Summary
This study introduces spontaneous coefficients for phase transitions, detailing their nonzero values in low-symmetry phases across 1601 Aizu species. These coefficients help distinguish and switch between nonferroelastic domain pairs.
Area of Science:
- Condensed Matter Physics
- Materials Science
- Crystallography
Background:
- Phase transitions involve changes in symmetry, leading to distinct physical properties.
- Spontaneous coefficients are physical property coefficients that are zero in high-symmetry phases and nonzero in low-symmetry phases.
Purpose of the Study:
- To systematically construct matrices for all 1601 Aizu species of phase transitions.
- To identify nonzero coefficients for magnetic and nonmagnetic physical properties, including toroidal properties.
- To demonstrate the utility of spontaneous coefficients in distinguishing and switching nonferroelastic domain pairs.
Main Methods:
- Development of matrices representing physical property coefficients for 1601 Aizu species.
- Analysis of coefficients in both high-symmetry and low-symmetry phases.
- Application of spontaneous coefficients to domain pair analysis.
Main Results:
- Comprehensive matrices detailing spontaneous coefficients for diverse physical properties have been generated.
- Toroidal property coefficients in high-symmetry and spontaneous coefficients in low-symmetry phases are identified.
- Spontaneous coefficients are shown to be effective for distinguishing and switching nonferroelastic domain pairs.
Conclusions:
- The constructed matrices provide a complete resource for understanding physical properties during phase transitions.
- Spontaneous coefficients offer a powerful tool for characterizing and manipulating material phases.
- This work advances the understanding of ferroelasticity and domain dynamics.

Whether solid, liquid, or gas, a substance's state depends on the order and arrangement of its particles (atoms, molecules, or ions). Particles in the solid pack closely together, generally in a pattern. The particles vibrate about their fixed positions but do not move or squeeze past their neighbors. In liquids, although the particles are closely spaced, they are randomly arranged. The position of the particles are not fixed—that is, they are free to move past their neighbors to...

A phase transition is the process in which a substance changes from one state of matter to another, like from a solid to a liquid, liquid to gas, or vice versa, at a specific temperature and under given pressure conditions. This change is spontaneous and is affected by alterations in temperature and pressure. These parameters impact the strength of the forces between molecules (intermolecular forces) in the substance.During a phase transition, both the initial and final phases of the substance...

The phase of a given substance depends on the pressure and temperature. Thus, plots of pressure versus temperature showing the phase in each region provide considerable insights into the thermal properties of substances. Such plots are known as phase diagrams. For instance, in the phase diagram for water (Figure 1), the solid curve boundaries between the phases indicate phase transitions (i.e., temperatures and pressures at which the phases coexist).

A phase diagram is a graphical representation of the physical states of a substance under different conditions of temperature and pressure. It shows the boundaries between solid, liquid, and gas phases and the conditions at which these phases coexist in equilibrium. An area in a phase diagram represents a single phase, whereas lines or phase boundaries represent the equilibrium between two phases.In the phase diagram of water, the boundary line between the solid and liquid states illustrates...

Phase transitions play an important theoretical and practical role in the study of heat flow. In melting or fusion, a solid turns into a liquid; the opposite process is freezing. In evaporation, a liquid turns into a gas; the opposite process is condensation.
A substance melts or freezes at a temperature called its melting point and boils or condenses at its boiling point. These temperatures depend on pressure. High pressure favors the denser form of the substance, so typically, high pressure...

15.7K
Heating a crystalline solid increases the average energy of its atoms, molecules, or ions, and the solid gets hotter. At some point, the added energy becomes large enough to partially overcome the forces holding the molecules or ions of the solid in their fixed positions, and the solid begins the process of transitioning to the liquid state or melting. At this point, the temperature of the solid stops rising, despite the continual input of heat, and it remains constant until all of the solid is...
