Short presentation

The research group of Prof. Peter Oppeneer focuses on several topics in theoretical condensed matter theory. Our main topics include development of theory for femtosecond magnetism, ultrafast spin and orbital currents, theory for out-of-equilibrium magnon and phonon dynamics, theory of unconventional forms of superconductivity, and ab initio theory for multipolar and hidden order parameters, and orbitronics, as well as computational theory for molecular spintronics and spin-crossover materials.

Keywords

Biography

The research group of Prof. Peter Oppeneer focuses on several topics in theoretical condensed matter theory. Our main topics include development of theory for femtosecond magnetism, theory for out-of-equilibrium phonon and magnon dynamics, theory for ultrafast spin and orbital currents, ab initio theory for unconventional forms of superconductivity and for multipolar and hidden order parameters, as well as computational theory for molecular spintronics and spin-crossover materials. Specifically, we address femtosecond coherent light-induced magnetic processes, such as ultrafast demagnetization, magnetization switching and ultrafast light imparted magnetization. We develop theory to describe ultrafast spin dissipation channels, such as superdiffusion and Elliott-Yafet electron-phonon spin-flip scattering, and we develop computer codes for numerical simulations of these processes in real materials. We also perform ab initio studies of unconventional forms of superconductivity in real materials, as odd-frequency and d-wave superconductivity, using our home-made self-consistent multiband Eliashberg code. Another area of our interest is theory of hidden order and multipolar magnetic order, in correlated materials as URu2Si2 and UO2 and NpO2. Other strongly correlated electron systems we have investigated with our own dynamical mean field theory (DMFT) code. Our aim is to combine advancement of analytical theory hand-in-hand with development of numerical simulation codes.
