Quantum Dynamics of Skyrmions in Chiral Magnets
Christina Psaroudaki, Silas Hoffman, Jelena Klinovaja +1
We study the quantum propagation of a Skyrmion in chiral magnetic insulators by generalizing the micromagnetic equations of motion to a finite-temperature path integral formalism,…
Dynamical Shiba states by precessing magnetic moments in an s-wave superconductor
V. Kaladzhyan, S. Hoffman, M. Trif
We study theoretically the dynamics of a Shiba state forming around precessing classical spin in an s-wave superconductor. Utilizing a rotating wave description for the precessing…
Detecting Topological Superconductivity with Josephson Junctions
Constantin Schrade, Silas Hoffman, Daniel Loss
The interplay of superconductivity, magnetic fields, and spin-orbit interaction lies at the heart of topological superconductivity. Remarkably, the recent experimental discovery of…
Universal Quantum Computation with Hybrid Spin-Majorana Qubits
Silas Hoffman, Constantin Schrade, Jelena Klinovaja +1
We theoretically propose a set of universal quantum gates acting on a hybrid qubit formed by coupling a quantum dot spin qubit and Majorana fermion qubit. First, we consider a quan…
Topological Phases of Inhomogeneous Superconductivity
Silas Hoffman, Jelena Klinovaja, Daniel Loss
We theoretically consider the effect of a spatially periodic modulation of the superconducting order parameter on the formation of Majorana fermions induced by a one-dimensional sy…
