On the asymptotic distinct prime partitions of integers
M. V. N. Murthy, M. Brack, R. K. Bhaduri
We discuss , the number of ways a given integer may be written as a sum of distinct primes, and study its asymptotic form valid in the limit . We…
Fragmentation of the photoabsorption strength in neutral and charged metal microclusters
C. Yannouleas, R. A. Broglia, M. Brack +1
The line shape of the plasma resonance in both neutral and charged small sodium clusters is calculated. The overall properties of the multipeak structure observed in the photoabsor…
Coupling of Surface and Volume Dipole Oscillations in C-60 Molecules
M. Brack, P. Winkler, M. V. N. Murthy
We first give a short review of the ``local-current approximation'' (LCA), derived from a general variation principle, which serves as a semiclassical description of strongly colle…
Occurrence of periodic Lamé functions at bifurcations in chaotic Hamiltonian systems
M. Brack, M. Mehta, K. Tanaka
We investigate cascades of isochronous pitchfork bifurcations of straight-line librating orbits in some two-dimensional Hamiltonian systems with mixed phase space. We show that the…
Quantum fluid-dynamics from density functional theory
S. Kümmel, M. Brack
A partial differential eigenvalue equation for the density displacement fields associated with electronic excitations is derived in the framework of density functional theory. Our…
Simple Analytical Particle and Kinetic Energy Densities for a Dilute Fermionic Gas in a d-Dimensional Harmonic Trap
Matthias Brack, Brandon P. van Zyl
We derive simple analytical expressions for the particle density and the kinetic energy density for a system of noninteracting fermions in a dimensional isotropic…
