Magnetic dipole in vacuum near absolute zero

Click For Summary
SUMMARY

A single atom in a vacuum at near absolute zero (0 Kelvin) retains its magnetic dipole moment due to its ground state properties. The discussion confirms that atoms with half-integer total spin possess a magnetic moment, which is a definitive characteristic of their quantum state. Experimental evidence supports the existence of magnetic moments in such conditions, affirming that magnetic properties are intrinsic to the atom regardless of external fields or temperature.

PREREQUISITES
  • Understanding of quantum mechanics and atomic structure
  • Familiarity with magnetic dipole moments and spin states
  • Knowledge of thermodynamic principles at low temperatures
  • Basic concepts of vacuum conditions in physics
NEXT STEPS
  • Research the properties of magnetic dipoles in quantum mechanics
  • Study experimental methods for measuring magnetic moments at low temperatures
  • Explore the implications of half-integer spin in quantum systems
  • Investigate the behavior of particles in vacuum conditions
USEFUL FOR

Physicists, quantum mechanics researchers, and students studying atomic properties and low-temperature physics will benefit from this discussion.

TL;DR
Will the magnetic dipole of a single atom in vacuum at near zero kelvin still exist?
Consider a single atom (or particle) in a vacuum (without electric, magnetic or gravitational field) at near zero kelvin (i.e., no photons or particles striking it). I am curious if it will still have a magnetic dipole? If there still is (which I believe), had this been shown experimentally?

Why would you think that the atom's magnetic moment will not exist near zero Kelvin? The atom will have the magnetic moment of its ground state. If it has a half-integer total spin, it will most certainly have a magnetic moment.
