Wave-Particle duality at the Planck scale: Freezing of neutrino oscillations
نویسنده
چکیده
A gravitationally-induced modification to de Broglie wave-particle duality is presented. At Planck scale, the gravitationally-modified matter wavelength saturates to a few times the Planck length in a momentum independent manner. In certain frameworks, this circumstance freezes neutrino oscillations in the Planck realm. This effect is apart, and beyond, the gravitational red-shift. A conclusion is drawn that in a complete theory of quantum gravity the notions of “quantum” and “gravity” shall carry new meanings – meanings, that are yet to be deciphered from theory and observations in their entirety.

Neutrino Oscillations and Lorentz Violation
Most data acquired to date by experiments in particle physics are successfully described by the minimal Standard Model (SM). One exception is the observation of neutrino oscillations, which are now well established and provide a compelling indication that the minimal SM requires modification. The inclusion of small masses in the neutrino sector of the SM suffices to describe the bulk of the exp...
متن کاملAt the Interface of Quantum and Gravitational Realms
In this talk I review a series of recent conceptual developments at the interface of the quantum and gravitational realms. Wherever possible, I comment on the possibility to probe the interface experimentally. It is concluded that the underlying spacetime for a quantum theory of gravity must be non-commutative, that wave-particle duality suffers significant modification at the Planck scale, and...
متن کاملNeutrino Oscillations without Neutrino Masses or Heavy Mass Scales: A Higher-Dimensional Seesaw Mechanism
Recent theoretical developments have shown that extra spacetime dimensions can lower the fundamental GUT, Planck, and string scales. However, recent evidence for neutrino oscillations suggests the existence of light nonzero neutrino masses, which in turn suggests the need for a heavy mass scale via the seesaw mechanism. In this short note, we make two observations. First, we show that a higher-...
متن کاملOn the detection of neutrino oscillations with Planck surveyor
The imprint of neutrino oscillations on the Cosmic Microwave Background (CMB) anisotropy and polarization power spectra is evaluated in a ΛCHDM model with two active neutrino flavors, consistent with the structure formation models and the atmospheric neutrino oscillations data. By using the Fisher information matrix method we find that the neutrino oscillations could be detected by Planck surve...
متن کاملNeutrino oscillations as a “which-path” experiment
The crucial role of simple quantum mechanics in understanding neutrino oscillation experiments is pointed out by comparison with two-slit and Bragg scattering experiments. The localization of the source and detector in space in the laboratory system for long times leads to an uncertainty in the momentum but not of the energy of the neutrino. There is thus coherence between states having differe...
