Lay Summary (English)

Lead
Lay summary
My research interests include many aspects of the theory of condensed matter systems with a particular focus on spin-dependent and phase coherent phenomena (‘mesoscopics’) in semiconducting nanostructures and molecular magnets. A major portion of my current research involves the theory of spin dynamics, spin coherence, spintronics in two-dimensional electron gases, and spin-related phenomena in semiconducting quantum dots--artificial atoms and molecules. Much of this work is naturally linked to quantum information processing (QIP)--quantum computing and quantum communication in solid state systems with focus on spin qubits.
where we made seminal contributions. Our work on QIP belongs to the most cited in the field.My work has laid the foundation for spin-based QIP in nanostructures, attracting wide interest over many years and stimulating My theoretical predictions and proposals have stimulated many further investigations. In particular, there are many experimental programs on spin qubits worldwide which are implementing our theoretical concepts with great success, also confirming numerous predictions which we have made on the fundamental properties of spins in solids.such as T1 times, strong correlationsin coupled quantum dots,Current research includes spin relaxation and decoherence in quantum dots due to spin-orbit and hyperfine interaction; non-Markovian spin dynamics in bosonic and nuclear spin environments; generation and characterization of non-local entanglement with quantum dots, superconductors, Luttinger liquids or Coulomb scattering in interacting 2DEGs; spin currents in magnetic insulators and in semiconductors; spin Hall effect in disordered systems; spin orbit effects in transport and noise; asymmetric quantum shot noise in quantum dots; entanglement transfer from electron spins to photons; QIP with spin qubits in quantum dots and molecular magnets; macroscopic quantum phenomena (spin tunneling and coherence) in molecular and nanoscale magnetism.
