Nuclear magnetic resonance (NMR) and electron spin resonance spectroscopies

Here, the research focus is on unconventional multi-band superconductivity with complex order parameters and coupling mechanisms and on systems with strong spin orbit coupling (SOC), such as Kitaev honeycomb lattices and non-centrosymmetric helimagnets hosting a new form of magnetically ordered state, the Skyrmion lattice. Spin excitations in ferromagnetic critical 3d-electron systems as well as linear d-bands in Dirac- and Weyl-fermion systems are other important topics in solid state NMR.
