Even on one-lane paths, the ants tactfully manage a bidirectional flow: An informed individual (termed leader) guides one nest mate (termed follower) to a new optimal nest, and then returns to recruit additional followers (one follower at a time). We propose that encounters between the ants moving in opposite directions can be modeled within the framework of game theory, leading to an understanding of the mechanism behind observed behaviors. Our experiments reveal that, upon encountering a tandem pair (a leader and its follower) on a narrow path, the returning leader reverses her direction and proceeds toward the new nest again. This observed behavior is consistent with game-theoretic predictions, provided the assumption of perfect rationality is relaxed in favor of bounded rationality-specifically, procedural rationality, i.e., an agent explores all her actions independently before adopting a particular action. In other words, the experimental outcomes are consistent with sampling equilibrium-the game theoretic equilibrium realized when procedural rational players are pitted against one another-but not with Nash equilibrium. Our work, which strives to bring the essence of behavioral game theory into the world of ants, demonstrates sampling equilibrium in a scenario without human players, extending the concept beyond its traditional application to human decision-making.","PeriodicalId":20085,"journal":{"name":"Physical review.

This study is motivated by the recent radar detection of liquid water underneath the Martian South Pole. We explore the supercooled regime for salt concentrations up to 24.4 wt %. In the region of mild supercooling we analyze the water oxygen self-intermediate scattering functions. Our results show that the relaxation dynamics of water is well described by the mode coupling structural relaxation in this region. Upon further cooling, a fragile-to-strong crossover is observed for all investigated concentrations. Below the crossover, activated processes maintain the ergodicity. Notably, the addition of magnesium perchlorate induces a downward shift in both the mode coupling temperature and the fragile-to-strong crossover temperature. This combined effect extends the range of existence of the supercooled liquid regime to lower temperatures compared to bulk water. These findings support the hypothesis that perchlorate aqueous solutions can persist in a thermodynamically metastable liquid state at the low-temperature conditions of the Martian subsurface.","PeriodicalId":20085,"journal":{"name":"Physical review.

Recent arguments based on thermodynamics and critical scalings have revived the proposal that the SCF constitutes an intermediate state of matter, separated from the liquid and gas by two supercritical boundaries, the L^{±} lines. However, until now, the nature of the supercritical state and the physical signatures of these boundaries have remained elusive. Here, we demonstrate that the SCF is characterized by distinct structural, transport, and dynamical behavior. Specifically, the spatial arrangement of particles-captured by the radial distribution function-as well as the diffusion coefficient, shear viscosity, and velocity autocorrelation function in the SCF regime are qualitatively different from those in both the liquid and gas states and exhibit physical signatures upon crossing the L^{±} lines. Our theoretical predictions are supported by molecular dynamics simulations of argon and are further supported by existing experimental evidence. These results provide a clear physical foundation for a refined phase diagram of matter in the supercritical region, comprising three distinct states-gas, supercritical fluid, and liquid-separated by two crossover boundaries obeying universal scaling laws.","PeriodicalId":20085,"journal":{"name":"Physical review.

In the brain, information is thought to be stored in synaptic connections between neurons whose weights change in response to pre- and postsynaptic action potentials, or spikes, according to specific plasticity rules. To date, most models of synaptic plasticity are derived from in vitro studies in which spike times are under precise experimental control, but whether these models generalize to in vivo regimes of high spike time variability is not known. To shed light on this problem theoretically, here I estimate the mutual information between Poisson spike trains in a network of neurons and the synaptic weight updates they trigger via different plasticity rules. Although most synaptic plasticity models propose correlation- or coincidence-based rules based on the measurement of pre- and postsynaptic spike times, I show that such rules do not always maximize information storage. In the biologically important, energy-efficient operating regime of low firing rates and sparse plasticity, rules that simply count pre- and/or postsynaptic spikes in fact store more information per synapse than spike-timing-dependent rules that measure coincidence events. In such regimes, spikes are more common than coincidences hence better able to transmit information into synaptic weights. It may in turn be advantageous to encode information to be stored as spike counts, or time averages, rather than correlations. The theory suggests a normative account for recently discovered noncanonical hippocampal plasticity rules in vivo and predicts that spike-timing-dependent rules will be preferentially active in neural circuits operating at higher firing rates.","PeriodicalId":20085,"journal":{"name":"Physical review.

We study two tessellation models, Dichotomous Gilbert (DG) and Hierarchical Gilbert (HG), which implement different hierarchical splitting rules. Both models generate fragment-area distributions well described by a truncated power-law function, namely a power multiplied by a stretched exponential function or generalized Gamma function. The Gilbert's classic tessellation model gives rise, on the contrary, to a simple exponential distribution. To further characterize the underling complexity, we perform a multifractal analysis of the fragment areas. The results demonstrate that Gilbert's hierarchical fragmentation reveals a multifractal scaling.","PeriodicalId":20085,"journal":{"name":"Physical review.

While significant progress has been made in understanding transport phenomena in quantum systems, methods for optimizing transport properties remain limited, particularly in complex quantum networks. Building on recent advances in classical network optimization via the generalized Doob transform, we introduce a method that extends this approach to quantum networks. Our framework leverages a single diagonalization of the system generator to efficiently tailor both the Hamiltonian and dissipative contributions, optimizing transport observables such as currents and activities. We demonstrate the method's effectiveness through extensive numerical explorations, showing that optimal performance arises from nontrivial modifications to both coherent and incoherent dynamics. We also assess the robustness of the optimization under constraints that preserve specific physical features, such as fixed dissipative structures and input-output interactions. Finally, we discuss the connection between optimized transport and centrosymmetry, highlighting the relevance of this property for enhanced transport efficiency in quantum systems.","PeriodicalId":20085,"journal":{"name":"Physical review.

While critical-state shear strength is widely reported to be insensitive to particle size distribution (PSD) in assemblies of grains sharing a common shape, grain shape itself has a strong impact on strength, with angular particles generally producing higher resistance than rounded ones. Many natural and industrial granular materials, however, combine broad size distributions with significant variability in particle shape, often correlated with particle size. Whether the classical PSD-insensitivity of shear strength still holds when particle shape varies across size classes remains largely unexplored. Here, we present a systematic experimental investigation of sheared granular assemblies composed of injection-molded particles with controlled sizes and shapes. Mono, bi, and polyshaped mixtures built from six characteristic grain geometries are tested under triaxial compression. We show that the classical PSD-insensitivity of critical-state shear strength breaks down when particle shape becomes size dependent. For a given PSD, assemblies with angular small grains and rounded large grains exhibit significantly higher shear strength than those with the opposite size-shape arrangement. This behavior persists over a wide range of PSDs and can be explained by enhanced geometrical interlocking promoted by angular small particles filling the voids between larger grains.","PeriodicalId":20085,"journal":{"name":"Physical review.
