Spin-polarized transport spin-polarized transport
Spin-polarized currents can be manipulated by electric fields, magnetization, or temperature. We study coherent and incoherent spin transport in a variety of systems and geometries. [read more]
  
Spintronic devices spintronic devices
One day spin transistors may perform logic operations in computer processors. We propose and simulate spintronic devices and unravel their working mechanisms. [read more]
  
Electron spins in quantum dots quantum dots
Electron spins are natural qubits. We develop numerical and analytical approaches to describe the electron spins confined in coupled quantum dots and propose realistic quantum information schemes. [read more]
  
Spin relaxation spin relaxation
Unlike charge, spin is not conserved. While spin relaxation has certain universal features, it is unique for each electronic system. [read more]
  
Spin-orbit fields spin-orbit fields
Spin-orbit fields are a collective phenomenon in metals and semiconductors without a center of inversion. We discover the existence of these fields by first-principles methods. [read more]
  
Spintronic materials spintronic materials
Ferromagnetic metals and semiconductors are the material backbones for the electrical generation of spin-polarized currents. We study them in bulk and in heterostructures. [read more]
  
Graphene graphene
The two-dimensional sheet of carbon atoms is full of surprises and challenges. Some are due to the spin-orbit interaction and spin relaxation. [read more]
  
Spin many-body physics
Spin-orbit coupling profoundly changes the Fermi-surface topology of two-dimensional electron gases. We investigate the observable effects of these changes in collective responses of the underlying many-body systems. [read more]
  
Topological Insulators ENB Topologische Isulatoren
The International Doctorate Program is focusing on investigating the fundamental properties and potential applications of topological insulators. Topological insulators are a new state of matter with unique physical characteristics: their surfaces or edges are electrically conducting while the bulk of the material remains insulating. Additionally, the electron spin plays a decisive role for the conduction properties in these surfaces or edges, making topological insulators a very interesting subject for scientific studies. This also means that topological insulators are prime candidates for potential spintronic applications. [read more]
