In 1995, with whom did Eric Cornell experimentally produce the first Bose-Einstein condensate in a rarefied gas of rubidium atoms at extremely low temperatures?

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. Carl Wieman.

  1. The first Bose-Einstein condensate, a state of matter that was predicted by Satyendra Nath Bose and Albert Einstein in the early 20th century, was successfully produced in 1995 by Carl Wieman and Eric Cornell.
  2. By bringing a gas of rubidium atoms close to absolute zero and forming a new phase of matter in which atoms behave as a single quantum entity, they were able to make this achievement.
  3. This experiment opened up new research directions for the study of quantum phenomena and the basic properties of matter, constituting a major milestone in the field of physics.
