Skyrmion Qubits: A New Class of Quantum Logic Elements Based on Nanoscale Magnetization
Christina Psaroudaki, Christos Panagopoulos
We introduce a new class of primitive building blocks for realizing quantum logic elements based on nanoscale magnetization textures called skyrmions. In a skyrmion qubit, informat…
Curvature-Induced Skyrmion Mass
Alexander Pavlis, Christina Psaroudaki
We investigate the propagation of magnetic skyrmions on elastically deformable geometries by employing imaginary time quantum field theory methods. We demonstrate that the Euclidea…
Spin Wave Radiation by a Topological Charge Dipole
Sebastian A. Diaz, Tomoki Hirosawa, Daniel Loss +1
The use of spin waves (SWs) as data carriers in spintronic and magnonic logic devices offers operation at low power consumption, free of Joule heating. Nevertheless, the controlled…
Enhancement of magnetization plateaus in low dimensional spin systems
Alexandros Metavitsiadis, Christina Psaroudaki, Wolfram Brenig
We study the low-energy properties and, in particular, the magnetization process of a spin-1/2 Heisenberg sawtooth and frustrated chain (also known as zig-zag ladder) wit…
Quantum Depinning of a Magnetic Skyrmion
Christina Psaroudaki, Daniel Loss
We investigate the quantum depinning of a weakly driven skyrmion out of an impurity potential in a mesoscopic magnetic insulator. For small barrier height, the Magnus force dynamic…
Quantum Brownian Motion of a Magnetic Skyrmion
Christina Psaroudaki, Pavel Aseev, Daniel Loss
Within a microscopic theory, we study the quantum Brownian motion of a skyrmion in a magnetic insulator coupled to a bath of magnon-like quantum excitations. The intrinsic skyrmion…
