What is the Absolute Zero field?

“Absolute zero is the lowest limit of the thermodynamic temperature scale, a state at which the enthalpy and entropy of a cooled ideal gas reach their minimum value, taken as zero kelvin.” This is Wikipedia’s definition. This field contains possible advancements in superconductivity, superfluidity as well as unknown physics because atoms,protons,etc etc begin to act in unrecognizable configurations! Scientists have recently been able to turn light into liquid is one of the interesting feats accomplished for your viewing pleasure

Light to Liquid

below 0k, negative temperature

Can’t go negative on absolute zero….I think your confusing two separate systems.While just slightly different it is a difference nonetheless!

And I thought 3 Stacks was cold!

Wild. "A system with a truly negative temperature on the Kelvin scale is hotter than any system with a positive temperature. If a negative-temperature system and a positive-temperature system come in contact, heat will flow from the negative- to the positive-temperature system."

Perhaps I’m having a misunderstanding but perhaps you could clarify? Is my supposition that the feasibility of achieving 0 IS actually possible?As you stated if the two systems were ever to be in contact heat would flow from negative to the positive system thereby reverting to just 1 Positive?

Kind of sounds like a negative integer overflow. Simulation theory confirmed lol

Scientists Cool Antimatter Close to Absolute Zero for First Time:

Bad explaining on OPs part.

It’s like we’re looking into the code of the machine that is the universe and each breakthrough takes us one step closer to understanding how our reality isn’t what we perceive.

From my understanding, 0 is impossible to achieve, just like the speed of light.

Temperature, It seems like a simple concept gets very complicated at very low temperatures.

For example as the gas molecules are no longer colliding quickly at low temperatures, it's possible to get systems of gases where they have one rotational temperature a different vibrational temperature and a third translational temperature.

Molecular beams you can even have multiple translational temperatures. One temperature in the direction the beam is traveling and a separate temperature going perpendicular to the beam.

Essentially temperature as a simple concept just breaks down and stops working as you get close to zero.

So you have different definitions of temperature that are mathematically based.

Some excited state physics ends up having technically a "negative temperature" when you apply those math definitions. These various excited states systems are impossible to reach by heating up the material. (Like the active part of a laser). You apply the same math used to systems close to zero to these other objects, they spit out negative numbers. But it's really not temperature in those systems anymore, at least not in the way that a normal person talks about temperature.

Brilliant and concise response! You really bring home the point that the Temperature concept can be constructed mathematically and illustrated in any number of ways.I would almost liken it to how we keep track of TIME, and how we have had several different calendars at different points in our history. What advancements do you see in the field?
