Classification of phase transitions in small systems
We present a classification scheme for phase transitions in finite systems like atomic and molecular clusters based on the Lee-Yang zeros in the complex temperature plane. In the limit of infinite particle numbers the scheme reduces to the Ehrenfest definition of phase transitions and gives the right critical indices. We apply this classification scheme to Bose-Einstein condensates in a harmoni...
متن کاملPhase Transitions in Small Systems: Microcanonical vs. Canonical Ensembles
We compare phase transition(-like) phenomena in small model systems for both microcanonical and canonical ensembles. Our model systems correspond to a few classical (non-quantum) point particles confined in a one-dimensional box and interacting via Lennard-Jones-type pair potentials. Already by means of these simple examples it can be shown that microcanonical thermodynamic functions of a small...
متن کاملThe Origins of Phase Transitions in Small Systems
(Dated: February 1, 2008) 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 phase transitions are not applicable, is important to obtain a deeper understanding of the phenomena observed in such systems. Within a simple statistical model we investigate the validity a...

متن کاملPhase Transitions in " Small " Systems – a Challenge for Thermodynamics – *
Traditionally, phase transitions are defined in the thermodynamic limit only. We propose a new formulation of equilibrium thermo-dynamics that is based entirely on mechanics and reflects just the geometry and topology of the N-body phase-space as function of the conserved quantities, energy, particle number and others. This allows to define thermo-statistics without the use of the thermodynamic...
