Cavity-mediated coherent coupling between distant quantum dots
Giorgio Nicolí, Michael Sven Ferguson, Clemens Rössler +7
Scalable architectures for quantum information technologies require to selectively couple long-distance qubits while suppressing environmental noise and cross-talk. In semiconducto…
Non-linear and dot-dependent Zeeman splitting in GaAs/AlGaAs quantum dot arrays

Electrostatic confinement in semiconductors provides a flexible platform for the emulation of interacting electrons in a two-dimensional lattice, including in the presence of gauge…
Edge channel confinement in a bilayer graphene -- quantum dot
Hiske Overweg, Peter Rickhaus, Marius Eich +6
We combine electrostatic and magnetic confinement to define a quantum dot in bilayer graphene. The employed geometry couples -doped reservoirs to a -doped dot. At magnetic fi…

We report the fabrication of electrostatically defined nanostructures in encapsulated bilayer graphene, with leakage resistances below depletion gates as high as G.…
Long-range spin-coherence in a strongly-coupled all electronic dot-cavity system
Michael Sven Ferguson, David Oehri, Clemens Rössler +4
We present a theoretical analysis of spin-coherent electronic transport across a mesoscopic dot-cavity system. Such spin-coherent transport has been recently demonstrated in an exp…
High pressure Raman study of the quantum magnet (CHN)CuCl

Magnetic and lattice excitations in the quantum antiferromagnet (CHN)CuCl (PHCC) are studied across two pressure-induced phase transition at $P_c=4.3~\mathrm…
Time- and spatially-resolved magnetization dynamics driven by spin-orbit torques
Manuel Baumgartner, Kevin Garello, Johannes Mendil +11
Current-induced spin-orbit torques (SOTs) represent one of the most effective ways to manipulate the magnetization in spintronic devices. The orthogonal torque-magnetization geomet…
A levitated nanoparticle as a classical two-level atom
