PUBLICATIONS


A description of the different research subjects and publications can be found under the Research heading, and slides from presentations I have given and some movies are below. Computer codes associated with each paper are also linked below. I have used the  LyX word processor to create my Ph.D. dissertation, papers and presentations, and highly recommend it to everyone!

Here is a chronological list of my publications along with reprints and recent preprints. I generally recommend using these PDFs instead of journal versions since I update these upon finding small mistakes that do not warrant an official erratum.

MOVIES


Here are some selected animations from my presentations. I often use two dimensions to make it easier to visualize. Newer animations are in the QuickTime format (extension mov). To play MNG animations (file extension mng), I use mngplay under Linux and IrfanView for Windows.
  1. An MP4 movie (QuickTime) illustrating the two-layer structure of driven uniform suspension of microrollers.
  2. An animation produced by Northwestern graduate student Brennan Sprinkle  of an active uniform suspension of microrollers, either 256 spheres with 42 blobs each (gif), or 1024 spheres with 12 blobs each (gif), see Fig. 6 in the paper "Large Scale Brownian Dynamics of Confined Suspensions of Rigid Particles". And here is an animation of an equilibrium suspension of boomerangs sedimented above a bottom wall, see Fig. 2 in the paper.
  3. Supplementary Material Movies for the paper "Brownian Dynamics of Confined Suspensions of Active Microrollers", showing the formation of a nonlocal shock front and a fingering instability in a suspension of microrollers above a bottom wall.
  4. Animation produced by collaborator Changho Kim  showing the propagation of a spherical chemical wave (gif) leaving behind a Turing-like pattern, without thermal fluctuations (left) and with fluctuations (right), see Fig. 8 in  the paper "Stochastic Simulation of Reaction-Diffusion Systems: A Fluctuating-Hydrodynamics Approach", Here is animation of the formation of a Turing pattern in the BPM model with FHD or RDME, as studied in section V.B in the paper
  5. Animation produced by collaborator Andy Nonaka  showing the development of an instability during diffusive mixing of a solution of salt on top of a solution of sugar (QuickTime), comparing the cases when thermal fluctuations are included (and trigger the instability) versus when they are only included initially until the instability is triggered.
  6. Development of giant fluctuations (GIF) during diffusive mixing in two dimensions without bare diffusion (reversible, top) and with bare diffusion (irreversible, bottom).
  7. "Diffusive" evolution of a line of tracers simulated using fluctuating hydrodynamics (animated GIF) without bare-diffusion, and hard-disk molecular dynamics (GIF).
  8. Giant fluctuations observed using the Inertial Incompressible Coupling method (left) and a stochastic advection-diffusion approach (right). A fluctuation-aware version of the immersed boundary code IBAMR was used to produce these animations.
  9. Giant fluctuations during diffusive mixing of two hard-disk fluids, simulated with event-driven molecular dynamics (left) and also with low Mach number fluctuating hydrodynamics. In three dimensions fluctuating hydrodynamics predicts much smaller but still giant fluctuations, as illustrated by the mixing of two hard-sphere fluids.
  10. Giant fluctuations during diffusive mixing of two miscible fluids in two dimensions, with no gravity (top), weak gravity (middle), and strong gravity (bottom). A similar "fractal" interface is seen for a wide range of Schmidt numbers, but there are also visible differences and the rescaling is not perfect.
  11. Rayleigh-Taylor instability (unstable mixing of two ideal gases under gravity) driven entirely by thermal fluctuations, that is, starting with no initial interface perturbation, as calculated using a fluctuating hydrodynamic compressible solver (also as QuickTime, Flash).
  12. Calculation of plug flow past a disk using our particle-continuum hybrid method, which combines a stochastic particle fluid with a fluctuating hydrodynamics continuum (also as QuickTime).
  13. Simulation of the Brownian motion of disk through a fluid using the particle-continuum hybrid code (also as QuickTime, Flash).
  14. Equilibration of an adiabatic piston toward thermal equilibrium, as simulated using the particle-continuum hybrid code (also as QuickTime, Flash).
  15. Brownian motion of a hard-disk polymer chain through a stationary deterministic (hard-sphere) molecular dynamics fluid (also as QuickTime, Flash).
  16. Brownian motion of a hard-disk polymer chain through a sheared stochastic (DSMC) fluid (also as QuickTime, Flash).
Older animations concerning jamming in packings of hard-particles can be found here.
