Resumen
A maximum entropy principle density matrix method, valid for systems with temperature different from zero, is presented making it possible to find two-mode squeezed states in two-level systems with relevant operators and Hamiltonian connected with O(3,2). A method which allows one to relate the appearance of squeezing to the relevant operators, included in order to define the density matrix of the system, is given. 185 4 355 361
