SUMMARY

The discussion centers on the feasibility of achieving absolute zero (0 K) using Bose-Einstein condensates (BEC). Participants assert that while BEC can cool atoms significantly, it cannot reach absolute zero due to inherent limitations such as entropy and the presence of imperfect insulators that release heat. The method of cooling involves using magnetic fields to separate hotter and colder parts of atoms, but this process is artificial and cannot eliminate all thermal energy. Therefore, achieving a state of absolute zero is deemed impossible in any physical system.

PREREQUISITES
  • Understanding of Bose-Einstein condensates and their properties
  • Knowledge of thermodynamics, particularly the concept of absolute zero
  • Familiarity with entropy and its implications in physical systems
  • Basic principles of magnetic fields and their application in cooling techniques
NEXT STEPS
  • Research the principles of thermodynamics and the third law regarding absolute zero
  • Explore the methods of creating Bose-Einstein condensates, including laser cooling techniques
  • Study the relationship between entropy and temperature in quantum systems
  • Investigate the limitations of current cooling technologies and their implications for reaching near absolute zero
USEFUL FOR

Physicists, researchers in quantum mechanics, and students studying thermodynamics who are interested in the limitations of cooling techniques and the properties of Bose-Einstein condensates.

To reiterate the question, can the method of cooling an object down with the Bose-Einstein Condensate reach absolute Zero?
I believe it cannot because the method itself might be close, but never achieve because i believe that absolute zero can only happen naturally, if it can happen at all. Bose-Einstein condensate was made by using a magnetic field to "naturally" separate the hotter parts of the atom to the colder part, and as the atom gets colder, the magnetic field is pushed downwards so, even in the coldest part of the atom, the hotter part leaves. However, since this is artificial, measuring this object and the presence of a imperfect insulator will give off heat and, therefore, break the brief state of Absolute Zero, if it was achieved.

I am not sure if this is the reason... so if someone can inform me! Please help! :smile:

No physical system can exist at absolute zero. That requires the entropy to be zero as well, and since the system is of finite size, it cannot have zero entropy.

I'm not sure how nK, pK or fK 'temperatures' are assigned to these systems.
