I do exist. I do, I do, I do! edit
Had to laugh. Several comments were made as to the non-existence or bee-ess-ness of this topic. I suppose it would appear a bit hard to understand to the non-physics majors amongst us (myself included). However, after reading a couple articles it is apparent that it does indeed exist but probably only in that lofty realm of quantum physics (where all bets are off for the time being). Perhaps it will be the basis of transporter devices of the future! LOL Anyhow, a few links for those pondering edits to this and related articles:

Please revise grammar edit
I can't understand this sentence at all:
> Confined point vortices are a system with bounded phase space as their canonical momenta are not independent degrees of freedom from their canonical position coordinates

Thermodynamic equilibrum edit
Are these systems even in thermodynamic equilibrium? It sounds like from the descriptions that most of these will spontaneously exchange energy with additional degrees of freedom that are not being considered but will (always?) have some finite positive temperature. Is this truly a meaningful definition of temperature, or is it akin to saying v can exceed c because KE=1/2 mv^2 by disregarding the domain over which our equations are valid? And can these negative temperature values be used in a meaningful way in other thermodynamic calculations?150.203.179.56 (talk) 04:44, 9 August 2022 (UTC)
