Spatially Selective and Reversible Doping Control in Cuprate Films

, 2005
We describe a reversible, spatially-controlled doping method for cuprate films. The technique has been used to create superconductor-antiferromagnetic insulator-superconductor (S-AFI-S) junctions and optimally doped superconductor-underdoped ...

Spontaneous Hall effect in chiral p-wave superconductor [PDF]

, 2001
In a chiral superconductor with broken time-reversal symmetry a ``spontaneous Hall effect'' may be observed. We analyze this phenomenon by taking into account the surface properties of a chiral superconductor.

Terahertz Resonators Based on YBa₂Cu₃O₇ High-T_c Superconductor

Applied Sciences, 2022
Superconducting split-ring resonator arrays allow to overcome two main limitations affecting metallic metamaterial resonating in the terahertz (THz) range: ohmic losses and tunability of their optical response.

Andreev reflection at the interface with an oxide in the quantum Hall regime [PDF]

, 2018
Quantum Hall/superconductor junctions have been an attractive topic as the two macroscopically quantum states join at the interface. Despite longstanding efforts, however, experimental understanding of this system has not been settled yet.

Ginzburg-Landau theory of dirty two band $s_{\pm}$ superconductors

, 2009
In this paper we study the effect of non-magnetic impurities on two-band $s_{\pm}$ superconductors by deriving the corresponding Ginzburg-Landau (GL) equation.
