Superconducting diode from flux biased Josephson junction arrays
Rafael Haenel, Oguzhan Can
We propose a realization of the superconducting diode effect in flux biased superconducting circuits of Josephson junctions. So far the observation of the superconducting diode eff…
Traversable wormhole in coupled SYK models with imbalanced interactions
Rafael Haenel, Sharmistha Sahoo, Timothy H. Hsieh +1
A pair of identical Sachdev-Ye-Kitaev (SYK) models with bilinear coupling forms a quantum dual of a traversable wormhole, with a ground state close to the so called thermofield dou…
Time-resolved optical conductivity and Higgs oscillations in two-band dirty superconductors
Rafael Haenel, Paul Froese, Dirk Manske +1
Recent studies have emphasized the importance of impurity scattering for the optical Higgs response of superconductors. In the dirty limit, an additional paramagnetic coupling of l…
Identification of symmetry-protected topological states on noisy quantum computers
Daniel Azses, Rafael Haenel, Yehuda Naveh +3
Identifying topological properties is a major challenge because, by definition, topological states do not have a local order parameter. While a generic solution to this challenge i…
Zero Bias Conductance Peak in Dirac Semimetal-Superconductor Devices
W. Yu, Rafael Haenel, M. A. Rodriguez +5
Majorana zero modes (MZMs), fundamental building blocks for realizing topological quantum computers, can appear at the interface between a superconductor and a topological material…
Coupled rate-equation hydrodynamic simulation of a Rydberg gas Gaussian ellipsoid: Classical avalanche and evolution to molecular plasma
Rafael Haenel, Edward Grant
An ellipsoidal volume of Rydberg molecules, entrained in a supersonic molecular beam, evolves on a nanosecond timescale to form a strongly coupled ultracold plasma. We present coup…
