This study utilizes molecular dynamics simulations to investigate the flow dynamics of two-dimensional deformable ring particles in a confined channel, revealing how particle stiffness influences flow properties and leads to the effective segregation of soft and hard particles in mixtures.
This study investigates the formation, motion, and interactions of topological defects in both the translational lattice and the geometrically frustrated spin states of vertically confined buckled colloidal monolayers, revealing how these defects drive grain boundary structures and spin domain coarsening to predict the system's material properties and aging.
Through experiments on a colloidal particle in an optical tweezer, the authors demonstrate that simultaneously scaling deterministic forces and adding external noise accelerates the Langevin clock, thereby keeping driven systems closer to thermal equilibrium and enabling more precise free-energy recovery for applications in thermodynamic computing.
This paper employs the random first-order transition theory and a generalized Master equation to characterize the non-Markovian, aging dynamics of thermal avalanches in driven amorphous systems, utilizing full counting statistics to derive the complete distributions of avalanche magnitudes and counts under various driving protocols.
This paper proposes a nonequilibrium generalization of the GENERIC formalism for relaxation to steady states, characterizing macroscopic evolution as a zero-cost flow derived from an extended Onsager-Machlup action where the time-symmetric frenesy component, identified via local detailed balance and canonical decomposition, fundamentally shapes the dynamics.
This study reveals that the Integration Host Factor (IHF) switches from a DNA-bending function at physiological pH to a DNA-bridging mechanism under acidic biofilm-like conditions (pH < 5) due to protonation-induced exposure of positively charged residues, thereby explaining its structural role in biofilm stability.
This paper develops a nonlinear poroelastic theory to predict large and fast diffusiophoretic deformations in hydrogels driven by external or internally generated solute gradients, demonstrating that tuning stimulus concentration, solute particle size, and flow can significantly enhance strain rates for potential applications in soft robotics and drug delivery.
This paper presents a method to fabricate tunable, centimetric elastic capsules that function as macroscopic "elasto-drops" with adjustable effective surface tension, demonstrating that their dynamics are governed primarily by hoop stress rather than bending stiffness.
This paper demonstrates through numerical simulations that a self-propelled two-dimensional elastic sheet exhibits hallmark features of turbulent dynamics, such as power-law energy scaling and non-Gaussian velocity statistics, thereby extending the concept of active turbulence to solid-state active matter like bacterial colonies and epithelial cell layers.
This study reveals that defect creation and annihilation in diverse active living systems exhibit spatial symmetry breaking and irreversibility driven by a dualism between nematic structure and polar forces, challenging conventional active nematic theories and highlighting these processes as major sources of entropy production.
This paper presents a thermodynamically consistent coarse-graining framework based on Doi-Peliti field theory that maps interacting particles to exact field theories, revealing how Poissonian statistics and noise effects govern distinct phase transition behaviors in low- and high-density regimes of the active Ising model.
This paper compares three frameworks for modeling complex fluid flows—local conservation laws, the GENERIC formalism, and the Onsager principle—by illustrating their application to isothermal and incompressible polymeric fluids.
This paper investigates a generalized two-species Vicsek model with reciprocal intra- and interspecies alignment couplings, revealing that anti-aligning interactions can surprisingly promote global polar order and novel microphase separation, a mechanism that extends to multi-species systems with cyclic interactions.
This paper analytically and numerically investigates a lattice Lorentz gas on a cylinder, demonstrating how crowding and quasi-confinement induce a dimensional crossover from two to one dimensions in equilibrium and characterizing the resulting stationary velocity and diffusion under an external pulling force to first order in obstacle density.
This paper theoretically and numerically investigates light propagation in hyperuniform disordered photonic crystal slabs, revealing that intrinsic radiative loss (non-Hermiticity) fundamentally alters disorder scattering from a power-law dependence to a form dominated by a finite constant plus a modified power-law term, a finding validated through simulations with realistic parameters.
This paper presents an analytical model based on elastica theory with contact friction to predict the three distinct sliding modes (Folding, Pinning, and Unfolding) of a naturally curved cylindrical shell entering a rigid hole, offering a validated framework that replaces empirical snap-fit design with a predictive understanding of the interplay between elasticity, geometry, and friction.
