Abstract

The strange metal phase is characteristic for the $T$-linear dc resistivity behaviour over a large $T$-range. The effect of the strength of the charge-paramagnon interactions on the charge fluctuations in optimally doped and underdoped regions of Bi$_2$Sr$_2$CaCu$_2$O$_{8+y}$ (Bi-2212) may shine light on the anomalous behaviour of the optical conductivity response in the energy range 50 - 500 meV. We present a preliminary analysis of a single initial run of electron energy loss spectroscopy (EELS) measurements done in a scanning transmission electron microscope (STEM) which exhibit linear dispersive modes separated by 50 meV energy gaps up to 250 meV in optimally doped Bi-2212. Our observations show similarities with the fluctuating stripes as predicted by Zaanen.
