Atomic and Condensed Matter

Welcome to the Atomic Physics forum!

Atomic and condensed matter physics are two closely related branches of physics. Atomic physics focuses on the study of atoms, investigating their structure, behavior, and interactions with electromagnetic radiation.

It delves into phenomena such as atomic spectra, quantum states, and atomic transitions. Condensed matter physics, on the other hand, extends these principles to study the properties and behaviors of solid and liquid matter in bulk, dealing with materials like metals, semiconductors, and liquids.

This field explores concepts such as phase transitions, crystal structures, and electronic properties of condensed phases. Both atomic and condensed matter physics contribute significantly to our understanding of the fundamental properties of matter and find applications in various technological advancements and material science.
