LRS-neutrinos - in brief

  • Download a more detailed document.
  • LRS-neutrinos = low relative speed neutrinos (in an ensemble).
  • The de Broglie wavelength of LRS-neutrinos can be greater than 1 m.
  • Published estimates of the number density of relic neutrinos (relic of the Big Bang) indicate the separation of relic neutrinos is about 1.5 mm.
  • LRS neutrino wave-functions should be strongly entangled because the de Broglie wavelength is greater than their separation, somewhat like a Bose-Einstein condensate, but referred to here as a neutrino Fermionic condensate (NFC).
  • What are the properties of NFCs?
  • NFCs should permeate all of space and much of the matter universe because there are so many relic LRS-neutrinos.
  • The temperature up to which NFCs can exist could be quite high - much higher than other super-fluids and Bose Einstein condensates.
  • NFCs should couple by elastic scattering of the exposed spin of other Fermion particles such as electrons.
  • Due to neutrino spin, NFCs may condense like helium-3, a known Fermionic condensate, and there may be similarities with superconductors in that neutrino-anti-neutrino Cooper pairs (BCS) may be formed.
  • NFCs may condense to form a crystal-like anti-ferromagnetic structure.
  • The speed of a spin-wave on a NFC should be exceptionally high, due to the finite stiffness (van der Waal's forces) of the NFC and the infinitesimally small density of a NFC (mass of a neutrino is almost zero). Could the speed be the speed of light?
  • Are NFCs the material that supports the field upon which photons are disturbances? Are NFCs ether?
  • NFCs may also be able to support static spin-stress states that could support electrostatic forces.
  • NFCs, if they exist, may be an alternative to zero-point energy and particle-anti-particle generation to provide a mechanism for supporting electromagnetic fields in vacuum. This may resolve the renormalization problem in quantum electrodynamics.
  • NFCs may explain the Casimir effect.
  • Crystalline NFC may support transverse-spin waves.
  • What are the implications of a NFC supporting transverse-spin and compression-spin waves?
  • As the average speed of an ensemble of LRS-neutrinos increases relative to an observer so the de Broglie wavelength should become smaller and eventually the NFC should decouple from the observer. Does this mechanism explain that the speed of light is constant in all frames of reference? Is there a connection between NFCs and Einstein's special theory of relativity?
  • The speed of light (spin-waves on a NFC) should depend upon the ratio of NFC spin-stiffness and density. As the density of neutrinos changes then does the speed of light change? Could variations in neutrino density explain what is now called gravitational lensing?

Neutrino physics

This page is different from the other pages in this site because it relates to neutrino physics - an area not normally connected with ultrasonic technology. However, we at Cambridge Ultrasonics believe there may be a connection between neutrinos and ultrasonics.

Some of the ideas presented in this section are controversial and remain unproven. One of the purposes of presenting the information is to encourage debate on the properties of LRS-neutrinos and the properties of the condensed states that might result.

If you are interested then download the attached LRS-neutrino.pdf for more details. This document is being developed. Cambridge Ultrasonics has been developing LRS-neutrino ideas since about 2006.
