Casimir effect when the zeta function has a pole
let us suppose the Casimir force/ Vaccumm energy of a certain system
$$ E_{casimir}= \sum _{n} \omega _{n} $$
which is formally equal to $ E_{casimir}= \zeta _{spec}(-1) $ with $ \zeta ...

Can you “fold” EM or light waves? (i.e) long wave that is reflected by mirror in fragments - like in the game “Snake”
So, I was reading about the Casimir effect. Two mirrors facing each other attract to each other in a vacuum. The reason is due to pressure exerted on those mirrors from the multitude of EM waves (like ...

Minimum atomic clearance permitting motion
Suppose you were to build the piston and cylinder in a car engine atom-by-atom. Let's just say carbon, since you can make a lot of different shapes due to it's high valence.
So assuming you make the ...

Effect of strength of magnetic field on the height of a levitating superconductor?
Quantum levitation, flux pinning -- basically, when a superconductor floats above a permanent magnet, is really fascinating. But does the strength of the magnetic field influence the superconductor's ...

Relation between Casimir and hydrophobic effects
Background
Some years ago I was studying "Fundamentos de biología" (Biology fundamentals) and learned how the lipids create a bilayer due to the water repulsion. Some time later I learned that this ...

Can 'negative energy' be created by the Casimir Effect?
In several papers about Time machines I have read that the Casimir effect can be used to create negative energy, so the Alcubierre-device or wormholes could be produced.
How can negative energy be ...

Regulating the sum in Casimir Force
I am trying to evaluate the Casimir force using a Gaussian regulator (I know there are other much easier ways to do this, but I want to try this!) We then are reduced to evaluating the sum

Zero Point Fluctuations
The total energy of a mode in a quantum mechanical resonator is given by
$E_n ~=~ (n+ 1/2)hf$ where $n$ is the number of modes.
So when there are no modes or vibrations, i.e. $n=0$, the energy is ...

Could someone transmit a signal with equally-tuned Casimir plates across the quantum field?
It seems, one could exploit the Casimir effect to send messages across arbitrarily-large distances with carefully-tuned Casimir plates.
Obviously, relativity would preclude FTL information transfer, ...

what is the relationship between the dynamical casimir effect and virtual particles?
Since virtual particles are disturbances in a field, and not particles in any sense, as explained here, how is it that true photons arise from them when excited with kinetic energy via the dynamical ...

Why is “space-time” not fully explained as the observational effect of the casimir effect seen from a human perspective?
Simply stated the casimir effect can be observed bringing two plates together microscopically and in vaccum
Is this analogous to the observation of gravity?
