27 Oct Persistant homology paper in Physica D
Our paper on the use of ideas from persistent homology for large non equilibrium fluid systems has been published in Physica D. This is a large collaborative effort between my group at Virginia Tech, Mike Schatz’ group in the physics department at Georgia Tech, and Konstantin Mischaikow’s group in the match department at Rutgers University. The paper can be found here.
The image above is from a numerical simulation from my group of the spiral defect chaos state of Rayleigh-Benard convection in a large cylindrical domain. Color contours are shown of the temperature of the fluid where red is hot rising fluid and blue is cold falling fluid. The solid black line around the edges indicate the position of the lateral sidewalls of the convection domain.
