Multimode physics of the unimon circuit
Sasu Tuohino, Vasilii Vadimov, Wallace S. Teixeira +3
We consider a superconducting half-wavelength resonator that is grounded at its both ends and contains a single Josephson junction. Previously this circuit was considered as a unim…
Nonlinear response theory for lossy superconducting quantum circuits
V. Vadimov, M. Xu, J. T. Stockburger +2
We introduce a numerically exact and computationally feasible nonlinear-response theory developed for lossy superconducting quantum circuits based on a framework of quantum dissipa…
Topologically Protected Vortex Knots in an Experimentally Realizable System
Hermanni Rajamäki, Toni Annala, Mikko Möttönen
Ordered media often support vortex structures with intriguing topological properties. Here, we investigate non-Abelian vortices in tetrahedral order, which appear in the cyclic pha…
Quantum-circuit refrigeration of a superconducting microwave resonator well below a single quantum
Arto Viitanen, Timm Mörstedt, Wallace S. Teixeira +4
We experimentally demonstrate a recently proposed single-junction quantum-circuit refrigerator (QCR) as an in-situ-tunable low-temperature environment for a superconducting 4.7-GHz…
Compact inductor-capacitor resonators at sub-gigahertz frequencies
Qi-Ming Chen, Priyank Singh, Rostislav Duda +8
Compact inductor-capacitor (LC) resonators, in contrast to coplanar waveguide (CPW) resonators, have a simple lumped-element circuit representation but usually call for sophisticat…
Bordism invariants of colored links and topologically protected tricolorings
Toni Annala, Hermanni Rajamäki, Mikko Möttönen
We construct invariants of colored links using equivariant bordism groups of Conner and Floyd. We employ this bordism invariant to find the first examples of topological vortex kno…
