DOI: 10.1016/j.jaerosci.2018.12.009
Abstract: Abstract Tracking the Brownian motion of aerosol particles as they settle in air allows a mass measurement. The particle typically falls downward at its terminal settling velocity; however, the particle occasionally will be displaced upwards… read more here.

Abstract: The nonequilibrium fluctuation relation is a cornerstone of quantum thermodynamics. It is widely believed that the system-bath heat exchange obeys the famous Jarzynski-Wójcik fluctuation theorem. However, this theorem is established in the Born-Markovian approximation under… read more here.
