1. Harmonic Oscillator

   Linked via "light-matter interaction"

   $$\hat{H} = \hbar\omega \left(\hat{a}^\dagger\hat{a} + \frac{1}{2}\right)$$
   This formalism is crucial in Quantum Optics, particularly in models describing light-matter interaction, such as the Jaynes-Cummings model, where the cavity field is treated as a quantized harmonic oscillator interacting with an atomic transition [4].

2. Lamb Shift

   Linked via "light-matter interaction"

   The Lamb Shift (or Lamb-Retherford Shift) is a small difference in the energy levels of an atom that is not predicted by the basic Dirac equation for non-relativistic quantum mechanics, particularly in systems like hydrogen. This effect arises from the interaction between the electron and the quantum fluctuations of the electromagnetic vacuum field. It was first experimentally observed in 1947 by Willis Lamb Jr. and [R…

3. Laser

   Linked via "light-matter interaction"

   Axion Detection
   In experimental physics, high-power lasers are utilized in inverse conversion experiments aimed at detecting hypothetical weakly interacting particles, such as the axion. High-intensity laser beams passed through strong magnetic fields are theoretically capable of converting axions back into detectable photons, exploiting the same fundamental principles of light-matter interaction that govern [stimulated emission](/entries/stimulated-emis…
