More precisely\, given the ini tial population of the system in the energy eigenbasis\, I will state the necessary and sufficient conditions for the existence of a Markovian therm al process that transforms the system into a state with a given final popu lation. This will provide an exhaustive H-type theorem in terms of a conti nuous family of entropic functions that need to monotonically increase dur ing the dynamics.\n\nI will also present an algorithm that in a finite num ber of steps allows one to construct the full cone of population vectors a chievable from a given initial state. Moreover\, I will demonstrate that a ll such vectors can be obtained from the initial state by a universal set of elementary thermal controls given by two-level partial thermalisations. Finally\, I will employ these results to investigate optimal work extract ion and cooling processes\, illustrating the role that memory effects play in thermodynamic protocols.\n\nTo request the zoom link\, please send a m essage cqsiadmin@uts.edu.au using your business/organisation/institution e mail address.\n LOCATION:https://researchseminars.org/talk/UTSQSI/34/ END:VEVENT END:VCALENDAR
