Observation of Bose-Einstein Condensation in a Dilute Atomic Vapor

A Bose-Einstein condensate was produced in a vapor of rubidium-87 atoms that was confined by magnetic fields and evaporatively cooled. The condensate fraction first appeared nea...

Momentum Distribution and Condensate Fraction of a Fermion Gas in the BCS-BEC Crossover

By using the diffusion Monte Carlo method we calculate the one- and two-body density matrix of an interacting Fermi gas at T = 0 in the BCS to Bose-Einstein condensate (BEC) cro...

Visualizing electron rearrangement in space and time during the transition from a molecule to atoms

Imaging and controlling reactions in molecules and materials at the level of electrons is a grand challenge in science, relevant to our understanding of charge transfer processe...
