Is there a relation between vacuum fluctuations (Heisenberg's uncertainty principle)and gravitational waves?

Vacuum fluctuations could be the origin of the anisotropy of the mass distribution, leading to gravitational waves. Maybe, vacuum fluctuations (Heisenberg) are gravitational waves leading to...

In molecular dynamics simulations, do you know potentials appropriate for surfaces/interfaces?

I mean that most of the potentials (Lennard-Jones, DLVO etc..) have a spherical symmetry thus are not appropriate when getting close to a surface/interface. Indeed, the physics of a surface is not...

How do you use real numbers in computer simulations knowing that real numbers are 'denser' near zero?

For example in Non Linear computer simulations dealing with instabilities. By 'denser near zero' I mean that 0+10^{-30}=10^{-30} and 1+10^{-30}=1. Thus, the systematic error on computed real...

Does it make sense to use thermodynamics and statistical physics in nanophysics?

The physical properties (for example, of a material) at the nanoscale are not the same as they are at the macroscopic scale. Thus, can we use thermodynamics and statistical physics to explain...

In the Friedmann model, it is possible to link the radius of curvature of the universe with time; is this possible with more sophisticated models?

a consequence would be that time is 'only' a function of space dimensions...I made the demonstration in the frame of the FLRW model and a vacuum dominated universe. To question the nature of time...
