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…
Superconducting singlet-triplet qubits
Anatoliy Lotkov, Maria Spethmann, Daniel Loss
Hybrid devices integrating quantum dots with Josephson junctions are gaining interest because they combine spin-based quantum computing with circuit quantum electrodynamics (circui…
Instabilities of Fermi Liquids with Arbitrary Forward Scattering: Exact Approach
Dmitry Miserev, Joel Hutchinson, Herbert Schoeller +2
In this work, we consider -fold degenerate -dimensional electron gas with spherical Fermi surface and arbitrary forward-scattering density-density interaction transferring sm…
Local and nonlocal STM transport signatures of spin polarization in second order topological superconductors
PaweÅ Szumniak, Daniel Loss, Jelena Klinovaja
We investigate numerically the spin and transport properties of two-dimensional second-order topological superconductors (2D SOTSCs) hosting a pair of Majorana corner states (MCSs)…
Quantum geometrical description of hole spin qubits far away from the -point
Zoltán György, Dmitry Miserev, Jelena Klinovaja +1
Hole spin qubits provide one of the leading platforms for spin-based quantum computing due to their large intrinsic spin-orbit interaction (SOI), which enables fast electrical mani…
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…
