Molecular Hamiltonian learning from setpoint-dependent scanning tunneling spectroscopy
Greta Lupi, Adolfo O. Fumega, Mohammad Amini +3
Molecular quantum magnets adsorbed on surfaces exhibit rich spin and orbital excitations that can be probed by scanning tunneling microscopy with inelastic electron tunneling spect…
Hamiltonian learning quantum magnets with dynamical impurity tomography
Netta Karjalainen, Greta Lupi, Rouven Koch +2
Nanoscale engineered spin systems, ranging from spins on surfaces to nanographenes, provide flexible platforms to realize entangled quantum magnets from a bottom up approach. Howev…
Quasiparticle gap renormalization driven by internal and external screening in a WS device
Chakradhar Sahoo, Yann in 't Veld, Alfred J. H. Jones +11
The electronic band gap of a two-dimensional semiconductor within a device architecture is sensitive to variations in screening properties of adjacent materials in the device and t…
