Parity-Resolved Quantum Capacitance and Quantum Inductance in Topological, Trivial, and Normal Nanowire Interferometers
Viktoriia Pinchenkova, Valerii K. Kozin, Maximilian Hünenberger +2
Quantum-capacitance measurements convert the curvature of a quantum-dot energy in a flux-threaded nanowire loop into fast parity-sensitive signals and, therefore, have become a pro…
From coupled Rabi models to the Potts model
Anatoliy I. Lotkov, Valerii K. Kozin, Denis V. Kurlov +2
We study -symmetric Rabi model that describes a three-level system coupled to two bosonic modes. We derive a mapping of the two-mode Rabi model onto a…
Emergent ac Effect in Nonreciprocal Coupled Condensates
Ji Zou, Valerii K. Kozin, Daniel Loss +1
We report an emergent ac Josephson-like effect arising without external bias, driven by the interplay between nonreciprocity and nonlinearity in coupled condensates. Using a minima…
Schottky anomaly in a cavity-coupled double quantum well
Valerii K. Kozin, Dmitry Miserev, Daniel Loss +1
We present a theoretical study of a mesoscopic two-dimensional electron gas confined in a double quantum well that is coupled to a uniform quasi-static cavity mode via fluctuations…
Cat states in one- and two-mode Rabi models
Anatoliy I. Lotkov, Denis V. Kurlov, Valerii K. Kozin +2
We investigate one- and two-mode variants of the -symmetric quantum Rabi model, which describe the interaction of a qutrit with one or two bosonic modes and are direc…
Cavity-enhanced superconductivity via band engineering
Valerii K. Kozin, Even Thingstad, Daniel Loss +1
We consider a two-dimensional electron gas interacting with a quantized cavity mode. We find that the coupling between the electrons and the photons in the cavity enhances the supe…
