Fischer, and Daniel de las Heras Using computer simulations and experiments, we demonstrate a mechanism for simultaneous size-specific control over the trajectories of isotropic colloidal particles. Magnetic microparticles of different diameters suspended above a periodic magnetic film...

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): Nathan McLane, LeAnh Duckett, and Leah G. Dodson The transitions of hydrogen molecules embedded in a crystal depend on the surroundings—a behavior that could be used to tailor molecular quantum dynamics. [Phys. Rev. Lett. 136, 178002] Published Wed Apr 29, 2026

Author(s): William T. Simpkins, Matthew G. Hennessy, and Matteo Taffetani Snap through occurs in elastic structures when a stable equilibrium configuration becomes unstable, resulting in rapid motion towards a new and distinct stable state. While static analyses of snap through are well documented, the dynamics of snap through remain underexplored, particularly in structu… [Phys. Rev. Lett. 136, 178202] Published Wed Apr 29, 2026

Author(s): Jonathan Bauermann, Giacomo Bartolucci, and Artemy Kolchinsky We develop a method for studying chemical oscillators in the presence of phase separation. Specifically, we define a dynamics at phase equilibrium by imposing timescale separation between slow reactions and fast diffusion. We show that colocalization of components can alter oscillator frequency and … [Phys. Rev. Lett. 136, 178001] Published Tue Apr 28, 2026

Author(s): José Ruiz-Franco and Alberto Fernandez-Nieves Structure most frequently constrains material behavior, resulting in the coupling between structural and dynamical properties. Using numerical simulations, we show that single-particle elasticity can cause the breakdown of this coupling, enabling liquidlike dynamics within crystalline configurations… [Phys. Rev.
