We will show howthe internal atomic dynamics can be deeply affected by the non equilibrium configurationleading to unexpected phenomena like a spontaneous inversion of population, new coolingmechanisms obtained by heating the system [1], and the possibility to create and protect entanglementin a stationary and robust way [2]. Finally, we will discuss how this system maydirectly allow the realization of atomic quantum thermal machines, with high efficiency and agenuine quantum behavior [3].------------[1] B. Bellomo, R.
