• Abstract: We use the Wick-rotated time-dependent supersymmetry to construct models of two-dimensional Dirac fermions in presence of an electrostatic grating. We show that there appears omnidirectional perfect transmission through the grating at specific energy. Additionally to being transparent for incoming fermions, the grating hosts strongly localized states.

  We show how photon-mediated interactions give rise to a plaquette-ordered bond pattern in the atomic ground state. The pattern opens a non-trivial topological gap in 2D, resulting in a higher-order topological phase hosting corner states.

  Electrical control of spins at the nanoscale offers architectural advantages in spintronics.

E-field sensitivities reported so far are rather weak, prompting the question of how to design molecules with stronger spin-electric couplings.
