Author(s): Daniel Greve, Giorgio Lovato, Tobias Frohoff-Hülsmann, and Uwe Thiele Employing a two-species Cahn-Hilliard model with nonreciprocal interactions, we show that the interplay of nonreciprocity and conservation laws results in the robust coexistence of uniform stationary and oscillatory phases as well as of uniform and crystalline phases. For nonequilibrium models with … [Phys. Rev. Lett. 134, 018303] Published Wed Jan 08, 2025

Author(s): D. J. G. Pearce, C. Thibault, Q. Chaboche, and C. Blanch-Mercader Orientational order is a common feature of many biological and synthetic materials. Topological defects are discontinuities in this order that are often coupled to geometric features of the materials. Here, we study the equilibrium shapes of fluid membranes featuring a $+1$ topological defect as a m… [Phys. Rev. Lett. 134, 018402] Published Tue Jan 07, 2025

Author(s): Yikuan Zhang, Qi Ouyang, and Yuhai Tu Although optimal control (OC) has been studied in stochastic thermodynamics for systems with continuous state variables, less is known in systems with discrete state variables, such as chemical reaction networks (CRNs). Here, we develop a general theoretical framework to study OC of CRNs for changin… [Phys. Rev. Lett. 134, 018001] Published Mon Jan 06, 2025

Author(s): Monoj Adhikari, Rishabh Sharma, and Smarajit Karmakar We investigate the memory effects in cyclically deformed amorphous solids through computer simulations. Applying oscillatory shear deformations in all orthogonal directions during encoding creates fault-tolerant memories that are agnostic to the reading direction. Our extensive system size analysis … [Phys. Rev. Lett. 134, 018202] Published Mon Jan 06, 2025

Author(s): Xichen Chao, Katherine Skipper, C. Patrick Royall, Silke Henkes, and Tanniemola B. Liverpool We study an intriguing new type of self-assembled active colloidal polymer system in 3D. It is obtained from a suspension of Janus particles in an electric field that induces parallel dipoles in the particles as well as self-propulsion in the plane perpendicular to the field. At low volume fractions… [Phys. Rev. Lett. 134, 018302] Published...

Author(s): Valentin Schmutz, Johanni Brea, and Wulfram Gerstner Can spiking neural networks (SNNs) approximate the dynamics of recurrent neural networks? Arguments in classical mean-field theory based on laws of large numbers provide a positive answer when each neuron in the network has many “duplicates”, i.e., other neurons with almost perfectly correlated inpu… [Phys.

Kamien, and Emmanuelle Lacaze A combination of nonlinear theory and x-ray diffraction experiments of smectic liquid crystals reveals the need for a nonlinear energy term to correctly...
