Other than charge carriers, the only low-energy excitations in HTSC materials are phonons and plasmons, but each of these shows some unusual features. Certain phonons are quite polar, strongly coupled to electrons and anharmonic. An unusual Im(-1/e)o, E 2 law is attributed to plasmon spectrum being
## Recent angle resolved photoemission experiments by Kanigel et al., [Nature Physics 2 (2006) 447] show that the low energy electronic excitations in the normal state of underdoped cuprate superconductors exist on open Fermi arcs which shrink upon cooling, and appear to extrapolate to nodal poin
