Neutron Peak in the Cuprates - The Never-Ending Story
Andrey Chubukov
(University of Maryland)
Abstract: In the talk, I will review the experimental results on
the magnetic resonance peak in the cuprates, including very recent results on
the dispersion of the peak, and on the existence of the second resonance at
higher frequencies. I will then discuss various theoretical scenarios for the
resonance peak and will argue that the exciton scenario is the most reliable
one.
