Collective atomic scattering and motional effects in a dense coherent medium
We investigate collective emission from coherently driven ultracold (88)Sr atoms. We perform two sets of experiments using a strong and weak transition that are insensitive and sensitive, respectively, to atomic motion at 1 μK. We observe highly directional forward emission with a peak intensity that is enhanced, for the strong transition, by >10(3) compared with that in the transverse directio...
متن کاملCoherent Neutrino Propagation in a Dense Medium
Motivated by the effect of matter on neutrino oscillations (the MSW effect) we have studied the propagation of neutrinos in a dense medium. The dispersion relation for massive neutrinos in a medium is known to have a minimum at nonzero momentum p ∼ GF ρ/ √ 2. We have studied in detail the origin and consequences of this dispersion relation for both Dirac and Majorana neutrinos both in a toy mod...

متن کاملDetermination of functional collective motions in a protein at atomic resolution using coherent neutron scattering
Protein function often depends on global, collective internal motions. However, the simultaneous quantitative experimental determination of the forms, amplitudes, and time scales of these motions has remained elusive. We demonstrate that a complete description of these large-scale dynamic modes can be obtained using coherent neutron-scattering experiments on perdeuterated samples. With this app...
متن کاملSupplemental Material: Coherent scattering of near-resonant light by a Dense Microscopic Cold Atomic cloud
This Supplemental Material presents more details about the definition of the coherent transfer function S(ω) and the expressions of the laser field used in the modeling. It also derives the mean-field expression of the susceptibility for a multi-level alkali atom that we use in the Lorentz-Lorenz formula to calculate the field scattered by the cloud. Finally, we discuss the influence on the lin...
