Broken particle-hole symmetry at atomically flat a-axis YBa2Cu3O7-d interfaces
Bruce A. Davidson, Revaz Ramazashvili, Simon Kos +1
We have studied quasiparticle tunneling into atomically flat a-axis films of YBa2Cu3O7-d and DyBa2Cu3O7-d through epitaxial CaTiO3 barriers. The junction heterostructures were grow…
Zero-Bias States and the Mechanism of the Surface d->d+is Transition
Simon Kos
We study the physical mechanism of the surface d->d+is transition proposed as the interpretation of results of tunneling experiments into ab planes. We base our argument on first-o…
Physical Mechanism of the d->d+is Transition
Simon Kos
We discuss the basic physical mechanism of the d->d+is transition, which is the currently accepted explanation for the results of tunneling experiments into planes. Using the…
The Gradient Expansion for the Free-Energy of a Clean Superconductor
Simon Kos, Michael Stone
We describe a novel method for obtaining the gradient expansion for the free energy of a clean BCS superconductor. We present explicit results up to fourth order in the gradients o…
Free Energy of an Inhomogeneous Superconductor: a Wave Function Approach
Ioan Kosztin, Simon Kos, Michael Stone +1
A new method for calculating the free energy of an inhomogeneous superconductor is presented. This method is based on the quasiclassical limit (or Andreev approximation) of the Bog…
