Electronic Structures of Fullerenes and Fulleridesshell electronic structure with relatively large energy gap, and solid C. becomes a semiconductor. K. C. is found to be an exotic . and have high density of states at the Fermi energy, which seems responsible for the observed superconductivity. On the other hand, the high electronegativity of C. pre

Structure Optimization and Dynamics of Fine Particles in LCAO Methodsi and Weizsaker terms with modified coefficients. We vary the total energy with respect to the geometric structure and the charge density, which is approximated by the linear combination of atomic charge basis set. Using this procedure we are able to obtain the minimum total energy output of potassi

Traditional and Ab-Initio Molecular Dynamics Simulations — Applications to Glass Transition and Amors. To this end, we first apply the traditional molecular dynamics (MD) techniques to a system composed of classical particles, and study the glass transition as well as the stability of glasses constructed through the glass transition. In the second place, we develop the ab-initio MD program based o

Projection Monte Carlo Method and Choice of the Optimal Trial Wavefunctioneved by propagating in imaginary time a properly chosen trial wavefunction. It is shown that use of a trial wavefunction of definite total spin can enormously improve the convergence in imaginary time in the half filled Hubbard model. Fluctuations of the staggered magnetization become very small in

Recent Progress in the Auxiliary-Field Many-Fermion Simulation Methodtonovich transformation. These are the recently introduced positive-projection approximation, the extension of these methods to lattice models with long-range interactions, and the passage from lattice models to the continuum limit.

Real Space Numerical Renormalization Groups for Hubbard Models-dimensional . systems which makes the renormalization group exact. For the many-particle, interacting case we discuss a technique for producing basis states for a block from wavefunctions on larger systems of which the block is a subset.

Anyons on a Latticeogical structures such as planc(plate), annulus (cylinder) and torus. To realize the system consistently, we start from a braid group analysis. The system is characterized not only by the anyon statistics θ but also by the magnetic fluxes Φ. (and Φ.) threading through the holes of the system. We gen
