Electron Spin Polarization as a Predictor of Chiroptical Activity in Helical Molecules
Solmar Varela, Rafael Gutierrez, Gianaurelio Cuniberti +2
Chiral structures, breaking spatial inversion symmetry, exhibit non-zero chiroptical activity (COA) due to the interaction between their electric and magnetic responses under exter…
Hierarchies of Hofstadter butterflies in 2D covalent-organic frameworks
David Bodesheim, Robert Biele, Gianaurelio Cuniberti
The Hofstadter butterfly is one of the first and most fascinating examples of the fractal and self-similar quantum nature of free electrons in a lattice pierced by a perpendicular…
Atomistic Modelling of Energy Dissipation in Nanoscale Gears
Huang-Hsiang Lin, Alexander Croy, Rafael Gutierrez +1
Molecule- and solid-state gears build the elementary constituents of nanoscale mechanical machineries. Recent experimental advances in fabrication technologies in the field have st…
The contribution of intermolecular spin interactions to the London dispersion forces between chiral molecules
M. Geyer, R. Gutierrez, V. Mujica +3
Dispersion interactions are one of the components of van der Waals (vdW) forces, which play a key role in the understanding of intermolecular interactions in many physical, chemica…
Effective Hamiltonian model for helically constrained quantum systems within adiabatic perturbation theory: application to the Chirality-Induced Spin Selectivity (CISS) Effect
Matthias Geyer, Rafael Gutierrez, Gianaurelio Cuniberti
The chirality-induced spin selectivity (CISS) effect has been confirmed experimentally for a large class of organic molecules. Adequately modeling the effect remains a challenging…
Spin-polarized electron transmission in DNA-like systems
Miguel A. Sierra, David Sanchez, Rafael Gutierrez +3
The helical distribution of the electronic density in chiral molecules, such as DNA and bacteriorhodopsin, has been suggested to induce a spin-orbit coupling interaction that may l…
