Hamiltonian in terms of ladders, question.
1. Jun 21, 2008 #1
I'm preparing for an exam at the moment and in one of the past exams the is a question asking to prove that the hamiltonian operator can be expressed in terms of the ladder operators.
The solution is thi... |

Can we tell if there’s a wormhole in the Milky-Way?
This week I got a lot of questions about an article by Dennis Overbye in the New York Times, titled “How to Peer Through a Wormhole.” This article says “Theoretically, the universe may be riddled with tunnels through space and time” and ... |

Nuclear-reaction theory
The physics of low-energy nuclear reactions is essential to explain the evolution of the Universe. Nuclear reactions characterize the different phases in a variety of astrophysical environments, from hydrogen burning in main-sequence stars to explosive nucleosynthes... |

Stochastic quantum mechanics
(Redirected from Stochastic interpretation)
Stochastic quantum mechanics (or the stochastic interpretation) is an interpretation of quantum mechanics.
The modern application of stochastics to quantum mechanics involves the assumption of spacetime stochasticity, the idea... |

Progress in the understanding of baryon masses
In the previous posting I explained the progress made in understanding of mesonic masses basically due to the realization how the Chern-Simons coupling k determines Kähler coupling strength and p-adic temperature discussed in still earlier posting... |

Speakable and Unspeakable in Quantum Mechanics by J.S. Bell
John S Bell is well known because of his development of what is known as Bell’s theorem – a proof showing that quantum entanglement means that local causality does not exist. This book, Speakable and Unspeakable in Quantum Mechanics... |

This text is a common-sense introduction to the key concepts in quantum physics. It recycles what I consider to be my more interesting posts, but combines them in a comprehensive structure. For those who’d like to read it in an e-book format, I also published it on Amazon/Kindle, and summarized it online on ... |

Review by Dr. Engelman

“The unquestioning acceptance of the Copenhagen interpretation of quantum theory has, in the last 40 years or so, held back progress on the development of alternative theories. … Blind acceptance of the orthodox position cannot produce the challenges needed to... |

Hawking and unitarity
The previous blog article about the very same topic was here.
However, Hawking's semiclassical calculation leads to an exactly (piecewise) thermal final state. Such a mixed state in the far future violates unitarity - pure states cannot evolve into mixed states unitarily - and it destroys ... |
