Abstract: THE TIME DEPENDENT HARTREE-FOCK-BOGOLIUBOV EQATIONS OF MOTION PROVED ITS
HABILITY TO EVALUATE THE DISSIPATION OF MANY BODY QUANTUM SYSTEMS DURING
THE TUNNELING OF A POTENTIAL BARRIER. SUCH APPROACHES ARE INVESTIGATED
WITH THE AIM TO UNDERSTAND BETTER THE DAMPING PHENOMENA AND THEIR INFLUENCE
ON DISINTEGRATION PROCESSES IN A WIDE RANGE OF MASS ASYMMETRIES, INCLUDING
ALPHA DECAY, CLUSTER EMISSION AND FISSION. A GENERALIZED FORM OF THE TIME
DEPENDENT HARTREE-FOCK-BOGOLIUBOV EQUATIONS WILL BE USED ABLE TO DESCRIBE
THE FLOW OF ENERGY FROM COLLECTIVE DEGREES OF FREEDOM IN INTRINSIC ONE
FOR SENIORITY ONE MANY BODY SYSTEMS. THIS EQUATIONS TAKE INTO ACCOUNT
RESIDUAL INTERACTIONS AS THE PAIRING OR AS THE RADIAL COUPLING THAT CAUSE THE
LANDAU-ZENER EFFECT. THESE EQUATIONS ARE ABLE TO PREDICT A NON ZERO PROBABILITY
THAT A SYSTEM ARRIVE IN THE GROUND STATE AFTER THE SCISSION CONFIGURATION,
SUCH BEHAVIOR BEING AVOIDED WITHIN THE CLASSICAL TIME DEPENDENT HARTREE-FOCK
EQUATIONS OF MOTION FOR MANY BODY SYSTEMS. IT IS INTENDED TO GENERALIZE THESE
EQUATIONS IN ORDER TO DESCRIBE THE BOGOLIUBOV PAIR RUPTURE DURING THE MOTION
OF THE SYSTEM. THE TRAJECTORIES IN THE CONFIGURATION SPACE ARE ALWAYS
DETERMINED DYNAMICALLY USING THE LAST ACTION PRINCIPLE.
