Sliding charge-density wave in manganites.
Stripe and chequerboard phases appear in many metal oxide compounds, and are thought to be linked to exotic behaviour such as high-temperature superconductivity and colossal magnetoresistance. It is therefore extremely important to understand the fundamental nature of such phases. The so-called stripe phase of the manganites has long been interpreted as the localization of charge at atomic site...
متن کاملCharge-density-wave phase slip in NbSe3
We have studied the phase-slip process by which charge-density-wave (CDW) current is converted to single-particle current at electrical contacts. Transport and X-ray scattering measurements indicate that an excess voltage Vps dropped between current contacts induces a large static deformation of the CDW phase. The measured Vpsand temperature-dependent phase-slip rates are consistent with a mode...
متن کاملSegregation and charge-density-wave order in the spinless Falicov-Kimball model
The spinless Falicov-Kimball model is solved exactly in the limit of infinite dimensions on both the hypercubic and Bethe lattices. The competition between segregation, which is present for large U, and chargedensity-wave order, which is prevalent at moderate U, is examined in detail. We find a rich phase diagram that displays both of these phases. The model also shows nonanalytic behavior in t...
متن کاملStripe and Short Range Order in the Charge Density Wave of 1T-Cu_{x}TiSe_{2}.
We study the impact of Cu intercalation on the charge density wave (CDW) in 1T-Cu_{x}TiSe_{2} by scanning tunneling microscopy and spectroscopy. Cu atoms, identified through density functional theory modeling, are found to intercalate randomly on the octahedral site in the van der Waals gap and to dope delocalized electrons near the Fermi level. While the CDW modulation period does not depend o...
متن کاملCompetition between antiferromagnetic and charge-density-wave order in the half-filled Hubbard-Holstein model.
We present a determinant quantum Monte Carlo study of the competition between instantaneous on-site Coulomb repulsion and retarded phonon-mediated attraction between electrons, as described by the two-dimensional Hubbard-Holstein model. At half filling, we find a strong competition between antiferromagnetism (AFM) and charge-density-wave (CDW) order. We demonstrate that a simple picture of AFM-...
