Waking up with a foggy brain, undecided about whether to dress first or brush your teeth, grabbing your bag, rushing to the car, and arriving at the office wondering what should come first while preparing morning tea. At night, after settling down the kid, scrolling through the phone as a "relaxing" method and trying to be an "informed" citizen, finally falling asleep at an indefinite time. Mornings and evenings were full of decision fatigue.

AbstractParkinson’s disease (PD) is a neurodegenerative disorder with extensive involvement of motor symptoms, imposing a heavy economic burden on patients and society. B lymphocytes, a group of immune cells associated with humoral immunity, have been shown to be involved in the pathogenesis of PD. However, the causal relationship and potential pathogenic effects of B cell in PD remain unclear.

We study the gravitational Bose-Einstein condensation of a massive vector field in the kinetic regime and the nonrelativistic limit using nonlinear dynamical numerical methods. Gravitational condensation leads to the spontaneous formation of solitons. We measure the condensation time and growth rate, and compare to analytical models in analogy to the scalar case. We find that the condensation time of the vector field depends on the correlation between its different components.
