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…
Selective production of metallic carbon nanotubes
Yasushi Matsunaga, Tadatsugu Hatori, Tomokazu Kato
In this report, we discuss whether the optimal electric field to promote the growth of armchair- type nanotubes (metallic character) evaluated using the previous Huckel-Poisson met…
