Numerical evidence of drift term in two-dimensional point vortex system at negative absolute temperature
Yuichi Yatsuyanagi, Tadatsugu Hatori
The drift term appearing in an anaylitically obtained kinetic equation for a point vortex system is evidenced numerically. It is revealed that the local temperature in a region whe…
Explicit formula of energy-conserving Fokker-Planck type collision term for single species point vortex systems with weak mean flow
Yuichi Yatsuyanagi, Tadatsugu Hatori, Pierre-Henri Chavanis
This paper derives a kinetic equation for a two-dimensional single species point vortex system. We consider a situation (different from the ones considered previously) of weak mean…
Mechanism of self-organization in point vortex system
Yuichi Yatsuyanagi, Tadatsugu Hatori
A mechanism of the self-organization in an unbounded two-dimensional (2D) point vortex system is discussed. A kinetic equation for the system with positive and negative vortices is…
Explicit formula of energy-conserving, Fokker-Planck type collision term for nonaxisymmetric, single species point vortex system
Yuichi Yatsuyanagi, Tadatsugu Hatori
This paper considers a kinetic equation for an unbounded two-dimensional single species point vortex system. No axisymmetric flow is assumed. Using the kinetic theory based on the…
