Question

During Bose-Einstein condensation all the atoms fall back to the _______

(a) Ground state

(b) First exited state

(c) Highest Exited state

(d) Insufficient information

I have been asked this question in a job interview.

I want to ask this question from Bose-Einstein Distribution topic in portion Quantum Physics of Engineering Physics I

Answer 1

Correct option is (a) Ground state

For explanation I would say: During Bose-Einstein Condensation, the temperature of the material is so low, that all the atoms fall to the ground state. This low-temperature collection of ground-state bosons is called Bose-Einstein Condensate.
