In this note we use Clifford algebras and their Fock representations to build representations of LU(N) and LSU(N). Let H be the Hilbert space of square-integrable sections of the trivial rank N complex vector bundle over S and P : H → H the projection onto the space spanned by non-negative Fourier modes. To this data we can associate the Fermionic Fock space FP . FP is a representation of level...

We present Hartree-Fock surface energies, work functions and dipole barriers for a Jellium slab model at different electron densities and slab widths. The fully self-consistent calculations take into account the nonlocal exchange coupling of the momentum parallel to the surface with the perpendicular component of the orbitals. Typical oszillations due to quantum size effects have been observed....

The role of higher Fock-state contributions to exclusive charmonium decays will be discussed. It will be argued that the J/ψ (ψ) decays into baryon-antibaryon pairs are dominated by the valence Fock-state contributions. P -wave charmonium decays, on the other hand, receive strong contributions from the ccg Fock states since the valence Fock-state contributions are suppressed in these reactions....

ABSTP,CT. A generalized Fock space is introduced as it was developed by Schmeelk [1-5], also Schmeelk and Takai [6-8]. The wavelet transform is then extended to this generalized Fock space. Since each component of a generalized Fock functional is a generalized function, the wavelet transform acts upon the individual entry much the same as was developed by Mikusinski and Mort [9] based upon earl...

The deterministic generation of non-classical states of light, including squeezed states, Fock states and Bell states, plays an important role in quantum information processing and exploration of the physics of quantum entanglement. Preparation of these non-classical states in resonators is non-trivial due to their inherent harmonicity. Here we use stimulated Raman adiabatic passage to generate...

We report on numerical studies of the influence of Coulomb interactions on localization of electronic wavefunctions in a strong magnetic field. Interactions are treated in the Hartree-Fock approximation. Localization properties are studied both by evaluating participation ratios of Hartree-Fock eigenfunc-tions and by studying the boundary-condition dependence of Hartree-Fock eigenvalues. We fin...
