Double proximity effect in hybrid planar Superconductor-(Normal metal/Ferromagnet)-Superconductor structures
Double proximity effect hybrid planar Superconductor Superconductor structures
2012/2/27
We have investigated the differential resistance of hybrid planar Al-(Cu/Fe)-Al submicron bridges at low temperatures and in weak magnetic fields. The structure consists of Cu/Fe-bilayer forming a bri...
Effect of Impurities on the Superheating field of Type II superconductors
Impurities the Superheating field Type II superconductors
2012/2/27
We consider the effect of nonmagnetic and magnetic impurities on the superheating field $H_s$ in a type-II superconductor. We solved the Eilenberger equations, which take into account the nonlinear pa...
Shape resonance for the anisotropic superconducting gaps near a Lifshitz transition: the effect of electron hopping between layers
Shape resonance anisotropic superconducting gaps effect of electron
2010/11/24
The multigap superconductivity modulated by quantum confinement effects in a superlattice of
quantum wells is presented. Our theoretical BCS approach captures the low-energy physics of a
shape reson...
Abelian and non-abelian anyons in integer quantum anomalous Hall effect and topological phase transitions via superconducting proximity effect
Abelian and non-abelian anyons integer quantum anomalous Hall effec topological phase transitions
2010/11/23
We study the quantum anomalous Hall effect described by a class of two-component Haldane
models on square lattices. We show that the latter can be transformed into a pseudospin triplet
p + ip-wave p...
Effect of charge ordering on superconductivity in high-temperature superconductors
charge ordering high-temperature superconductors
2010/11/19
It is shown that charge ordering in layered crystalline metals causes an increase in the normal
state energy of the conducting layers. If this increase in the energy exceeds the difference between th...
Tunneling conductance in strained graphene-based superconductor: Effect of asymmetric Weyl-Dirac fermions
tunneling conductance strained graphene Specular Andreev reflection
2010/11/18
Based on the BTK theory, we investigate the tunneling conductance in a uniaxially strained graphene-based normal metal (NG)/ barrier (I)/superconductor(SG) junctions. In the present model, we assume t...
Effect of weak magnetic field on quantum spin correlation in an s-wave superconductor
Effect of weak magnetic field quantum spin correlation
2010/11/22
We study the effect of a weak magnetic field on the state of the spins of a pair of electrons forming a Cooper pair in an s-wave superconductor. By perturbatively solving time-dependent Bogoliubov equ...
Striking Zn impurity effect on the Fe-based superconductor BaFe1.87Co0.13As2
Striking Zn impurity effect superconductor BaFe1.87Co0.13As2
2010/11/17
Nonmagnetic impurity effect was studied on the n-type Fe-based superconductor BaFe1.87Co0.13As2 (Tc = 25 K) by a successful Zn substitution for Fe up to 7 at.%. Magnetic susceptibility, electrical res...
Condensate-free superfluidity induced by frustrated proximity effect
Condensate-free superfluidity frustrated proximity effect
2010/10/27
Since the discovery of superfluidity in 4He and Landau’s phenomenological theory, the relationship between Bose condensation and superfluidity has been intensely debated. 4He is known by now to be bot...
