Semiclassical approaches to nuclear dynamics
Abstract
The extended Gutzwiller trajectory approach is presented for the semiclassical description of nuclear collective dynamics, in line with the main topics of the fruitful activity of V.G. Solovjov. Within the Fermiliquid droplet model, the leptodermous effective surface approximation was applied to calculations of energies, sum rules, and transition densities for the neutron–proton asymmetry of the isovector giantdipole resonance and found to be in good agreement with the experimental data. By using the Strutinsky shell correction method, the semiclassical collective transport coefficients, such as nuclear inertia, friction, stiffness, and moments of inertia, can be derived beyond the quantum perturbation approximation of the response function theory and the cranking model. The averaged particlenumber dependences of the lowlying collective vibrational states are described in good agreement with the basic experimental data, mainly due to the enhancement of the collective inertia as compared to its irrotational flow value. Shell components of the moment of inertia are derived in terms of the periodicorbit freeenergy shell corrections. A good agreement between the semiclassical extended Thomas–Fermi moments of inertia with shell corrections and the quantum results is obtained for different nuclear deformations and particle numbers. Shell effects are shown to be exponentially dampted out with increasing temperaturemore »

Starting with the semiclassical initial value representation (IVR) for the description of a composite molecular system consisting of a {open_quotes}system{close_quote}{close_quote} and a {open_quotes}bath,{close_quote}{close_quote} we show a systematic procedure whereby one can retain the semiclassical IVR description of the {open_quotes}system{close_quote}{close_quote}{emdash}thus including quantum interference and tunneling effects for these degrees of freedom{emdash}while neglecting these effects in the {open_quotes}bath{close_quote}{close_quote} degrees of freedom, thus reducing them to a classical description. The zeroth order version of this mixed semiclassical{endash}classical model is seen to be the semiclassical equivalent of the Ehrenfest model (closely related to the TDSCF approximation), but higher order versions are also developed thatmore »

Comparison of quantummechanical and semiclassical approaches for an analysis of spin dynamics in quantum dots
Two approaches to the description of spin dynamics of electronnuclear system in quantum dots are compared: the quantummechanical one is based on direct diagonalization of the model Hamiltonian and semiclassical one is based on coupled equations for precession of mean electron spin and mean spin of nuclear spin fluctuations. The comparison was done for a model problem describing periodic excitation of electronnuclear system by optical excitation. The computation results show that scattering of parameters related to fluctuation of the nuclear spin system leads to appearance of an ordered state in the system caused by periodic excitation and to the effectmore » 
Semiclassical inertia of nuclear collective dynamics
For the lowlying collective excitations in nuclei, the transport coefficients, such as the stiffness, the inertia, and the friction, are derived within the periodicorbit theory in the lowest orders of semiclassical expansion corresponding to the extended ThomasFermi approach. The multipole vibrations near the spherical shape are described in the meanfield approximation through the infinitely deep squarewell potential and Strutinsky averaging of the transport coefficients. Owing to the consistency condition, the collective inertia for sufficiently increased particle numbers and temperatures is substantially larger than that of irrotational flow. The average energies of collective vibrations, reduced friction, and effective damping coefficients aremore » 
Charge transfer between S{sup 2+} and He: A comparative study of quantal and semiclassical approaches
A comparative study of charge transfer in collisions of groundstate S{sup 2+} ions with He has been performed within fully quantal and semiclassical molecularorbit closecoupling approaches. The processes for capture into S{sup +}({sup 4}S{sup 0},{sup 2}D{sup 0},{sup 2}P{sup 0})+He{sup +} are taken into account. Quantal and semiclassical cross sections were evaluated, respectively, in the diabatic and adiabatic representations and found to be in good agreement. The calculations show that at collision energies below about 40 eV/u, the chargetransfer processes are dominated by S{sup 2+}({sup 3}P)+He{yields}S{sup +}({sup 2}D{sup 0})+He{sup +}, and capture into the {sup 2}P{sup 0} and {sup 4}S{sup 0}more » 
Semiclassical approaches to belowthreshold harmonics
We study the generation of belowthreshold harmonics in a model atom by extending the threestep semiclassical model of harmonic generation to include effects of the atomic potential. We explore the generalization of semiclassical trajectories of the electron in the presence of the combined laseratom potential and calculate the intensitydependent dipole phase associated with these trajectories. Our results are in good agreement with fully quantum mechanical calculations, as well as with recent experimental observations. We show that the socalled long trajectory readily generalizes to belowthreshold harmonic generation and is relatively insensitive to the choice of initial conditions. We also find thatmore »
