Author(s): Pasquale Digregorio, Ignacio Pagonabarraga, and Francisco Vega Reyes We show that systematic particle rotations in a fluid composed of disk-shaped spinners can spontaneously lead to phase separation. The phenomenon arises out of a homogeneous and hydrostatic stationary state, due to a pressure feedback mechanism that increases local density fluctuations. We show how … [Phys. Rev.

Author(s): Ivar S. Haugerud, Hidde D. Vuijk, Job Boekhoven, and Christoph A. Weber In the field of biomolecular condensates and synthetic systems, it is an open question whether liquid droplets can undergo self-sustained oscillations of formation and dissolution. To unravel the minimal physicochemical prerequisite for such droplet oscillations, we present a simple model composed o… [Phys. Rev. Lett. 136, 218401] Published Wed May 27, 2026

Author(s): H. E. Read, G. Risso, A. Djellouli, K. Bertoldi, and A. Lazarus Parametric instabilities are a known feature of periodically driven dynamic systems; at particular frequencies and amplitudes of the driving modulation, the system’s quasiperiodic response undergoes a frequency lock-in, leading to a periodically unstable response. Here, we demonstrate an analogous p… [Phys. Rev. Lett. 136, 208201] Published Mon May 18, 2026

Author(s): Jacopo Romano, Martin Kjøllesdal Johnsrud, Benoît Mahault, and Ramin Golestanian We study the behavior of catalytically active droplets in multicomponent conserved mixtures affected by noise. Working in the thin interface limit, we analytically determine the state diagram of the system, characterized by multiple dynamical regimes, and verify our findings using numerical simulati… [Phys.

Author(s): Jacob Knight, Farid Kaveh, and Gunnar Pruessner Entropy production distinguishes equilibrium from nonequilibrium. Calculating the entropy production rate (EPR) is challenging in systems where some degrees of freedom cannot be observed. Here we introduce a perturbative framework to calculate the time irreversibility of an active particle with hidd… [Phys. Rev. Lett. 136, 198302] Published Fri May 15, 2026

Author(s): Riccardo Rossetto, Marcel Ernst, and David Zwicker Biological membranes often exhibit heterogeneous protein patterns, which cells control. Strong patterns, like the polarity spot in budding yeast, can be described as surface condensates, formed by physical interactions between constituents. However, it is unclear how these interactions affect the ma… [Phys. Rev. Lett. 136, 198401] Published Fri May 15, 2026
