  • Infinite Berry Curvature of Weyl Fermi Arcs

    Author(s): Dennis Wawrzik, Jhih-Shih You, Jorge I. Facio, Jeroen van den Brink, and Inti Sodemann A divergence of Berry curvature occurring over an entire line in the surface momentum space of Weyl semimetals growing as the inverse distance square to such line, opens the possibility of finding a variety of enhanced Berry-curvature-driven physical effects. [Phys. Rev. Lett. 127, 056601] Published Fri Jul 30, 2021

  • Bell Nonlocality Is Not Sufficient for the Security of Standard Device-Independent Quantum Key Distribution Protocols

    Author(s): Máté Farkas, Maria Balanzó-Juandó, Karol Łukanowski, Jan Kołodyński, and Antonio Acín Bell nonlocality is insufficient to ensure the security of a type of secure quantum-communications protocol known as DI-QKD. [Phys. Rev. Lett. 127, 050503] Published Thu Jul 29, 2021

  • Thermodynamic Phase Transition in Magnetic Reconnection

    Author(s): J. Jara-Almonte and H. Ji Fully kinetic plasma simulations in combination with concepts from condensed matter physics, show that the transition from collisional (Sweet-Parker) reconnection to collisionless (Hall) reconnection may be viewed as a thermodynamic phase transition.
