Thermal rounding of the charge-density-wave depinning transition.
The rounding of the charge density wave depinning transition by thermal noise is examined. Hops by localized modes over small barriers trigger “avalanches”, resulting in a creep velocity much larger than that expected from comparing thermal energies with typical barriers. For a field equal to the T = 0 depinning field, the creep velocity is predicted to have a power-law dependence on the temper...
متن کاملMultiple Fano effect in charge density wave systems
A general framework for analyzing the multiple Fano effect (MFE) in charge density wave (CDW) systems is developed. The MFE occurs when IR active modes have frequencies above the CDW gap and interference between the IR modes and the electronic continuum leads to a series of resonances and anti-resonances. We parameterize the peaks and dips of the absorption by a set of bare frequencies, a pinni...
متن کاملQuantum Hall Effect in chiral d - wave charge density waves
We study the electromagnetic response of a chiral dxy + id x 2 −y 2 charge density wave state. Due to parity (P) and time reversal (T) violation, Chern-Simons terms emerge in the effective action of the U(1) gauge field. As a consequence electric and magnetic fields are coupled providing the possibility of observing the Spontaneous Quantum Hall Effect i.e. generation of Hall voltage via the sol...

15 صفحه اولSliding 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...
