Representing Physical Phenomena
2018This chapter extends the case study on quantum mechanics to include not only the ‘top-down’ application of group theory to quantum physics but also the ‘bottom-up’ construction of models of the phenomena, with the example of London’s explanation of the superfluid behaviour of liquid helium in terms of Bose–Einstein statistics.

Embodied Simulations of physical phenomena
Proceedings of the 5th International Conference on Movement and Computing, 2018At the crossroads between computational physics, human-computer interaction and mediated performance, the present proposal aims at presenting the vast complexity of physical phenomena in an intuitive, embodied manner. Specifically, we created an interactive system capable of accurately simulating the rules of physical phenomena in game form.

Critical phenomena in atomic physics
Physica E: Low-dimensional Systems and Nanostructures, 2001Abstract It is shown that the threshold energy e =0 for complete break-up of N charged particles represents a fixed point of the dynamical system. Renormalization theory akin to thermodynamical phase transitions is used to determine the exponent β of the power law for the fragmentation cross section σ ( e )∝ e β near the fixed point. In the

Parametric Phenomena in Physics
American Journal of Physics, 1971Parametric excitation of a resonant system is a self-excitation caused by a periodic variation of some parameter of the system. A brief history of parametric phenomena is given from Faraday and Lord Rayleigh through modern day physics. The general characteristics of “parametric generators” are viewed through a specific example from acoustics, which is ...

The paper presents the gallery of physical phenomena found and/or described in the Institute of Thermophysics of Russian Academy of Sciences (Novosibirsk, Russia). The majority of results is related to hydrodynamical or thermophysical processes. The main method of describing processes is their visualisation.

Stochastic phenomena in physics
Acta Applicandae Mathematicae, 1983The basic concepts of stochastic variables and their characterization by stochastic differential equations, diffusion equations and path integrals are reviewed. Applications of stochastic processes are then outlined for problems in optics, spin diffusion, random potentials in solids, and quantum mechanics.
