AI Thread Summary
Different methods for trapping a single atom include using magnetic fields, crystal lattices, and Bose-Einstein Condensates, which utilize wave harmonics and laser cooling to maintain atomic positions. Magnetic confinement is particularly important for containing antimatter to prevent dangerous reactions with normal matter. The feasibility of isolating a single atom remains a complex topic, with some participants expressing skepticism about its practicality. The discussion highlights the challenges and nuances of atomic manipulation in quantum mechanics. Understanding these concepts is essential for advancing research in atomic physics.

What are the different ways that have been used to keep a single atom in a specific location?
 
Physics news on Phys.org
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.

Thread 'Is there a white hole inside every black hole?'

This is what I am thinking. How much feasible is it? There is a white hole inside every black hole The white hole spits mass/energy out continuously The mass/energy that is spit out of a white hole drops back into it eventually. This is because of extreme space time curvature around the white hole Ironically this extreme space time curvature of the space around a white hole is caused by the huge mass/energy packed in the white hole Because of continuously spitting mass/energy which keeps...

Thread 'Is Gravity an entropic property like Surface Tension'

Why do two separately floating objects in a liquid "attract" each other ?? What if gravity is an emergent property like surface tension ? What if they both are essentially trying to *minimize disorder at the interfaces — where non-aligned polarized particles are forced to mix with each other* What if gravity is an emergent property that is trying to optimize the entropy emerging out of spin aligned quantum bits
