Multicritical behaviour of the compressible systems
, 2005 The behaviour of uniform elastically isotropic compressible systems in critical and tricritical points is described in field-theoretical terms. Renormalizationgroup equations are analyzed for the case of three-dimensional systems in a two-loop approximation.

Multicriticality in Hexatic Liquid Crystals
Physical Review Letters, 1986The elegant theories of defect mediated transitions1 provide an interesting scenario for melting of two dimensional crystals. In particular they predict an intermediate phase with quasi-long-range orientational order: the hexatic 2. However, observation of the crystal-hexatic-liquid sequence in either experiments or simulations has proved ...

Multicritical phenomena at surfaces
Surface Science, 1976Abstract Phase transitions at the surface of magnetic systems and binary alloys and in adsorbed surface layers are studied in terms of both phenomenological theories and the statistical mechanics of simple models. In both magnetic materials and alloys new types of multicritical phenomena occur if the atomic interactions in the surface layer differ ...

Multicritical behaviour at surfaces
Zeitschrift f�r Physik B Condensed Matter, 1983The critical behaviour of a semi-infiniten-vector model with a surface term (c/2) ∫dSφ2 is studied in 4-e dimensions near the special transition. It is shown that all critical surface exponents derive from bulk exponents and η∥, the anomalous dimension of the order parameter at the surface.

Experiments on multicritical points
Ferroelectrics, 1984Abstract Crystals undergoing structural phase transitions show, under application of uniaxial stress, a rich variety of multicritical points due to symmetry breaking. Most of the results were obtained in crystals with perovskite structure which are cubic at high temperatures.

Multicritical behavior in LaAlO3
Solid State Communications, 1984Abstract The bicritical and tetracritical phase diagrams of LaAlO 3 under [111] and [100] stresses, respectively are studied by a perturbational calculation around the mean field solution. Our results have essential consequences concerning the theoretical interpretation of recent experiments by Muller et al.
