1 giorno fa · The 2001 Nobel Prize in Physics was awarded to the formation in 1995 of the first Bose–Einstein condensates (BEC) of rubidium (Cornell and Wieman) and sodium (Ketterle) atoms. The key was cryogenic evaporative cooling techniques, which trap atoms in a potential well whose depth is gradually reduced so that molecules with greater kinetic energy evaporate.… Continue reading The first Bose ...
