• Abstract: We demonstrate that spin-dependent electron diffraction is possible for a smooth range of transverse electron momenta in a two-photon Bragg scattering scenario of the Kapitza-Dirac effect. Our analysis is rendered possible by introducing a generalized specification for quantifying spin-dependent diffraction, yielding an optimization problem which is solved by making use of a Newton gradient iteration scheme. With this procedure, we investigate the spin-dependent effect for different transverse electron momenta and different laser polarizations of the standing light wave Kapitza-Dirac scattering. The possibility for using arbitrarily low transverse electron momenta, when setting up a spin-dependent Kapitza-Dirac experiment allows longer interaction times of the electron with the laser and therefore enables less constraining parameters for an implementation of the effect.

• Emerging holonomy in electron spin scattering [0.5461938536945721]
  We develop a method for calculating the scattering matrix of electrons in a one-dimensional coherent conductor connected to two electrodes. In particular, we show that in the high-energy limit, the transmission matrix aligns with the holonomy, reducing to a pure topological form. Our results indicate the possibility of achieving near-perfect spin-flip transmission, with implications for use in spintronic applications.

  In this work, we theoretically investigate the microscopic magneto-optical properties and spin-dependent optical loops. We show that fine interactions, including spin-orbit coupling and spin-spin interaction, are fully characterized to provide versatile qubit functional parameters. This work not only reveals the mechanism underlying the optical spin polarization but also proposes productive avenues for optimizing quantum information processing tasks.

  We present a scalable approach to increase the size of electronic-spin registers. We experimentally realize this approach to demonstrate the detection and coherent control of an unknown electronic spin outside the coherence limit of a central NV. Our work paves the way for engineering larger quantum spin registers with the potential to advance nanoscale sensing, enable correlated noise spectroscopy for error correction, and facilitate the realization of spin-chain quantum wires for quantum communication.
