Self-consistent theory of large amplitude collective motion: Applications to approximate quantization of non-separable systems and to nuclear physics
G. Do Dang, A. Klein, N. R. Walet
The goal of the present account is to review our efforts to obtain and apply a ``collective'' Hamiltonian for a few, approximately decoupled, adiabatic degrees of freedom, starting…
Dynamics of Complex Quantum Systems: Dissipation and Kinetic Equations
Aurel Bulgac, Giu Do Dand, Dimitri Kusnezov
We present a microscopic approach to quantum dissipation and sketch the derivation of the kinetic equation describing the evolution of a simple quantum system in interaction with a…
Exotic Stochastic Processes from Complex Quantum Environments
Dimitri Kusnezov, Aurel Bulgac, Giu Do Dang
Stochastic processes are shown to emerge from the time evolution of complex quantum systems. Using parametric, banded random matrix ensembles to describe a quantum chaotic environm…
Local harmonic approaches with approximate cranking operators
takashi Nakatsukasa, Niels R. Walet, Giu Do Dang
Methods of large amplitude collective motion in the adiabatic limit are examined with a special emphasis on conservation laws. We show that the restriction to point transformations…
A basis of cranking operators for the pairing-plus-quadrupole model
Takashi Nakatsukasa, Niels R. Walet, Giu Do Dang
We investigate the RPA normal-mode coordinates in the pairing-plus-quadrupole model, with an eye on simplifying the application of large amplitude collective motion techniques. At…
Quantum Lévy Processes and Fractional Kinetics
Dimitri Kusnezov, Aurel Bulgac, Giu Do Dang
Exotic stochastic processes are shown to emerge in the quantum evolution of complex systems. Using influence function techniques, we consider the dynamics of a system coupled to a…
