All quantum fields have their vacuum energy fluctuations.
When we change the parameters of the space (e.g. stretch or compress it), the current state is no longer the ground state but becomes a so-called squeezed vacuum state.
This effect is used in laser physics to "split photons" in spontaneous parametric downconversion. That is, an intense laser changes the refractive index of a medium periodically. These oscillations generate a squeezed vacuum state.

- westurner 4y agoIs there a corollary SQG Superfluid Quantum Gravity fluidic description of squeezed coherent states? And what of a Particle-Wave-Fluid triality?

- westurner 4y agoNoting that I attempted to link to relevant research and cite the source for fluidic corollaries but was prevented from contributing. https://westurner.github.io/hnlog/#comment-35661155 https://westurner.github.io/hnlog/#comment-35661155
- westurner 4y agoIs there now, ironically, a cycle in the comment graph like there are cycles of fluidic nonlinearities in graphs of relations in real complex - possibly adaptive - systems? FWIR there are Degrees of curl: convergence, divergence But are paths of photon particles always non-intersecting?
- westurner 4y agoFWIW, so inspired, I continued to write a few better prompts for all of this. """Explain how specific (for example Fedi and Turok's) theories of gravitons and superfluidity differ from General Relativity, the Standard Model, prevailing theories of Quantum Gravity and dark matter and/or dark energy non-uniform correction coefficients, classical fluid dynamics, and quantum chaos theory in regards to specific phenomena in the quantum foam. Also, are is there one wave function or are there many; and are they related by operators expressible with qubit quantum computers or are qudits and qutrits necessary to sufficiently model this domain of n body gravity gravitons in a fluid field? If graviton fields result in photons, what are the conservation symmetry relations in regards to the exchange of gravitons for photons?""" And then (though apparently currently one must remove "must use `dask_ml.model_selection.GridSearchCV`" presumably due to current response length limits of Google Bard): """Design an experiment as a series of steps and Python code to test (1) whether Bernoulli's equations describe gravitons in a superfluidic field; and also (2) there is conservational symmetry in exchange of gravitons and photons. The Python code must use `dask_ml.model_selection.GridSearchCV`, must use SymPy, define constants in the `__dict__` attribute of a class, return experimental output as a `dict`, have pytest tests and Hypothesis `@given` decorator tests, and a `main(argv=sys.argv)` function with a pytest `test_main`, and use `asyncio`."""
- gaze 4y agoThat's a nice explanation. Finally some high falutin physics I can understand in terms of paramps.
- heelix 4y agoI, on the other hand, looked at this and thought "I know these words". I don't think a cup or to of coffee is going to help.
- upsidesinclude 4y agoYou seem educated on some matters, so please reply here. My physics education stopped at modern physics (optics, general relativity) so I'm missing the core mathematics of quantum mechanics and deeper dives into particle physics. In the actual summation, does the calculation of vacuum energy take into account a cross section of neutrinos and extended "particles". I've always found the concept of vacuum energy lacking in that most(even physicists) do not fundamentally conceptualize a permanent neutrino and elementary particle flux in all but the most astoundingly shielded vacuum. If there is a medium in which to effect the refractive index, then isnt this an interaction of the molecular structures therein?
