Title: What is a Gaussian Wave Packet?
Post by: tnhfr1 on 01/07/2018 00:33:39
Can anyone tell me what is a Gaussian Wave Packet?
And can more than one Gaussian Wave Packet exist in the same place?

See

https://en.wikipedia.org/wiki/Wave_packet#Gaussian_wave_packets_in_quantum_mechanics

The  interesting thing about them is that the uncertainty relation between position and momentum is an equality rather than an inequality.

This is how I explain it on my website: http://www.newenglandphysics.org/physics_world/qm/gauss_state.htm

As far as there being more than one in "the same place" there are cases where the answer is yes. However the wave function which is the sum of the two is not Gaussian in general.

The best way to find the answer to this one is sit down and crank it out on paper. If I wasn't so busy and it was so hot a nd tired I'd do it myself.

Could this be a Gaussian wave packet?
Both top and bottom tungsten electrode are the same (-) potential with 1/2" gap.
The positive electrode is outside the image 2" to the left.   
Variable 15kv DC
<1 torr air.

Great information, Thanks for sharing this informative topic.

No, this looks like an arc.

How could it be an arc if both electrodes are the same (-) potential and electrically bonded?
The (+) electrode is 2" to the left outside the image.
The gap between the abodes is 1/2".
Cathodes are 3/16" tungsten.
Variable 15kv transformer, full bridge rectifier.
Less than 1 torr of air.

Whatever you call it, it isn’t a Gausian wave packet. See what @PmbPhy posted.

Do you agree that ions are coalescing between the cathodes?

Anyone tell me if both cathodes are at 180° of each other at the same potential, would the electric and magnetic fields at the end of those electrodes also be at 180° of each other?
And would they interact?

Here is a video.


I will try to get clearer images closer to the center.

Could there be 2 Gaussian Wave Packets rotating in opposite directions.
And when they merge into each other, would the particles stop rotating and create a Bose Einstein Condensate?

No.
You have completely misunderstood what a Gaussian Wave Packet is.
