Josephson junction simulation of neurons.
With the goal of understanding the intricate behavior and dynamics of collections of neurons, we present superconducting circuits containing Josephson junctions that model biologically realistic neurons. These "Josephson junction neurons" reproduce many characteristic behaviors of biological neurons such as action potentials, refractory periods, and firing thresholds. They can be coupled togeth...
متن کاملA picosecond Josephson junction model for circuit simulation
The first order series expansion of the time dependent Josephson equation allows a precise simulation of the switching dynamic of picosecond Josephson junctions. The junction model is quite as efficient as the RSJC model in computer calculations. Numerical examples illustrate its domain of application for picosecond junctions in a circuit environment by comparison with the RSJC model. Revue Phy...
متن کاملAn Extraordinary Josephson Junction
The combination of symmetry breaking effects, such as those occurring in magnets and superconductors, with topological order may result in remarkable new physics. Recent theoretical studies suggest that, in certain superconductors, exotic quasiparticle excitations can emerge that behave like Majorana fermions, chargeneutral quasiparticles that are their own antiparticles. In Physical Review Let...
متن کاملPhases of Josephson junction ladders.
We study a Josephson junction ladder in a magnetic field in the absence of charging effects via a transfer matrix formalism. The eigenvalues of the transfer matrix are found numerically, giving a determination of the different phases of the ladder. The spatial periodicity of the ground state exhibits a devil’s staircase as a function of the magnetic flux filling factor f . If the transverse Jos...
متن کاملDuality in Josephson Junction Arrays
Various properties of mesoscopic two-dimensional Josephson junction arrays are reviewed. Particular attention is paid to structure of the topological excitations, charges and vortices, which are shown to be dual to each other. This duality persists in the presence of external magnetic fields and offset charges, which influence vortices and charges in an equivalent way. A double-layer junction a...
