Author(s): Zhen Cao et al. (LHAASO Collaboration) The observation of ultrahigh-energy radiation from a binary star system suggests that such “gamma-ray binaries” could be significant contributors to the cosmic-ray spectrum. [Phys. Rev. Lett. 136, 181001] Published Wed May 06, 2026

Author(s): Marzena Rams-Baron, Alfred Błażytko, Riccardo Casalini, and Marian Paluch The long-standing Arrhenius paradox in molecular glasses is resolved by showing that activation energy decreases linearly with temperature as a consequence of density-driven variations of the barrier.

Author(s): Albert Nazeeri, Chiara Brandenstein, Chengjie Jia, Lorenzo Magrini, and Giorgio Gratta Coupling a film of enriched 57Fe to a surface acoustic wave produces a comb of absorption sidebands in the Mossbauer spectrum, consistent with coherent phase modulation of the nuclear transition.

Fedorov The deterministic quantum teleportation of microwave coherent states between two spatially-separated dilution refrigerators connected via a superconducting channel operating at temperatures up to 4 Kelvin demonstrates the experimental feasibility of quantum communication over a thermal microwave network.

Author(s): Philippe Corboz, Yining Zhang, Boris Ponsioen, and Frédéric Mila High-precision tensor network calculations in the 2D thermodynamic limit reveal a narrow quantum spin liquid phase, consistent with previous studies, but based on variational states significantly closer to the exact ground state in the thermodynamic limit.
