Alain Brizard, professor of physics, had three peer-reviewed papers published this year: (1) “Perturbative variational formulation of the Vlasov-Maxwell equations” published in Physics of Plasmas; (2) Comment on “Exact solutions and singularities of an x-point collapse in Hall magnetohydrodynamics” published in the Journal of Mathematical Physics; and (3) “Gauge-free electromagnetic gyrokinetic theory” published in Physics Letters A (with J.W. Burby at the Los Alamos National Laboratory). Paper (2) was also the topic of a student-faculty research project (with Colin Myrick, 2020), which was presented by Colin at the 2019 International Sherwood Fusion Theory conference in Princeton in April. Lastly, in May 2019, Brizard gave a seminar “A survey of applications of ray phase-space eikonal methods in linear wave conversion” at the Department of Mathematics of the University of Surrey (UK), where he also was the external examiner for a PhD defense.

Alain Brizard, professor of physics, in recent months has had three papers published in the journal Physics of Plasmas: (1) Centrifugal particle confinement in mirror geometry; (2) Gauge-free electromagnetic gyrokinetic theory; and (3) Perturbative variational formulation of the Vlasov-Maxwell equations. Paper (3) was also presented at the Sherwood Fusion Theory conference in Auburn (Alabama) in April 2018 and Paper (2) will be presented at the 19th International Congress on Plasma Physics in Vancouver (Canada) from June 4-8, 2018. Alain was awarded a three-year grant ($151,750) from the National Science Foundation, which will cover his summer research during the period 2018-2020. This theoretical project, entitled “Nonlinear reduced Hamiltonian and collisional gyrokinetic transport models,” will include collaborations with US and European physicists.

Alain Brizard, professor of physics, was “host” during a rare partial solar eclipse as experienced by nearly 100 Saint Michael’s people around his small telescope set up by the large clock on the main campus green on Aug. 21. Many donned special glasses to view the eclipse. Alain brought out his 40-year-old, personal 3.5-inch Questar telescope and set it up on a table at the site around 1 p.m., shortly after the moon first started to visibly move over the sun, and stayed till the eclipse was over several hours later.

Alain Brizard, professor of physics, during a sabbatical leave in the 2017 spring semester, has taught a short course in gyrokinetic theory at the Institute for Fusion Theory and Simulation at Zhejiang University in Hangzhou (China), April 10-21,the Department of Applied Physics of Aalto University in Espoo (Finland), May 1-18, and the Max Planck Institute for Plasma Physics in Greifswald (Germany), June 12-24. These short courses were or will be taught to graduate students and postdocs as part of his work in writing a graduate-level textbook on gyrokinetic theory (to be published by World Scientific later this year). In the past two years, Alain has published seven peer-reviewed articles with collaborators both in the US and abroad in Physics of Plasmas, the Journal of Plasma Physics, and Communications in Nonlinear Science and Numerical Simulation (with an undergraduate math major at Saint Michael’s). In 2016-2017, he also presented nearly 20 seminars, invited talks, and contributed presentations at national and international conferences.
