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


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.
