Abstract
We investigate the effect of a dynamical collective mode coupled with quasiparticles at specific wave vectors only. This coupling describes the incipient tendency to order and produces shadow spectral features at high energies while leaving essentially untouched the low-energy quasiparticles. This allows interpretation of seemingly contradictory experiments on underdoped cuprates, where many converging evidences indicate the presence of charge (stripe or checkerboard) order, which remains instead elusive in the Fermi surface obtained from angle-resolved photoemission experiments. © 2009 The American Physical Society.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
