This study reveals that filamentous *E. coli* induced by sub-lethal antibiotics exhibit distinct swimming behaviors in low-Reynolds number flows, where motile cells undergo a combination of rigid body rotation and chiral reorientation leading to irregular "wiggling" and wall-directed rheotaxis, while non-motile cells behave as passive rigid rods following streamlines.
This paper proposes a minimal model demonstrating that entropy maximization of spacers induces an attractive force between stickers, leading to sticker clustering and a slow, glassy relaxation process that explains the long-term aging and solidification of biomolecular condensates.
This paper proposes and analyzes a simple mathematical model describing how active and passive particles connected by a linear spring exhibit distinct straight, circular, and slalom motions, with theoretical analysis confirming a bifurcation between straight and circular trajectories driven by the magnitude of self-propulsion.
This paper introduces the MASBot robotic platform to experimentally demonstrate a unified phase diagram of nonreciprocal active matter, revealing continuous transitions between odd elastic, odd viscous, and chiral active gas phases while establishing a blueprint for programmable robotic swarms.
This paper extends a hard-core-free functional renormalization group method to three-dimensional Lennard-Jones liquids, demonstrating through numerical calculations that it achieves accuracy comparable to modern integral-equation theories while maintaining superior thermodynamic consistency.
This study utilizes molecular dynamics simulations to demonstrate that the capillary filling dynamics and post-imbibition relaxation of star polymer melts are profoundly governed by their topology, where arm length and functionality dictate deviations from the Lucas-Washburn equation, induce arm orientation and disentanglement, and significantly enhance adsorption and friction effects.
This paper reports the first experimental observation of a macroscopic continuous spacetime crystal formed by active granular disks, revealing a unique three-stage melting process where spatial and temporal orders decay via distinct mechanisms, thereby demonstrating the decoupling of spontaneous symmetry breaking in space and time.
This paper presents a physics-based pore-network model for yield-stress fluid flow in disordered porous media that accurately captures nonlinear transport and channelization by deriving pressure-flow relations from pore-scale mechanics, revealing that near-yield pressure losses are governed by constriction statistics rather than obstacle-scale length.
Using particle-based simulations, this study demonstrates that self-propulsion in active, non-Brownian suspensions can counteract friction-mediated shear thickening to induce a tunable "dethickening" effect, which follows a universal scaling framework based on dimensionless active stress.
Using molecular dynamics simulations, this study reveals that cylindrical confinement induces a two-stage collapse of homopolymers from a good to a poor solvent—characterized by the formation of pearl-necklace clusters followed by their coalescence into a spherical globule—wherein the relaxation dynamics and activation energies exhibit distinct dependencies on confinement radius and temperature, despite a universal power law governing cluster growth at fixed confinement.
This paper reviews deterministic and stochastic network-level models to explain how Arrhenius-like temperature dependencies in individual biochemical reactions transform into complex emergent system behaviors, such as non-Arrhenius scaling and thermal limits, thereby bridging empirical temperature response curves with the molecular organization of biological systems.
This review article surveys phenomenological and microscopic models used to describe the complex, non-Arrhenius temperature responses of biological systems across various scales, defining key operational metrics like optimal temperatures and thermal limits while setting the stage for a subsequent discussion on how system-level curves emerge from interacting reactions.
This study demonstrates that the parameter-free Random Barrier Model outperforms the von Schweidler law in fitting the inherent dynamics of a viscous ternary Lennard-Jones liquid and accurately predicting its diffusion coefficient, despite the model's unrealistic assumption of identical energy minima.
This paper presents an energetics-based mathematical model for the diffusiophoretic motion of a deformable droplet on a liquid surface, deriving time-evolution equations for translation and elliptic deformation to identify three stable states and analyze the transitions between them.
This paper numerically investigates how external magnetic fields influence the long-range transport of large polarons (solitons) in discrete quasi-one-dimensional systems, demonstrating that the effect depends on both field strength and specific system parameters that define soliton properties, while also examining polarons generated by donor complexes.
This paper provides a rigorous theoretical justification for the noise-cancellation algorithm in interacting Brownian systems by proving that cross-correlations vanish in thermal equilibrium—rendering the method exact—while demonstrating that finite cross-correlations in nonequilibrium systems serve as a distinct fingerprint of non-equilibrium physics requiring specific corrections.
This paper proposes and optimizes a magnetically driven elastic microswimmer that achieves autonomous, nonreciprocal propulsion through hysteretic collapse of its segments, enabling the simultaneous independent control of multiple microrobots via a single oscillating magnetic field for potential medical applications.
This study presents a glucose oxidase-embedded hydrogel that utilizes enzymatic pH waves to drive autonomous, energy-dependent spatiotemporal stiffening, revealing that mechanical transduction lags behind chemical propagation and establishing design principles for adaptive soft materials.
This paper presents a minimal synthetic framework for force-responsive hydrogels based on reversible ring-forming polymers, which, as demonstrated by molecular dynamics simulations, exhibit catch bond behavior where bond lifetimes increase under mechanical load, enabling the design of mechanically adaptive materials with tunable durability and responsiveness.
This paper demonstrates the experimental creation, steering, and parking of individual topological torons in chiral nematic liquid crystals using tailored alternating-current electric fields, enabling deterministic submicrometre control over their trajectories for applications in reconfigurable patterning, micromanipulation, and optical memory.
