Spectral Signatures of Nontrivial Topology in a Superconducting Circuit

open access: yesPhysical Review X
Topology, like symmetry, is a fundamental concept in understanding general properties of physical systems. In condensed matter, nontrivial topology may manifest itself as singular features in the energy spectrum or the quantization of electrical ...

Frequency response and gap tuning for nonlinear electrical oscillator networks. [PDF]

open access: yesPLoS ONE, 2013
We study nonlinear electrical oscillator networks, the smallest example of which consists of a voltage-dependent capacitor, an inductor, and a resistor driven by a pure tone source. By allowing the network topology to be that of any connected graph, such
