1.
Distributed Information Services in Physics / Hilf, E ; Hohlfeld, M ; Severiens, T ; Zimmermann, K
The concept of distributed information services maintained by a distributed work force for scientific information is described. Realizations and experiences for Physics (since 1995), Marine Sciences, and dissertation theses in physics are presented. [...]

Specific heat in the thermodynamics of clusters / Borrmann, P ; Gloski, D ; Hilf, E R
The thermodynamic properties such as the specific heat are uniquely determined by the second moments of the energy distribution for a given ensemble averaging. [...]

Paradoxical Magnetic Cooling in a Structural Transition Model / Borrmann, P ; Stamerjohanns, H ; Hilf, E R ; Tománek, D
In contrast to the experimentally widely used isentropic demagnetization process for cooling to ultra-low temperatures we examine a particular classical model system that does not cool, but rather heats up with isentropic demagnetization. This system consists of several magnetite particles in a colloidal suspension, and shows the uncommon behavior of disordering structurally while ordering magnetically in an increasing magnetic field. [...]

Calculation of thermodynamic properties of finite Bose-Einstein systems / Borrmann, P ; Harting, J ; Mülken, O ; Hilf, E R
We derive an exact recursion formula for the calculation of thermodynamic functions of finite systems obeying Bose-Einstein statistics. The formula is applicable for canonical systems where the particles can be treated as noninteracting in some approximation, e.g. [...]

Thermodynamics of finite magnetic two-level systems / Borrmann, P ; Stamerjohanns, H ; Hilf, E R ; Jund, P ; Kim, S G ; Tománek, D
We use Monte Carlo simulations to investigate the thermodynamical behaviour of aggregates consisting of few superparamagnetic particles in a colloidal suspension. [...]

Simple quantum mechanical phenomena and the Feynman real time path integral / Dullweber, A ; Hilf, E R ; Mendel, E
The path integral formalism gives a very illustrative and intuitive understanding of quantum mechanics but due to its difficult sum over phases one usually prefers Schr\"odinger's approach. [...]

Structures and stabilities of H3+(H2)n clusters (n=1-11) / Diekmann, B ; Borrmann, P ; Hilf, E R
Geometries and energies for H3+(H2)n clusters (n = 0, ..., 11) have been calculated using standard "ab initio" methods. [...]

Magnetism of small transition metal clusters and the effects of isomerisation / Borrmann, P ; Diekmann, B ; Hilf, E R ; Tománek, D
We investigate the magnetic properties of small transition metal clusters using a simple statistical model, which requires some input data from ab initio spin-density functional calculations. [...]

New enhancements to Feynman's path integral for fermions / Borrmann, P ; Hilf, E R
We show that the computational effort for the numerical solution of fermionic quantum systems, occurring e.g., in quantum chemistry, solid state physics, field theory in principle grows with less than the square of the particle number for problems stated in one space dimension and with less than the cube of the particle number for problems stated in three space dimensions.
