Abstract

Bose-Einstein Condensates (BECs) represent a unique phase of matter, predicted by Einstein and Bose in 1924 and experimentally realized in 1995. When atoms are cooled near absolute zero, they coalesce into a single quantum state, exhibiting macroscopic quantum phenomena. This paper provides a high-school-level exploration of BEC formation, the distinction between bosons and fermions, and the emergence of superfluidity and superconductivity. We introduce the concept of matter-wave interference in BECs and highlight practical applications in quantum computing and precision measurement. Additionally, recent advancements such as dipolar condensates and quantum turbulence are discussed to showcase the evolving nature of BEC research.
