Optical-conductivity sum rule in cuprates and unconventional charge density waves: a short review
L. Benfatto, S. Sharapov
We begin with an overview of the experimental results for the temperature and doping dependences of the optical-conductivity spectral weight in cuprate superconductors across the w…
Unconventional Integer Quantum Hall effect in graphene
V. P. Gusynin, S. G. Sharapov
Monolayer graphite films, or graphene, have quasiparticle excitations that can be described by 2+1 dimensional Dirac theory. We demonstrate that this produces an unconventional for…
Magnetic oscillations in planar systems with the Dirac-like spectrum of quasiparticle excitations II: transport properties
V. P. Gusynin, S. G. Sharapov
The quantum magnetic oscillations of electrical (Shubnikov de Haas effect) and thermal conductivities are studied for graphene which represents a distinctive example of planar syst…
Universal scaling of Coulomb drag in graphene layers
Irene D'Amico, S. G. Sharapov
We study the Coulomb drag transresistivity between graphene layers employing the finite temperature density response function. We analyze the Coulomb coupling between the two layer…
Effect of orbital currents on the restricted optical sum rule
L. Benfatto, S. G. Sharapov, H. Beck
We derive the restricted optical-conductivity sum rule for a model with circulating orbital currents. It is shown that an unusual coupling of the vector potential to the interactio…
Phase Fluctuations and Pseudogap Phenomena
Vadim M. Loktev, Rachel M. Quick, Sergei G. Sharapov
This article reviews the current status of precursor superconducting phase fluctuations as a possible mechanism for pseudogap formation in high-temperature superconductors. In part…
