In his seminal work on stochastic particle transport in periodic potentials [1] , claims that the overall energy, in underdamped conditions, plays the role of a slow dynamic variable, compared to position and velocity. The scope of this communication is to show that this claim is incorrect and...
However, particle inertia and gravitational drift significantly influence particle diffusivity. The dependencies also occur for particle velocity fluctuations as shown in the following. Similar to the definition of fluid turbulent kinetic energy, the turbulent kinetic energy of the particles can be defined...
The particles in a system are always in what kind of motion? Constant and random Static Slow and random Fast and follow a curved path 2 . As a substance changes state from a liquid to a gas, the amount of energy the particles have … ...
The motion of cold plasmaspheric ions entering the reconnection region differs from that of warmer magnetosheath and magnetospheric ions. In contrast to the warmer ions, which are probably accelerated by reconnection in the diffusion region near the subsolar magnetopause, the colder ions are simply ...
At that moment, the particles jump to contact and fuse into a single crystal9. Analysis of the particle motion showed that Coulomb forces alone could account for the jump to contact with an effective difference of only one net unit charge on the surface of the particles, but a detailed ...
The velocity vector is used to modify the motion path of the swarm; the position vector represents a potential solution for the optimization problem. Here, j=1,2,…,D, D represents the dimension of the constraint space. The equations for updating the velocity and position of the particle ...

Momentum and energy are conserved by the creation of two new particles. In the case of a charged elementary particle (for example an electron), two photons are created which travel off in opposite directions. 1.1.2 Symmetries Besides particle content, the SM can be characterized in terms of ...
摘要: By virtue of the "invariant eigen-operator" method which originates from the Heisenberg equation of motion, we derive energy-level gap of some dynamic Hamiltonians in many particle physics, which includes a Tomonaga model and spin wave model.关键词:...
