Powerlaw optical conductivity with a constant phase angle in high Tc superconductors
D. van der Marel, H. J. A. Molegraaf, J. Zaanen +7
In certain materials with strong electron correlations a quantum phase transition (QPT) at zero temperature can occur, in the proximity of which a quantum critical state of matter…
The c-axis optical sum rule and possible new collective mode in LSCO
A. B. Kuzmenko, N. Tombros, H. J. A. Molegraaf +3
We present the c-axis optical conductivity of underdoped ( = 0.12) and optimally doped ( = 0.15) LSCO from 4 meV to 1.8 eV obtained by a combination of reflect…
Superconductivity by Kinetic Energy Saving?
D. van der Marel, H. J. A. Molegraaf, C. Presura +1
A brief introduction is given in the generic microscopic framework of superconductivity. The consequences for the temperature dependence of the kinetic energy, and the correlation…
Optical signatures of electron correlations in the cuprates
D. van der Marel
The f-sum rule is introduced and its applications to electronic and vibrational modes are discussed. A related integral over the intra-band part of sigma(omega) which is also valid…
