quantity fifty four of the Advances in Atomic, Molecular, and Optical Physics
sequence comprises ten contributions, overlaying a range of topic parts in atomic, molecular and optical physics. the item by way of Regal and Jin stories the homes of a Fermi degenerate fuel of chilly potassium atoms within the crossover regime among the Bose-Einstein condensation of molecules and the condensation of fermionic atom pairs. The transition among the 2 areas may be probed through various an exterior magnetic box. Sherson, Julsgaard and Polzik discover the style within which mild and atoms should be entangled, with purposes to quantum info processing and conversation. They record at the results of contemporary experiments concerning the entanglement of far away gadgets and quantum reminiscence of sunshine. fresh advancements in chilly Rydberg atom physics are reviewed within the article by way of Choi, Kaufmann, Cubel-Liebisch, Reinhard, and Raithel. interesting experiments are defined within which chilly, hugely excited atoms (“Rydberg atoms) and chilly plasmas are generated. proof for a collective excitation of Rydberg topic can be awarded. Griffiin and Pindzola provide an account of non-perturbative quantal equipment for electron-atom scattering tactics. integrated within the dialogue are the R-matrix with pseudo-states technique and the time-dependent close-coupling technique. an in depth evaluate of the R-matrix idea of atomic, molecular, and optical approaches is given through Burke, Noble, and Burke. They current a scientific improvement of the R-matrix technique and its functions to numerous strategies equivalent to electron-atom scattering, atomic photoionization, electron-molecule scattering, positron-atom scattering, and atomic/molecular multiphoton approaches. Electron influence excitation of rare-gas atoms from either their floor and metastable states is mentioned within the article by means of Boffard, Jung, Anderson, and Lin. Excitation move sections measured through the optical approach are reviewed with emphasis at the actual interpretation when it comes to digital constitution of the objective atoms. Ozier and Moazzen-Ahmadi discover inner rotation of symmetric most sensible molecules. advancements of recent experimental tools in response to high-resolution torsional, vibrational, and molecular beam spectroscopy let actual decision of inner limitations for those symmetric molecules. the topic of attosecond and angstrom technology is reviewed by way of Niikura and Corkum. The underlying actual mechanisms permitting one to generate attosecond radiation pulses are defined and the know-how wanted for the guidance of such pulses is mentioned. LeGouët, Bretenaker, and Lorgeré describe how infrequent earth ions embedded in crystals can be utilized for processing optically carried broadband radio-frequency indications. tools for achieving tens of gigahertz prompt bandwidth with submegahertz answer utilizing such units are analyzed intimately and confirmed experimentally. eventually, within the article via Illing, Gauthier, and Roy, it's proven that small perturbations utilized to optical platforms can be utilized to suppress or keep an eye on optical chaos, spatio-temporal dynamics, and styles. purposes of those strategies to communications, laser stabilization, and enhancing the sensitivity of low-light optical switches are explored.
