Semiclassical dynamics of a superconducting circuit: chaotic dynamics and fractal attractors
arXiv (Cornell University)(2023)
摘要
We study here the semiclassical dynamics of a superconducting circuit
constituted by two Josephson junctions in series, in the presence of a voltage
bias. We derive the equations of motion for the circuit through a Hamiltonian
description of the problem, considering the voltage sources as semi-holonomic
constraints. We find that the dynamics of the system corresponds to that of a
planar rotor with an oscillating pivot. We show that the system exhibits a rich
dynamical behaviour with chaotic properties and we present a topological
classification of the cyclic solutions, providing insight into the fractal
nature of the dynamical attractors.
