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…

The role of nuclear spin diffusion in dynamic nuclear polarization of crystalline nanoscale silicon particles
Gevin von Witte, Konstantin Tamarov, Neva Sahin +7
Hyperpolarized nanoparticles (NPs) offer high polarization levels with room temperature relaxation times exceeding half an hour. In this work, we demonstrate that the achievable hy…

Two-electron two-nucleus effective Hamiltonian and the spin diffusion barrier
Gevin von Witte, Sebastian Kozerke, Matthias Ernst
Dynamic nuclear polarization (DNP) involves a polarization transfer from unpaired electrons to hyperfine coupled nuclei and can increase the sensitivity of nuclear magnetic resonan…
