Dynamo and Jet interconnections in GRMHD simulations of black hole accretion disks
P. S. Santhiya, Pallavi Bhat, Prayush Kumar +2
We present global 3D GRMHD simulations of black hole (BH) accretion disks designed to investigate how MRI-driven dynamo action regulates jet formation and evolution. Unlike standar…

Understanding large-scale dynamos in unstratified rotating shear flows
Tushar Mondal, Pallavi Bhat, Fatima Ebrahimi +1
We combine simulations with new analyses that overcome previous pitfalls to explicate how nonhelical mean-field dynamos grow and saturate in unstratified, magnetorotationally drive…

Quantum Effects on Dynamic Structure Factors in Dense Magnetized Plasmas
Tushar Mondal, Gianluca Gregori
We extend the classical magnetohydrodynamics formalism to include nonlocal quantum behavior via the phenomenological Bohm potential. We then solve the quantum magnetohydrodynamics…
