Deceptive signals of phase transitions in small magnetic clusters
Heinrich Stamerjohanns, Oliver Muelken, Peter Borrmann
We present an analysis of the thermodynamic properties of small transition metal clusters and show how the commonly used indicators of phase transitions like peaks in the specific…
The Origins of Phase Transitions in Small Systems
Oliver Muelken, Heinrich Stamerjohanns, Peter Borrmann
The identification and classification of phases in small systems, e.g. nuclei, social and financial networks, clusters, and biological systems, where the traditional definitions of…
Classification of phase transitions of finite Bose-Einstein condensates in power law traps by Fisher zeros
Oliver Muelken, Peter Borrmann, Jens Harting +1
We present a detailed description of a classification scheme for phase transitions in finite systems based on the distribution of Fisher zeros of the canonical partition function i…
Thermodynamics of finite magnetic two-level systems
Peter Borrmann, Heinrich Stamerjohanns, Eberhard Hilf +3
We use Monte Carlo simulations to investigate the thermodynamical behaviour of aggregates consisting of few superparamagnetic particles in a colloidal suspension. The potential ene…
