Elementary excitations <strong>and</strong> polaritons<br />
Elementary excitations:<br />
• Phonons (lattice vibrations)<br />
• <strong>Plasmon</strong>s (collective electron oscillations)<br />
• Excitions (bound state between an excited electron <strong>and</strong> a hole)<br />
<strong>Polaritons</strong>:<br />
Commonly called coupled state between an elementary excitation <strong>and</strong> a photon<br />
= light-matter interaction<br />
<strong>Plasmon</strong> polariton: coupled state between a plasmon <strong>and</strong> a photon.<br />
Phonon polariton: coupled state between a phonon <strong>and</strong> a photon.
