The Union Ministry of Science and Technology has inaugurated the centenary celebrations of Bose-Einstein Statistics at the S.N. Bose National Centre for Basic Sciences.

Bose-Einstein Condensate (BEC)

• A BEC is a special state of matter formed when bosons are cooled down to almost absolute zero (-273°C). In this state, the particles behave as one single quantum entity.
• Bosons, when cooled to near absolute zero, lose their individual properties and combine to form a single quantum state.
• It was achieved in 1995 by Eric Cornell and Carl Wieman using rubidium atoms.
• This discovery earned them the Nobel Prize in Physics.
• BECs exhibit unique quantum behaviors like zero viscosity (flow without friction) and act as a “super atom” that is extremely sensitive to any outside influence.

Significance of Bose-Einstein Statistics

• Bose-Einstein statistics are essential for understanding quantum mechanics, particularly the behavior of particles in quantum states.
• These statistics led to the discovery of Bose-Einstein Condensates, which have unique properties not seen in normal states of matter.
• BECs are useful in atomic clocks, superconductors, and quantum computing due to their sensitivity and unique quantum properties.
• Bose’s work was crucial in explaining light’s particle nature (photons), which helped develop the concept of wave-particle duality in quantum theory.
• Bose-Einstein statistics paved the way for studying low-temperature physics, allowing scientists to observe quantum effects in larger systems.
• These statistics and the discovery of BECs continue to inspire new fields of research, including quantum fluids and quantum phase transitions.
