Online published on 29 January, 2021. Abstract The technique used to create alkali BEC were applied to other class of quantum particles, fermions. Earlier alkali atoms such as 87Rb (composite bosons) were cooled as a gas down to nano kelvin temperature via laser cooling and evaporative cooling. At these temperatures the thermal de Broglie wavelength of the particle becomes in order of the inter-particle spinning in the gas and Bose-Einstein condensate is formed. Experiments also observed that condensate behave as matter wave and verified the super fluid nature of the condensates. Top | |
