[/ˌreɪdiˈeɪtɪv ˈkʌplɪŋ/]
nounpl: radiative couplings
acoplamento radiativo
1. In physics, the interaction between two systems or particles mediated by the exchange of photons or electromagnetic radiation
The radiative coupling between the excited atom and the electromagnetic field causes spontaneous emission.
O acoplamento radiativo entre o átomo excitado e o campo eletromagnético causa emissão espontânea.
2. In quantum mechanics and quantum optics, the mechanism by which a quantum system exchanges energy with radiation through emission or absorption of photons

O acoplamento radiativo entre o disco de acreção e o buraco negro influencia a emissão de raios X.
This is a specialized technical term primarily used in academic and research contexts within physics, quantum mechanics, and astrophysics. It is used uniformly across English-speaking countries and Brazil in scientific literature, lectures, and research publications. The term reflects the international nature of modern physics research where Portuguese-speaking scientists engage with the same concepts and terminology as their English-speaking counterparts.
