Electromagnetic Observables of Weakly Collisional Black Hole Accretion
Vedant Dhruv, Ben Prather, Mani Chandra +2
The black holes in the Event Horizon Telescope sources Messier 87* and Sagittarius A* (SgrA*) are embedded in a hot, collisionless plasma that is fully described in kinetic theory…

Spatio-temporal spin transport from first principles
Mayada Fadel, Joshua Quinton, Mani Chandra +3
We introduce a computational framework for first-principles density matrix transport within the Wigner function formalism to predict transport of quantum-mechanical degrees of free…

Magnetic-field dependence of spin-phonon relaxation and dephasing due to g-factor fluctuations from first principles
Joshua Quinton, Mayada Fadel, Junqing Xu +4
The electron spin decay lifetime in materials can be characterized by relaxation (T1) and irreversible (T2) and reversible (T2*) decoherence processes. Their interplay leads to a c…
