Guiding-center transformation of the radiation-reaction force in a nonuniform magnetic field
Eero Hirvijoki, Joan Decker, Alain Brizard +1
In this paper, we present the guiding-center transformation of the radiation-reaction force of a classical point charge traveling in a nonuniform magnetic field. The transformation…
Hamiltonian formulation of the gyrokinetic Vlasov-Maxwell equations
J. W. Burby, A. J. Brizard, P. J. Morrison +1
The gyrokinetic Vlasov-Maxwell equations are cast as an infinite-dimensional Hamiltonian system. The gyrokinetic Poisson bracket is remarkably simple and similar to the Morrison-Ma…
Directly imaging damped Ly-alpha galaxies at z>2. III: The star formation rates of neutral gas reservoirs at z~2.7
Michele Fumagalli, John M. O'Meara, J. Xavier Prochaska +2
We present results from a survey designed to probe the star formation properties of 32 damped Ly-alpha systems (DLAs) at z~2.7. By using the "double-DLA" technique that eliminates…
Compact formulas for bounce/transit averaging in axisymmetric tokamak geometry
F. -X. Duthoit, A. J. Brizard, T. S. Hahm
Compact formulas for bounce and transit orbit averaging of the fluctuation-amplitude eikonal factor in axisymmetric tokamak geometry, which is frequently encountered in bounce-gyro…
A note on recognizing an old friend in a new place: list coloring and the zero-temperature Potts model
Joanna A. Ellis-Monaghan, Iain Moffatt
Here we observe that list coloring in graph theory coincides with the zero-temperature antiferromagnetic Potts model with an external field. We give a list coloring polynomial that…
Directly imaging damped Ly-alpha galaxies at z>2. II: Imaging and spectroscopic observations of 32 quasar fields
Michele Fumagalli, John M. O'Meara, J. Xavier Prochaska +2
Damped Ly-alpha absorbers (DLAs) are a well-studied class of absorption line systems, and yet the properties of their host galaxies remain largely unknown. To investigate the origi…
