DESCRIPTION:In this talk\, we address the building of finite-time adiabati
 c processes at the mesoscale\, i.e. processes in which the average heat ex
 change between the system and its surroundings vanishes. Specifically\, we
  consider a  Brownian particle trapped by a harmonic potential and immerse
 d in a fluid. Therein\, we analyse some general properties and\, in partic
 ular\, we show that there emerges a minimum time for connecting two equili
 brium states with such a finite-time adiabatic process. Also\, we look int
 o a different optimisation problem\, namely that of the final temperature 
 for a given connection time. Interestingly\, we find out that this second 
 problem is closely related to the first one: both of them are controlled b
 y the same function. Finally\, we discuss some perspectives for future wor
 k.<br> <br> (In collaboration with Carlos A. Plata\, David Gu&eacute\;ry-O
 delin and Emmanuel Trizac)
