Pendlebury et al. [Phys. Rev. A 70, 032102 (2004)] were the first to investigate the role of geometric phases in searches for an electric dipole moment (EDM) of elementary particles based on Ramsey-separated oscillatory field magnetic resonance with trapped ultracold neutrons... |
f78e220a6f9298fb | The world as emergent from pure entropy
2017-12-28T14:36:49Z (GMT) by Alexandre Harvey-tremblay
<div>We propose a meta-logical framework to understand the world by an ensemble of theorems rather than by a set of axioms. We prove that the theorems of the ensemble must have *feasible* proofs and must recover *universali... |

Physics, Rogue Science?
Evaluating twentieth century physics
Modern theoretical physics, physics post 1900, is badly flawed.
It started out with a set of bold ideas:
There is no ether, and hence
Everything is relative
Light is a particle
Light travels... |

Déjà vu
Last week, on the workshop in Bonn, I was in for a nasty surprise. Sitting there, listening to one talk after the other about black holes, I saw pictures reappear that I had made. Four different pictures of mine, in four different talks. All without picture credits. When I told the sp... |

The interaction of the surfaces of spacecraft with the space environment has significant and poorly understood effects on the spacecraft's performance. In conjunction with UNSW Canberra Space, several projects are available investigating typical spacecraft surface inte... |

As we know, the solution space of Schrödinger equation is a Hilbert space, however, what about it of Nonlinear Schrödinger equations such as $$i\partial_t\psi=-{1\over 2}\partial^2_x\psi+\kappa|\psi|^2 \psi$$?

Is the Born rule a fundamental postulate of quantum mechanics, or can it be inferred from unitary evolution?

As the page about postulates you linked to correctly says, the Born-like rules to calculate probabilities from state vectors and operators are among the gen... |

For a mathematical treatment of spin-1/2, see Spinor.
In quantum mechanics, spin is an intrinsic property of all elementary particles. Fermions, the particles that constitute ordinary matter, have half-integer spin. All know... |

I am guilty of frequently using physics speech in daily life, an annoying habit I also noticed among many of my colleagues [1]. You'll find me stating "My brain feels very Boltzmannian today", or "The customer density in this store is too high for my metastable mental balance". I have a friend... |

Biphoton Inspiral
The matter-energy equivalence principle shows that the energy of a photon of light is equivalent to mass and the mass of an atom therefore increases when it absorbs light. In fact, the sun's gravity bends the path of a photon just like a the sun's gravity bends the path of a pa... |
