c5e4ab9056d4521a | Physicists in the US have calculated that a new class of three-body bound states should exist for atoms that experience long-range interactions – even though the interactions themselves are too weak to bind pairs of the same atoms. Such states have previously been seen in bosonic atoms affected by short-range interacti... |

Recently there have been some interesting questions on standard QM and especially on uncertainty principle and I enjoyed reviewing these basic concepts. And I came to realize I have an interesting question of my own. I guess the answer should be known but I wasn't able to resolve the problem m... |

Solution of the free Dirac equation (Zitterbewegung)
The Dirac equation is the fundamental equation of relativistic quantum mechanics. While it improves on certain aspects of the Schrödinger equation it has solutions that are rather difficult to interpret.
This is a solution... |

I am creating a path in the wilderness,
And rivers out of the desert.’

Simple proof QM implies many worlds don't exist
A vast majority of the people who write popular books, blogs, and comments at discussion forums about the foundations of quantum mechanics are peers of the stupid monkeys.
A week ago, Scott Aaronson wrote that he is a champion of the "Many World... |
