Phase Transitions in Small Systems: Microcanonical vs. Canonical Ensembles
Jörn Dunkel, Stefan Hilbert
We compare phase transition(-like) phenomena in small model systems for both microcanonical and canonical ensembles. The model systems correspond to a few classical (non-quantum) p…

Non-analytic microscopic phase transitions and temperature oscillations in the microcanonical ensemble: An exactly solvable 1d-model for evaporation
Stefan Hilbert, Jörn Dunkel
We calculate exactly both the microcanonical and canonical thermodynamic functions (TDFs) for a one-dimensional model system with piecewise constant Lennard-Jones type pair interac…

Magnetism in (III, Mn)-V Diluted Magnetic Semiconductors: Effective Heisenberg Model
S. Hilbert, W. Nolting
The magnetic properties of the diluted magnetic semiconductors (DMS) (Ga, Mn)As and (Ga, Mn)N are investigated by means of an effective Heisenberg model, whose exchange parameters…
