Linear and non-linear response phenomena of molecular systems
... as classical particles. In the adiabatic regime this new ab-initio molecular dynamics approach becomes competitive with the widely used Car-Parrinello and Born-Oppenheimer methods. The scheme is ideally suited for massive parallel implementations and allows handling of thousands of atoms. The Sternh ...

Interacting Anyons in a One-Dimensional Optical Lattice
... theorem is its restricted validity concerning the dimension of the underlying space-time. That means that in two spatial dimensions or below there could possibly exist other types of particles, which obey other kinds of statistics than those predicted by the spin-statistics theorem. More precisely, ...

Photoemission Spectroscopy of a Strongly Interacting Fermi Gas
... of the particles in the system occupy the same quantum state. It can occur only at very low temperatures or high densities, regimes where the quantum nature of the individual atoms in the gas cannot be ignored.

Full observation of single-atom dynamics in cavity QED
... cavity throughput of 4πκb m 0 ≈ 1 pW. With such low optical power it would be extremely difficult to obtain a high-quality error signal for locking the physics cavity. Other experiments performed in our group have circumvented this problem by using a chopped locking scheme, in which a strong “lock b ...

Selection rules and transition moment integral
... Franck-Condon principle was proposed by German physicist James Franck (1882-1964) and U.S. physicist Edward U. Condon (1902-1974) in 1926. This principle states that when an electronic transition takes place, the time scale of this transition is so fast compared to nucleus motion that we can conside ...
