Statistical Mechanics and Hydrodynamics of Self-Propelled Hard Spheres
Benjamin Hancock, Aparna Baskaran
Starting from a microscopic model of self-propelled hard spheres we use tools of non-equilibrium statistical mechanics and the kinetic theory of hard spheres to derive a Smoluchows…
Comparison between Smoluchowski and Boltzmann approaches for self-propelled rods
Eric Bertin, Aparna Baskaran, Hugues Chaté +1
Considering systems of self-propelled polar particles with nematic interactions ("rods"), we compare the continuum equations describing the evolution of polar and nematic order par…
Pressure is not a state function for generic active fluids
A. P. Solon, Y. Fily, A. Baskaran +4
Pressure is the mechanical force per unit area that a confined system exerts on its container. In thermal equilibrium, it depends only on bulk properties (density, temperature, etc…
Kinetic Density Functional Theory of Freezing
Arvind Baskaran, Aparna Baskaran, John Lowengrub
A theory of freezing of a dense hard sphere gas is presented. Starting from a revised Enskog theory, hydrodynamic equations that account for non-local variations in the density but…
Nonequilibrium Statistical Mechanics of Self-propelled Hard Rods
Aparna Baskaran, M. Cristina Marchetti
Using tools of nonequilibirum mechanics, we study a model of self-propelled hard rods on a substrate in two dimensions to quantify the interplay of self-propulsion and excluded-vol…
Fluctuations and Pattern Formation in Self-Propelled Particles
Shradha Mishra, Aparna Baskaran, M. Cristina Marchetti
We consider a coarse-grained description of a system of self-propelled particles given by hydrodynamic equations for the density and polarization fields. We find that the ordered m…
Hydrodynamic equations for a granular mixture from kinetic theory - fundamental considerations
James W. Dufty, Aparna Baskaran
In this review, a theoretical description is provided for the solid (granular) phase of the gas-solid flows that are the focus of this book. Emphasis is placed on the fundamental c…
Linear Response and Hydrodynamics for Granular Fluids
James W. Dufty, Aparna Baskaran, J. Javier Brey
A formal derivation of linear hydrodynamics for a granular fluid is given. The linear response to small spatial perturbations of the homogeneous reference state is studied in detai…
Transport Coefficients for the Hard Sphere Granular Fluid
Aparna Baskaran, James W. Dufty, J. Javier Brey
In the preceding paper, linear response methods have been applied to obtain formally exact expressions for the parameters of Navier-Stokes order hydrodynamics. The analysis there i…
Gaussian Kinetic Model for Granular Gases
James W. Dufty, Aparna Baskaran, Lorena Zogaib
A kinetic model for the Boltzmann equation is proposed and explored as a practical means to investigate the properties of a dilute granular gas. It is shown that all spatially homo…
