Cooling with the aid of high-frequency energy
Zel'dovich Ya.B.
We consider the feasibility in principle of cooling a two-level system (e.g., spins in a magnetic field) by high-frequency energy pumping (a generalization of the known method of dynamic orientation of spins) and the possibility of making use of quasienergy to select the conditions under which the process can be realized.
