Pair correlation of dilute active Brownian particles: From low-activity dipolar correction to high-activity algebraic depletion wings
نویسندگان
چکیده
We study the pair correlation of active Brownian particles at low density using numerical simulations and analytical calculations. observe a winged correlation: While accumulate in front an particle as expected, depletion wake consists two wings. In limit soft particles, we obtain closed equation for correlation, allowing us to characterize particular, unveil regimes high activity, where wings adopt self-similar profile decay algebraically. also perform experiments self-propelled Janus indeed

Ideal bulk pressure of active Brownian particles.
The extent to which active matter might be described by effective equilibrium concepts like temperature and pressure is currently being discussed intensely. Here, we study the simplest model, an ideal gas of noninteracting active Brownian particles. While the mechanical pressure exerted onto confining walls has been linked to correlations between particles' positions and their orientations, we ...
متن کاملNonlinear Dynamics of Active Brownian Particles
We consider finite systems of interacting Brownian particles including active friction in the framework of nonlinear dynamics and statistical/stochastic theory. First we study the statistical properties for 1−d systems of masses connected by Toda springs which are imbedded into a heat bath. Including negative friction we find N + 1 attractors of motion including an attractor describing dissipat...

comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...

Proof One follows the argument in [1, pp. 432 – 433] (cf. also [2, Sec. 9]) to show that for each fixed badly approximable (k − 2)-tuple (α1, . . . , αk−2) there is a set of second Baire category of (αk−1, αk) ∈ T2 such that conditions (i), (ii), and (iii) of Theorem 1.7 hold for α = (α1, . . . , αk). Because the set of badly approximable (k − 2)-tuples is dense in Tk−2, and the set of second B...
