Abstract: | We consider a system described by a Fokker-Planck equation
with a new type of momentum-dependent drift coefficient
which asymptotically decreases as -1/p for a large momentum p.
It is shown that the steady-state of this system
is a κ-generalized Gaussian distribution, which
is a non-Gaussian distribution with a power-law tail. |
