We describe a practical method for constructing axisymmetric two-integral galaxy models (with distribution functions of the form f (E, L z), in which E is the or-bital energy, and L z is the vertical component of the angular momentum), based on Schwarzschild's orbit superposition method. Other f (E, L z)-methods are mostly based on solving the Jeans equations or on finding the distribution func...

We describe an approach to optical non-reciprocity that exploits the local helicity of evanescent electric fields in axisymmetric resonators. By interfacing an optical cavity to helicity-sensitive transitions, such as Zeeman levels in a quantum dot, light transmission through a waveguide becomes direction-dependent when the state degeneracy is lifted. Using a linearized quantum master equation,...

A pair of two dimensional fast cameras with a wide angle view (allowing a full radial and toroidal coverage of the lower divertor) was installed in the National Spherical Torus Experiment in order to monitor non-axisymmetric effects. A custom polar remapping procedure and an absolute photometric calibration enabled the easier visualization and quantitative analysis of non-axisymmetric plasma ma...

Numerical studies have been made of the mean thermal structure and of heat transfer by the axisymmetric regime of thermal convection in an annulus of liquid that rotates at .. rad/sec about a vertical axis and is subject to a horizontal temperature contrast dT C*. The non-linear time-dependent equations for axisymmetric flow have been integrated numerically on an I.B.M. 7094 computer for values...

We describe a general radiative equilibrium and temperature correction procedure for use in Monte Carlo radiation transfer codes with sources of temperature-independent opacity, such as astrophysical dust. The technique utilizes the fact that Monte Carlo simulations track individual photon packets, so we may easily determine where their energy is absorbed. When a packet is absorbed, it heats a ...

Using an analogy with an Ising-like spin model, we define microcanonical measures for the dynamics of three dimensional (3D) axisymmetric turbulent flow in a Taylor-Couette geometry. We compute the relevant physical quantities and argue that axisymmetry induces a large scale organization in turbulent flows. We show that there exists a low energy, low temperature regime, for which the orthoradia...

A plasma that is confined in a closed field line geometry such as a levitated dipole may be subject to the formation of convective cells. Using a “Drift” fluid model we show that such flow patterns can represent an appropriate equilibrium in a dipole field that contains a plasma with a non-axisymmetric pressure profile. This can provide a means of fueling and heating a dipole confinement device...
