Abstract
A phenomenological model is constructed which can reconcile the simultaneous existence of low-energy Bogoljubov quasiparticles and high-energy electronic order as observed by scanning tunneling microscopy (STM) experiments in cuprates. The theory can account for the high-energy contrast reversal in the STM spectra between positive and negative bias as characteristic for charge-density wave scattering. On the other hand the low-energy Fourier-transform of the local density of states is an even function of bias which provides an alternative to the formation of pair-density waves.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
