The theory of changing symmetry within a phase transition was initially described by L.D. Landau. This chapter describes second﹐rder phase transitions by Landau's phenomenological theory. At second﹐rder phase transitions the symmetry of the system is decreased and the emerging phase is ...
Spontaneous Symmetry Breaking and Landau Phase Transition in Horava GravityHigh Energy Physics - TheoryGeneral Relativity and Quantum CosmologyPresence of higher derivative terms in the Horava model of gravity can generate an instability in the Minkowski ground state. This in turn leads to a space ...
LANDAU DESCRIPTION OF THE SUPERCONDUCTING PHASE TRANSITIONPROBECIRCUITDOUBLE-RESONANCEFocusing on an order parameter that signals the breakdown of a global symmetry, we employ a dual formulation of the Ginzburg-Landau model to obtain a Landau description of the phase transition of three-dimensional type...

The first phase transition, although a $Z_2$ symmetrybreaking transition, contains critical exponents that are different from thoseobtained from the Ginzburg-Landau theory of Ising universality class. Thesecond transition does not even involve a change of symmetry and has nosymmetry breaking order ...
The mechanism of B_2→R and R→M phase transition in near stoichiometric NiTi alloy has been studied. B_2→R transition is due to the formation of CDW′s. R→M transition has the shear mechanism, caused by soft "1/2" type TA phonon coupled with the strain. The symmetry of R phase...

This phase transition is characterized by the appearance of a spontaneous polarization, which is the result of a symmetry-breaking process. Landau-Devonshire theory has been successful in describing a wide range of phenomena in ferroelectric materials, including phase transitions, domain wall formation,...

Transitions between M=-S and (S-n), with n even or odd, revealed a parity (symmetry) effect which is analogous to the suppression of tunneling predicted for half integer spins. This observation is the first direct evidence of the topological part of the quantum spin phase (Berry phase) ...
