Non-fermi-liquid behavior of quasi-one-dimensional pseudogap materials.

چکیده
We study the spectral function of the pseudogap phase of quasi-one-dimensional charge density wave materials. Using a stochastic approach and emphasizing an exact treatment of non-Gaussian order parameter fluctuations we will go beyond a usual perturbative calculation. Our results give a good fit to angle-resolved photoemission spectroscopy data and explain the absence of the Fermi edge in charge density wave materials even above the Peierls transition, indicating non-Fermi-liquid behavior.

Spectroscopic evidence for Fermi liquid-like energy and temperature dependence of the relaxation rate in the pseudogap phase of the cuprates.
Cuprate high-Tc superconductors exhibit enigmatic behavior in the nonsuperconducting state. For carrier concentrations near "optimal doping" (with respect to the highest Tcs) the transport and spectroscopic properties are unlike those of a Landau-Fermi liquid. On the Mott-insulating side of the optimal carrier concentration, which corresponds to underdoping, a pseudogap removes quasi-particle s...
متن کاملNon-Fermi Behavior of the Strongly Correlated Electron Systems
(1) The temperature dependence of the specific heat for a marginal Fermi liquid has been calculated . We showed that the expected T lnT correction is characteristic for the low temperature domain. The high temperature domain has a supplementary correction. The results are in agreement with the non-Fermi behavior of some metallic systems in the low temperature domain. (2) We calculated the self-...
متن کاملCoherence-Incoherence Transition Between Fermi and Luttinger liquids
We consider conditions for existence of fermionic quasiparticles in a strongly anisotropic quasi-one-dimensional metal. The adopted model is a model of chains of spin-1/2 Luttinger liquid coupled by small interchain hopping. We determine sufficient conditions for a formation of the quasi-particle pole in the single-electron Green’s function. It is shown that the Luttinger liquid becomes more st...
متن کاملThe spectral , structural and transport properties of the pseudogap system ( TaSe 4 ) 2 I
The room temperature “metallic” properties of the quasi-one-dimensional charge density wave system (TaSe4)2I differ markedly from those expected of either a Fermi or a Luttinger Liquid. We discuss evidence for the simplest possible explanation of the observed behavior of (TaSe4)2I in its conducting phase — namely the existence of large quasi–static fluctuations of structural order, which howeve...
متن کاملOne-dimensional fermions with neither Luttinger-liquid nor Fermi-liquid behavior.
It is well known that, generically, one-dimensional interacting fermions cannot be described in terms of a Fermi liquid. Instead, they present a different phenomenology, that of a Tomonaga-Luttinger liquid: the Landau quasiparticles are ill defined, and the fermion occupation number is continuous at the Fermi energy. We demonstrate that suitable fine tuning of the interaction between fermions c...
