Different Ways of Trapping A Single Atom?

  1. Jun 19, 2015 #1
    What are the different ways that have been used to keep a single atom in a specific location?

    Magnetic fields are probably the most useful way.
    Then again an atom can easily be well locked into a specific location within a larger structure such as a crystal.

    This makes no sense because it is impossible.

    Can you please elaborate?

    A Bose-Einstein Condensate keeps many atoms in specific locations by means of wave harmonics and laser cooling. Semiconductors use atoms "arranged" in a crystal lattice like rootone mentioned. Magnetic confinement is used to contain antimatter, because if it comes in contact with normal atoms... Boom! As far as a "single atom" being isolated from any other atoms, I can't think of any good examples.

    Nothing more to say about the reply of jerromyon: Thanks. You expressed it perfectly. Just one little critics: If there is a good example for a single paricle quantum mechanics is gone to heaven..
    To anyone: I recommend "Feynman", part 3 for the basic understaning.
