Simulating alternating bias assisted annealing of amorphous oxide tunnel junctions
Alexander C. Tyner, Alexander V. Balatsky
Amorphous oxide tunneling barriers, primarily formed from aluminum, represent one of the most widely adopted platforms for superconducting quantum bits (qubits). To overcome challe…
Tailoring Superconductivity with Two-Level Systems
Joshuah T. Heath, Alexander C. Tyner, S. Pamir Alpay +2
We investigate the impact of two-level systems (TLSs) on superconductivity, treating them as soft modes localised in real space. We show that these defects can either enhance or su…
Orbital Inverse Faraday and Cotton-Mouton Effects in Hall Fluids
Gabriel Cardoso, Erlend Syljuåsen, Alexander V. Balatsky
We report two light-induced orbital magnetization effects in quantum Hall (QH) fluids, stemming from their transverse response. The first is a purely transverse contribution to the…
Eight-fold classification of superconducting orders
Alexander V. Balatsky, Saikat Banerjee
We present a symmetry-based classification for superconducting pairing states, organized by the exchange properties of the anomalous correlation function rather than by a specific…
