Non - linear conductivity of charge - density - wave systems
We consider the problem of sliding motion of a charge-density-wave subject to static disorder within an elastic medium model. Starting with a field-theoretical formulation, which allows exact disorder averaging, we propose a self-consistent approximation scheme to obtain results beyond the standard large-velocity expansion. Explicit calculations are carried out in three spatial dimensions. For ...
متن کاملNon-linear electrical response in a charge/orbital ordered Pr0.63Ca0.37MnO3 crystal: the charge density wave analogy.
Non-linear electrical response in a charge/orbital ordered Pr 0.63 Ca 0.37 MnO 3 crystal : the charge density wave analogy. Abstract Non-linear conduction in a charge-ordered manganese oxide Pr 0.63 Ca 0.37 MnO 3 is reported. To interpret such a feature, it is usually proposed that a breakdown of the charge or orbitally ordered state is induced by the current. The system behaves in such a way t...
متن کاملCharge density wave transport in inorganic linear chain compounds
2014 In quasi-one dimensional inorganic conductors such as the transition metal trichalcogenides NbSe3, TaS3, the tetrachalcogenides (TaSe4)2I, (NbSe4)10/3I and the molybdenum blue bronzes A0.30MoO3 (A = K, Rb, T1) a new collective transport by the macroscopic sliding of a so-called charge density wave through the lattice has been reported. We review the structural and electronic properties of ...

15 صفحه اولAlternative route to charge density wave formation in multiband systems.
Charge and spin density waves, periodic modulations of the electron, and magnetization densities, respectively, are among the most abundant and nontrivial low-temperature ordered phases in condensed matter. The ordering direction is widely believed to result from the Fermi surface topology. However, several recent studies indicate that this common view needs to be supplemented. Here, we show ho...
