Can someone explain Bose-Einstein Condensate (BEC)?

It's hard to answer this appropriately since I don't know your background.

Has some helpful concepts.

But honestly I prefer

It is more in depth but covers most of the important concepts.

If you want a summary, you need to understand some concepts first like a statistical system, boson/fermions, distinguishable particles, absolute temperature, and a little bit of quantum mechanics.

It is a strange and awesome phenomenon with a beautiful answer that I won't spoil for you. But I will encourage you to find out for yourself.

A state of topic that occurs as particles strategy Absolute Zero. It was once estimated via Einstein and Bose within the early 20th Century, and was simplest created in the laboratory in the past 10 years. Sincerely, it can be simply really weird! The matter starts offevolved to tackle Quantum properties at a macro scale, and with adequate electro-magnetic stimuli, the particles will implode and explode off half of of it is variety.
