Biography

Dr. Arijit Bose is an Assistant Professor in the Department of Physics and Astronomy at the University of Delaware (UD). Prior to UD, he was a Postdoctoral Associate at MIT – Plasma Science and Fusion Center, and a Postdoctoral Fellow at University of Michigan, Ann Arbor. Arijit received his PhD in Physics from the University of Rochester in 2017 and his BSc. (Hons.) in Physics from the Chennai Mathematical Institute, India. He received the F. J. Horton Graduate Research Fellowship to conduct his doctoral thesis research on inertial confinement fusion (ICF) at the Laboratory for Laser Energetics (LLE), which houses the Omega laser facility, a unique national resource for conducting High-Energy-Density Physics experiments.​​

Research

Arijit’s research uses high-power lasers, like the Omega laser at LLE and the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory, or pulsed-power systems, like the Z-machine at Sandia National Laboratory, to study matter at extreme conditions. The experiments replicate various astrophysics phenomena occurring in the universe, scaled down to the laboratory, that are used to unravel intricate physics of the universe. Currently, we are conducting laboratory astrophysics experiments at the Omega laser facility to study strongly magnetized plasma jets and turbulence related to coronal mass ejections from the Sun.

​​The Omega and NIF lasers and the Z pulsed power machine are used to conduct inertial confinement fusion (ICF) experiments. ICF experiments produce conditions like in the center of the sun for nuclear fusion to occur. The volume of the fusion plasma in these high precision ICF experiments is tiny, typically 1/1000 of a millimeter, and sustains fusion for a few hundred picoseconds - one can imagine this to be somewhat like a short-lived miniature star in the laboratory. Our research typically engages collaborations between several research teams at the National Laboratories and Universities. Our group at UD typically conducts numerical simulations to design, analyze and explain various aspects of the ICF experiments.
