Hamiltonian dynamics of a particle interacting with a wave field
Daniel Egli, Jürg Fröhlich, Zhou Gang +2
We study the Hamiltonian equations of motion of a heavy tracer particle interacting with a dense weakly interacting Bose-Einstein condensate in the classical (mean-field) limit. So…
On the theory of slowing down gracefully
Juerg Froehlich, Zhou Gang
We discuss the transport of a tracer particle through the Bose Einstein condensate of a Bose gas. The particle interacts with the atoms in the Bose gas through two-body interaction…
On Blowup in Nonlinear Heat Equations
D. Egli, Z. Gang, W. Kong +1
We establish the asymptotics of blowup for nonlinear heat equations with superlinear power nonlinearities in arbitrary dimensions and we estimate the remainders.
Friction in a Model of Hamiltonian Dynamics
Juerg Froehlich, Zhou Gang, Avy Soffer
We study the motion of a heavy tracer particle weakly coupled to a dense ideal Bose gas exhibiting Bose-Einstein condensation. In the so-called mean-field limit, the dynamics of th…
Some Hamiltonian Models of Friction II
Daniel Egli, Gang Zhou
In the present paper we consider the motion of a very heavy tracer particle in a medium of a very dense, non-interacting Bose gas. We prove that, in a certain mean-field limit, the…
Some Hamiltonian Models of Friction
Juerg Froehlich, Zhou Gang, Avy Soffer
Mathematical results on some models describing the motion of a tracer particle through a Bose-Einstein condensate are described. In the limit of a very dense, very weakly interacti…
