Proposed parametric cooling of bilayer cuprate superconductors by terahertz excitation.
We propose and analyze a scheme for parametrically cooling bilayer cuprates based on the selective driving of a c-axis vibrational mode. The scheme exploits the vibration as a transducer making the Josephson plasma frequencies time dependent. We show how modulation at the difference frequency between the intrabilayer and interbilayer plasmon substantially suppresses interbilayer phase fluctuati...
متن کاملCharge Dynamics in Cuprate Superconductors
In this lecture we present some interesting issues that arise when the dynamics of the charge carriers in the CuO2 planes of the high temperature superconductors is considered. Based on the qualitative picture of doping, set by experiments and some previous calculations, we consider the strength of various inter and intra-cell charge transfer susceptibilities, the question of Coulomb screening ...
متن کاملTuning order in cuprate superconductors
In 1986, superconductivity—the ability to transport electrical current without significant resistance—was discovered in cuprate compounds. These materials have fascinated physicists ever since, in part because of the high critical temperatures (Tc’s) below which superconductivity is present and the consequent promise of technological applications. However, cuprate superconductivity also raises ...
متن کاملPairing symmetry in cuprate superconductors
Pairing symmetry in the cuprate superconductors is an important and controversial topic. The recent development of phase-sensitive tests, combined with the refinement of several other symmetry-sensitive techniques, has for the most part settled this controversy in favor of predominantly d-wave symmetry for a number of optimally holeand electron-doped cuprates. This paper begins by reviewing the...
