  • Hybridized Soliton Lasing in Coupled Semiconductor Lasers

    Author(s): Theodore P. Letsou, Dmitry Kazakov, Pawan Ratra, Lorenzo L. Columbo, Massimo Brambilla, Franco Prati, Cristina Rimoldi, Sandro Dal Cin, Nikola Opačak, Henry O. Everitt, Marco Piccardo, Benedikt Schwarz, and Federico Capasso An experiment demonstrates that a chip-scale coupled laser system consisting of a pair of coupled semiconductor ring lasers can exhibit complex optical states impossible to achieve in a single waveguide laser. ...

  • Planar Hall Effect in Quasi-Two-Dimensional Materials

    Author(s): Koushik Ghorai, Sunit Das, Harsh Varshney, and Amit Agarwal Stacked bilayer graphene can demonstrate a 2D planar Hall effect due to factors related to Berry curvature, orbital magnetic moments, and broken symmetries. [Phys. Rev. Lett. 134, 026301] Published Mon Jan 13, 2025

  • Smooth Exact Gradient Descent Learning in Spiking Neural Networks

    Author(s): Christian Klos and Raoul-Martin Memmesheimer By incorporating electrical pulses with shapes similar to those of the spikes from biological neurons, researchers improved the ability to train energy-efficient types of neural networks.
