Equilibration in closed quantum systems: Application to spin qubits
Daniel Hetterich, Moritz Fuchs, Björn Trauzettel
We study an observable-based notion of equilibration and its application to realistic systems like spin qubits in quantum dots. On the basis of the so-called distinguishability, we…
Thermal electron spin flip in quantum dots
Moritz Fuchs, Felix Krauß, Daniel Hetterich +1
We study a thermally induced spin flip of an electron spin located in a semiconductor quantum dot. This interesting effect arises from an intriguing interplay between the Zeeman co…
Ultra long spin decoherence times in graphene quantum dots with a small number of nuclear spins
Moritz Fuchs, John Schliemann, Björn Trauzettel
We study the dynamics of an electron spin in a graphene quantum dot, which is interacting with a bath of less than ten nuclear spins via the anisotropic hyperfine interaction. Due…
Spin decoherence in graphene quantum dots due to hyperfine interaction
Moritz Fuchs, Valentin Rychkov, Björn Trauzettel
Carbon based systems are prominent candidates for a solid-state spin-qubit due to weak spin-orbit and hyperfine interactions in combination with a low natural abundance of spin car…
