Magnetization of matter at extreme conditions broadens the scope for exploratory sciences with laser-produced plasmas. The widespread applications of B-fields include magnetized inertial confinement fusion (ICF), laboratory models of astrophysical phenomenon and characterization of magnetized materials. In this talk, I will share the story of producing ion magnetization in laser-produced plasmas. Conditions for ion magnetization, i.e., ion gyro-radius shorter than the mean free path, or Hall parameter > 1, is particularly challenging to attain in laser-produced plasmas and has not been demonstrated previously. I will show that shock driven implosions with externally imposed magnetic fields can produce such conditions. Furthermore, I will discuss how magnetization can suppress kinetic effects in the hot spot of ICF implosions. This work opens up an experimental platform for the validation of magneto-hydrodynamics models and the study of transport properties in magnetized plasmas. I will also share my journey through the field of high energy density sciences, from the University of Rochester and the University of Michigan, where I worked on ICF and hydrodynamic instabilities.

Bio: Arijit Bose received his Ph.D. in Physics at the University of Rochester in 2017. His thesis work on Inertial Confinement Fusion was supervised by Riccardo Betti. He received the F. J. Horton Graduate Research Fellowship from the Laboratory for Laser Energetics and the Graduate Student Teaching Award in 2012 from the Department of Physics and Astronomy. In 2017, he joined the University of Michigan as a postdoctoral fellow with Dov Shvarts. He is currently a postdoctoral associate in the High Energy Density Physics Division at MIT where he initiated the work on magnetized shock-driven implosions.
