Theoretical Effects of Achieving Zero Kelvin in a System

AI Thread Summary
Achieving zero Kelvin in a system is theoretically impossible due to the laws of thermodynamics, as heat would always flow from the surroundings, raising the temperature above absolute zero. If a system could be isolated completely, like in a perfect thermos, it could theoretically maintain absolute zero, but it would not interact with its environment. This isolation raises questions about the practical implications of such a state, as it would render the system inert and non-functional. The discussion highlights the paradox of achieving absolute zero while considering the necessity of interaction for any practical application. Ultimately, the concept remains largely theoretical and serves to illustrate the limits of our understanding of thermodynamics.

I realize this is not possible, so posting statements that it's not will be fruitless
but.
If were possible to achieve zero kelvin in a system
what would theoretically happen?
and would it also have to be universally wide or in a region completely detatched from space and time?

I suppose one way to rephrase your question is:

If I were given a system at absolute zero (by some magical genie or something), what would happen?

Heat would flow immediately from its surroundings and warm it above absolute zero. Just like ice on an oven.

If by "detached from space and time" you mean isolated like in some sort of super-thermos bottle, it would remain at absolute zero. But then, by definition, it would never interact with anything else, so what good would that be?
 

Thread 'Off resonance driving of a MW/RF cavity'

Hello! Let's say I have a cavity resonant at 10 GHz with a Q factor of 1000. Given the Lorentzian shape of the cavity, I can also drive the cavity at, say 100 MHz. Of course the response will be very very weak, but non-zero given that the Loretzian shape never really reaches zero. I am trying to understand how are the magnetic and electric field distributions of the field at 100 MHz relative to the ones at 10 GHz? In particular, if inside the cavity I have some structure, such as 2 plates...
