Evidence for reduced periodic lattice distortion within the Sb-terminated surface layer of the kagome metal CsVSb
Felix Kurtz, Gevin von Witte, Lukas Jehn +8
The discovery of the kagome metal CsVSb sparked broad interest, due to the coexistence of a charge density wave (CDW) phase and possible unconventional superconductivity in…
Optical switching of ferro-rotational charge-density wave states
Wayne Cheng-Wei Huang, Sai Mu, Gevin von Witte +7
Tailored optical excitations can steer a system along non-equilibrium pathways to metastable states with specific structural or electronic properties. The light-induced hidden stat…
Controlled synthesis and characterization of porous silicon nanoparticles for dynamic nuclear polarization
Gevin von Witte, Aaron Himmler, Viivi Hyppönen +9
Si nanoparticles (NPs) have been actively developed as a hyperpolarized magnetic resonance imaging (MRI) contrast agent with an imaging window close to one hour. However, the progr…
Relaxation enhancement by microwave irradiation may limit dynamic nuclear polarization
Gevin von Witte, Aaron Himmler, Sebastian Kozerke +1
Dynamic nuclear polarization enables the hyperpolarization of nuclear spins beyond the thermal-equilibrium Boltzmann distribution. However, it is often unclear why the experimental…
