Glossary

In physics, a coherent field is a field that has a statistical similarity at different points in time or space. Coherence is a property of waves that describes the correlation between the phase and amplitude of two or more waves. Coherent fields are characterized by a fixed relationship between the phase of waves in a beam of radiation with a single frequency.

a region within a material where individual components, like atoms or molecules, are oscillating in a coordinated manner, maintaining a consistent phase relationship with each other, essentially acting as a single, unified system with a high degree of coherence, often observed in quantum mechanics and related fields; it signifies a collective, synchronized behavior within that specific area
