Same-spin Andreev reflections in the quantum Hall regime: the role of loss
Chun-Chia Chen, Jordan T. McCourt, John Chiles +7
The interfaces of superconductors and topological materials hold promise for realizing exotic states and excitations. An important example is provided by the chiral Andreev edge st…
Quantum Hall Andreev Conversion in Graphene Nanostructures
Alexey Bondarev, William H. Klein, Harold U. Baranger
We study Andreev conversion in clean nanostructures containing an interface between graphene in the quantum Hall (QH) state and a superconductor, focusing on the lowest Landau leve…
Transparent Graphene-Superconductor Interfaces: Quantum Hall and Zero Field Regimes
Alexey Bondarev, Gu Zhang, Harold U. Baranger
We study clean, edge-contacted graphene/superconductor interfaces in both the quantum Hall (QH) and zero field regimes. We find that Andreev reflection is substantially stronger th…
Conductance of a Dissipative Quantum Dot: Nonequilibrium Crossover Near a Non-Fermi-Liquid Quantum Critical Point
Gu Zhang, E. Novais, Harold U. Baranger
We find the nonlinear conductance of a dissipative resonant level in the nonequilibrium steady state near its quantum critical point. The system consists of a spin-polarized quantu…
Interference of chiral Andreev edge states
Lingfei Zhao, Ethan G. Arnault, Alexey Bondarev +9
The search for topological excitations such as Majorana fermions has spurred interest in the boundaries between distinct quantum states. Here, we explore an interface between two p…
Particle Production in Ultra-Strong Coupling Waveguide QED
Nicolas Gheeraert, Xin H. H. Zhang, Théo Sépulcre +4
Understanding large-scale interacting quantum matter requires dealing with the huge number of quanta that are produced by scattering even a few particles against a complex quantum…
