetism, in URu_2Si_2 below 17.5[K]. In this new SDW, the

We propose a theory for quasi-two-dimensional transition metal dichalcogenides that provides a unified microscopic picture of the charge density wave (CDW) and superconducting phases. We show, based

We extend our earlier analysis to the electronic thermal conductivity κ and the frequency-dependent electric conductivity σ(ω) at low temperatures where quasi-particle scattering is dominated by
Transport properties in the d-density wave state: Wiedemann-Franz law
We study the Wiedemann-Franz (WF) law in the d-density wave (DDW) model. Even though the opening of the DDW gap (W 0 ) profoundly modifies the electronic density of states and makes it dependent on
Magnetic field dependence of the threshold electric field in unconventional charge density waves
Many experiments suggest that the unidentified low-temperature phase of α-(BEDT-TTF) 2 KHg(SCN) 4 is most likely unconventional charge density wave (UCDW). To further extend this identification we
