Abstract:
While modern experimental techniques are enabling increasingly multifold studies of superconductivity (from in-situ synthesis to transport and scanning-probe measurements), the community has witnessed an increasing gap between the ab initio calculations and those on mean-field levels, and even more to the desired device modelling. At present, the only tool able to address the needed multi-scale modelling of superconductors, nanopatterned into electronic circuitry, are the advanced Ginzburg-Landau simulations. We have recently developed a multiscale approach where first information about fermiology, vibrational modes, and electron-phonon coupling are obtained from first principles for the materials of interest, to be subsequently translated into (anisotropic) superconducting properties, that can further serve to properly parametrize mean-field models to capture the behavior of that superconductor in applied magnetic field and electric current.
In this talk, I will review our further breakthroughs in that respect, and show selected numerical experimentation on circuits of arbitrary shape (on advanced size and time scale), variable thickness, inhomogeneous parameters, with self-consistent account for magnetic field distribution, the electric field generated under applied current, incorporated heating effects, thus fully characterized behavior of the superconducting condensate in nonequilibrium conditions that reveals physics behind improved or worsened performance of various realistic transport devices. As an exemplary case, I will discuss the most recent realizations of superconducting artificial neurons and quantum logic, as recently pursued in collaboration with the experimental team at KFUPM.
