Sum rules and electrodynamics of high - Tc cuprates in the pseudogap state
We explore connections between the electronic density of states ~DOS! in a conducting system and the frequency dependence of the scattering rate 1/t(v) inferred from infrared spectroscopy. We show that changes in the DOS upon the development of energy gaps can be reliably tracked through the examination of the 1/t(v) spectra using the sum rules discussed in the text. Applying this analysis to t...
متن کاملPhoto-enhanced antinodal conductivity in the pseudogap state of high-Tc cuprates
A major challenge in understanding the cuprate superconductors is to clarify the nature of the fundamental electronic correlations that lead to the pseudogap phenomenon. Here we use ultrashort light pulses to prepare a non-thermal distribution of excitations and capture novel properties that are hidden at equilibrium. Using a broadband (0.5-2 eV) probe, we are able to track the dynamics of the ...

متن کاملPseudogap Phenomena in the Superconducting Phase of the Cuprates
The presence of a normal state spectral (pseudo) gap at the superconducting transition temperature in the underdoped cuprates has important implications for the associated superconducting phase. We argue that this normal state pseudogap derives from pairing fluctuations, which necessarily persist below and which have important implications on the superconducting state. Our Greens function appro...
