Topological Aspects of Phase Transitions

In the past decade and a half, an alternative analysis of phase transitions, based in the topological behavior of system configuration spaces, has been introduced. This method offers a new understanding of many phase transitions, particularly those in finite systems, using topology and manifold behavior. While the broadest hypotheses offered by researchers have proven overly optimistic, the met...

Phase Transitions and Critical Phenomena.phase Transitions in Liquid Crystals

The present text is the transcription of an introductory lecture discussing two phase transitions : nematic-isotropic and smectic A-nematic. The emphasis is on simple qualitative features, including Landau ~heories, coherence lengths and scaling properties.

Theory of Magnetic Phase Transitions

The existence of magnetic order (also termed collective magnetism) that is the orderly arrangement of the magnetic spins appearing in materials below an ordering temperature (e.g., the Curie temperature, TC, of a ferromagnet or the Neel temperature, TN, of an antiferromagnet; see Magnetic Moment and Magnetization) points to a class of physical phenomena that can be described as magnetic phase t...

NUMERICAL SIMULATIONS OF THE PHASE TRANSITIONS IN CLUSTERS

We have studied the phase transitions in atomic clusters by molecular dynamics simulation, assuming Lennard-Jones interatomic pair potential. Calculations are performed by DAP parallel computer. The results are analyzed by simulating their orientational distribution plots (dot-plot), and neutron diffraction patterns. It is shown that all the main features of the bulk phase transitions are e...
