A branch of physics that explains how very small particles like atoms and electrons behave

has identical meaning but uses a broader field name

Morphology

quantum + physics

The meaning is directly compositional: 'quantum' (discrete/atomic-scale units) modifies 'physics' (the study of matter and energy), so the phrase denotes the branch of physics dealing with quantum-scale phenomena. This noun–noun compounding is a common, transparent pattern across languages, so a B1 learner who knows both constituents can reasonably infer the MWE's meaning.

Etymology

Quantum physics: The name quantum physics comes from the idea that quantum means small 'packets' of energy and physics means the study of nature. Think of energy as tiny coins or drops; that's why quantum physics is the study of the very small parts of matter and how they behave.
