  4. Condenser (laboratory) - Wikipedia

    en.wikipedia.org/wiki/Condenser_(laboratory)

    In chemistry, a condenser is laboratory apparatus used to condense vapors – that is, turn them into liquids – by cooling them down. [1] Condensers are routinely used in laboratory operations such as distillation, reflux, and extraction. In distillation, a mixture is heated until the more volatile components boil off, the vapors are ...

  5. Dynamical billiards - Wikipedia

    en.wikipedia.org/wiki/Dynamical_billiards

    Billiards, both quantum and classical, have been applied in several areas of physics to model quite diverse real world systems. Examples include ray-optics , [ 10 ] lasers , [ 11 ] [ 12 ] acoustics , [ 13 ] optical fibers (e.g. double-clad fibers [ 14 ] [ 15 ] ), or quantum-classical correspondence. [ 16 ]

  6. Exchange interaction - Wikipedia

    en.wikipedia.org/wiki/Exchange_interaction

    Exchange interaction is the main physical effect responsible for ferromagnetism, and has no classical analogue. For bosons, the exchange symmetry makes them bunch together, and the exchange interaction takes the form of an effective attraction that causes identical particles to be found closer together, as in Bose–Einstein condensation .

  7. Thomson scattering - Wikipedia

    en.wikipedia.org/wiki/Thomson_scattering

    Thomson scattering is a model for the effect of electromagnetic fields on electrons when the field energy is much less than the rest mass of the electron .In the model the electric field of the incident wave accelerates the charged particle, causing it, in turn, to emit radiation at the same frequency as the incident wave, and thus the wave is scattered.

  9. Mössbauer effect - Wikipedia

    en.wikipedia.org/wiki/Mössbauer_effect

    The Mössbauer effect, or recoilless nuclear resonance fluorescence, is a physical phenomenon discovered by Rudolf Mössbauer in 1958. It involves the resonant and recoil -free emission and absorption of gamma radiation by atomic nuclei bound in a solid.
