This article studies the particle temperature distribution depending on the laser radiation power and the particle’s trajectory and velocity. The uneven heating of particles moving in the laser radiation field is identified. The regimes of laser heating without melting, with partial melting, and with complete particle melting are considered.

the purpose of this paper is to investigate the egm method and the behavior of a solid particle suspended in a twodimensional rectangular cavity due to conjugate natural convection. a thermal lattice boltzmann bgk model is implemented to simulate the two dimensional natural convection and the particle phase was modeled using the lagrangian–lagrangian approach where the solid particles are treat...

We study an analogue of the quantum Zeno paradox for the Bohm trajectory of a sharply located particle. We show that a continuously observed Bohm trajectory is the classical trajectory. Our results are then compared and contrasted with Mott’s original treatment of an α-particle track produced by a decaying nucleus in a cloud chamber using standard quantum mechanics.

We provide a method to determine the motion of a classical massive particle in a background geometry of 2-dimensional gravity theories, for which the Birkhoff theorem holds. In particular, we get the particle trajectory in a continuous class of 2-dimensional dilaton gravity theories that includes the Callan-Giddings-HarveyStrominger (CGHS) model, the Jackiw-Teitelboim (JT) model, and the d-dime...

Consider any stationary Schroedinger wave equation (SWE) solution ψ(x) for a particle. The corresponding PDF on position x of the particle is pX(x) = |ψ(x)| . There is a classical trajectory x(t) for the particle that is consistent with this PDF. The trajectory is unique to within an additive constant corresponding to an initial condition x(0). However the value of x(0) cannot be known. As an e...

Tracking the “real” trajectory of a quantum particle is one of the interpretation problem and it is expressed by the Brownian (stochastic) motion suggested by E. Nelson. Especially the dynamics of a radiating electron, namely, “radiation reaction” which requires us to track its trajectory becomes important in the high-intensity field physics by PW-class lasers at present. It has been normally t...
