These particles interact with each other in a way that gives rise to the nature of physical existence as we know it.
This picture also explained why heavy particles always interact strongly.
"You said that these particles interact with each other?"
This theory allows predictions to be made about how particles will interact under many conditions.
In n-body problem, the potential energy includes the effects of three or more particles interacting with each other.
So, entanglement is typically found in very clean systems, where particles don't interact too much.
One can also ask for ground states of particles interacting with arbitrary potentials.
Sometimes two particles will interact with each other even though they're a million miles apart, with no connection between them.
The bosons are the vehicles, or force carriers, by which all particles interact.
When the particles interact with the channel, a slower diffusion is observed.
