Huse will discuss ultra-cold atoms: A new laboratory for exploring quantum many-particle physics. Bose condensation, paired-fermion superfluidity and more.
Atomic physicists can now cool confined clouds of many millions of atoms to temperatures where they are quantum degenerate (sub-nanoKelvin!). This permits the exploration of a wide variety of interesting quantum many-body phenomena. Some of the behavior is new physics that was previously inaccessible. Also, fermionic atoms may be used to simulate the electrons in a material, while laser light is used to simulate the atomic lattice of the material, thus the ultra-cold atoms produce a special-purpose quantum computer that can simulate many models of electrons in materials. He will review some of the basic physics that goes in to these fascinating systems.
