Intrinsic Magnetic (EuIn)As Nanowire Shells with a Unique Crystal Structure
Nano Lett. 22, 8925 - 8931 (2022)

    Inducing magnetism into topological electronic matter is a long-sought goal. It bears the promise to realize novel time-reversal symmetry broken topological electronic states such as the anomalous quantum Hall insulator, axion insulator, and antiferromagnetic topological insulator, each hosting unique boundary modes.



An artificial polariton neuron as a step towards photonic system that mimics
the operation of the human brain
Laser Photonics Rev. 2100660 (2022)

    Scientists from the Institute of Physics, Polish Academy of Sciences, and the Faculty of Physics at the University of Warsaw used photons to create a spiking neuron, i.e. the basic element of the future photonic neural network processor. The so-called neuromorphic devices, i.e. systems that imitate the behaviour of the biological brain, which researchers are working on, are the future of artificial intelligence, as they allow for much faster and more effective information processing. We can read about the results of their work in the latest "Laser and Photonics Reviews.



The optical Stern-Gerlach Deflection and Young s experiment in the reciprocal space
Phys. Rev. Lett. 127, 190401 (2021)

    Scientists for the first time demonstrated Young's experiment for photons in the reciprocal space. Spin patterns corresponding to the persistent spin helix and the Stern-Gerlach experiment are realized in an optically anisotropic liquid crystal microcavity. By applying electric voltage across the microcavity, the liquid crystal molecules inside could be rotated in such a way that the light passing through the cavity was forced to change its internal state into right- and left-handed circular polarized components.
