    • Emergent symmetries and phases in quantum spin chains coupled to a Kuramoto model 

      Bastidas, V. M. (American Physical Society (APS), 2025-10-08)
      Floquet theory is a widely used framework to describe the dynamics of periodically driven quantum systems. The usual scenario to describe such systems is to consider the effect of an external control with a definite period ...
    • Relativistic electrodynamics with a universal length scale 

      Pedergnana, Tiemo; Kogelbauer, Florian (American Physical Society (APS), 2025-08-20)
      We derive the analogues of the Dirac and Pauli equations from a spatially fourth-order Klein-Gordon equation with a universal length scale. Starting from a singularly perturbed variant of Maxwell's equations, we deduce a ...
    • The Imminent Data Desert: The Future of Stratospheric Monitoring in a Rapidly Changing World 

      Salawitch, Ross J; Smith, Jessica B; Selkirk, Henry; Wargan, Krzysztof; Chipperfield, Martyn P; e.a. (American Meteorological Society, 2025-03-01)
      The Atmospheric Chemistry Experiment–Fourier Transform Spectrometer (ACE-FTS) on SCISAT-1 and Microwave Limb Sounder (MLS) on NASA’s Aura satellite have contributed significantly to understanding the impacts of human ...
