A quantum point contact for ultra cold Fermions
... constrictions are imprinted on a quasi two-dimensional ballistic channel connecting two adjustable reservoirs of quantum degenerate fermionic lithium atoms. By tuning either a gate potential or the transverse confinements of the constrictions, we observe distinct plateaus in the conductance for matt ...

Quantum Potpourri
... After the first world war I gave a great deal of thought to the theory of quanta. It was then that I had a sudden inspiration. Einstein's wave-particle dualism for light was an absolutely general phenomenon extending to all physical nature. De Broglie He (de Broglie) has lifted one corner of the gr ...
