Sideband transitions in a two-mode Josephson circuit driven beyond the rotating wave approximation

Kavli Affiliate: Gary A. Steele | First 5 Authors: Byoung-moo Ann, Wouter Kessels, Gary. A. Steele, , | Summary: Driving quantum systems periodically in time plays an essential role in the coherent control of quantum states. The rotating wave approximation (RWA) is a good approximation technique for weak and nearly-resonance driven fields. However, these experiments […]

Minimal Zeeman field requirement for a topological transition in superconductors

Kavli Affiliate: Michael Wimmer | First 5 Authors: Kim Pöyhönen, Daniel Varjas, Michael Wimmer, Anton R. Akhmerov, | Summary: Platforms for creating Majorana quasiparticles rely on superconductivity and breaking of time-reversal symmetry. By studying continuous deformations to known trivial states, we find that the relationship between superconducting pairing and time reversal breaking imposes rigorous bounds […]
