Quantum canonical ensemble: a projection operator approach
Wim Magnus, Fons Brosens
Fixing the number of particles , the quantum canonical ensemble imposes a constraint on the occupation numbers of single-particle states. The constraint particularly hampers the…
Probability assignment in a quantum statistical model
L. F. Lemmens, Burhan Bakar
The evolution of a quantum system, appropriate to describe nano-magnets, can be mapped on a Markov process, continuous in . The mapping implies a probability assignment that can…
Blocking temperature in magnetic nano-clusters
Burhan Bakar, L. F. Lemmens
A recent study of nonextensive phase transitions in nuclei and nuclear clusters needs a probability model compatible with the appropriate Hamiltonian. For magnetic molecules a repr…
Use of the chemical potential for a limited number of fermions with a degenerate groundstate
L. F. Lemmens, F. Brosens, J. T. Devreese
For fermions with degenerate single-particle energy levels, the usual relation between the total number of particles and the chemical potential is only satisfied for a specific…
Density of a gas of spin polarized fermions in a magnetic field
S. Foulon, F. Brosens, J. T. Devreese +1
For a fermion gas with equally spaced energy levels that is subjected to a magnetic field, the particle density is calculated. The derivation is based on the path integral approach…
Addendum on rotational properties of confined bosons: time-inversion referencing
F. Brosens, J. T. Devreese, L. F. Lemmens
In this addendum we introduce the concept of time-inversion referencing. This is an extension of hypertext allowing authors to cite papers that where not yet published (or even not…
