Superconducting proximity effect and order parameter fluctuations in disordered and quasiperiodic systems
Gautam Rai, Stephan Haas, Anuradha Jagannathan
We study the superconducting proximity effect in inhomogeneous systems in which a disordered or quasicrystalline normal-state wire is connected to a BCS superconductor. We self-con…
Spatial BCS-BEC crossover in superconducting p-n junctions
A. Niroula, G. Rai, S. Haas +1
We present a theory of superconducting p-n junctions. We consider a 2-band model of doped bulk semiconductors with attractive interactions between the charge carriers and derive th…
Induced superconducting pair correlations in a quasicrystal coupled to a BCS superconductor
Gautam Rai, Stephan Haas, Anuradha Jagannathan
In this report, we describe the proximity effect which arises when a quasicrystal is placed in contact with a superconductor. We consider the simplest known model of a quasicrystal…
The Proximity Effect in a Superconductor-Quasicrystal Hybrid Ring
Gautam Rai, Stephan Haas, Anuradha Jagannathan
We compute the real-space profile of the superconducting order parameter (OP) in a hybrid ring that consists of a 1D superconductor connected to a Fibonacci chain using a self-cons…
