Unstable periodic orbits (UPOs) are believed to be the underlying dynamical structures of spatiotemporal chaos and turbulence. Finding these UPOs is, however, notoriously difficult. Matrix-free loop convergence algorithms deform entire spac...
Universal negative energetic elasticity in polymer chains: Crossovers among random, self-avoiding, and neighbor-avoiding walks [0.03%]

Negative energetic elasticity in gels challenges the conventional understanding of gel elasticity; despite extensive research, a concise explanation remains elusive. In this study, we use the weakly self-avoiding walk (the Domb-Joyce model;...

We examine the scaling of the inverse participation ratio of spin coherent states in the energy basis of three collective spin systems: a bounded harmonic oscillator, the Lipkin-Meshkov-Glick model, and the quantum kicked top. The finite-si...

Thermoacoustic effects arise when a temperature gradient is present in a sound field. This work investigates the interplay of orthogonal sound and thermal fields in a water-filled microchannel. We measured the three-dimensional streaming in...
Quantifying dissipation in flocking dynamics: When tracking internal states matters [0.03%]

Aligning self-propelled particles undergo a nonequilibrium flocking transition from apolar to polar phases as their interactions become stronger. We propose a thermodynamically consistent lattice model, in which the internal state of the pa...

The phenomena of senescence are widely observed during the process of cell mitosis at the cellular level. From the perspective of statistical mechanics, the senescence can be formulated by a random walk process whose dynamic and transitiona...

We demonstrate the densification of a granular model system of 130µm polystyrene spheres over time by shaking with varying excitation amplitudes or effective temperatures. This densification is quantified by the mean-square displacement (M...
Continuum modeling and simulation of a ferroelectric smectic-A liquid crystal [0.03%]

We construct a continuum model of a recently discovered ferroelectric smectic-A (SmA_{F}) liquid crystal that has a layered structure with orientational order and polarization along the layer normal. We take into account the layer order by ...

Collisional Brownian engines have attracted significant attention due to their simplicity, experimental accessibility, and amenability to exact analytical solutions. While previous research has predominantly focused on optimizing mean value...

The analytical expression for shortcuts to adiabaticity for any switching time and any thermally isolated system performing a finite-time and weakly driven process is presented. It is based on the analytical solution of the optimal protocol...
