The vertical motion of atoms as a function of time (black) is manipulated by the effects of fast light pulses (blue). Figure reproduced from arxiv:1312.6449 https://images.squarespace-cdn.com/content/v1/55b1c452e4b02d875c761dc9/1441119252325-XL6WYQO8BGO27RPARN4A/image-asset.png Atom interferometry Introduction Figure 2: In a stimulated Raman transition, the atom is illuminated with counter-propagating laser beams. The atom absorbs a photon from one beam and emits a photon into a beam moving the opposite direction. The result is a net kick of 2 photon momenta. In this type of transition, the atom changes both its kinetic energy and its internal state. https://images.squarespace-cdn.com/content/v1/55b1c452e4b02d875c761dc9/1441119841021-FM7UC1J68D9IL42LVK74/Bragg.png Atom interferometry Introduction Figure 3: In a Bragg transition, two counter-propagating beams are detuned so that transferring a specific number of photon momenta is resonant. In this diagram, the atom absorbs the momentum of 8 photons, though a different detuning would transfer a different number of photon momenta. The atom remains in the ground electronic state, but gains kinetic energy. Our group helped invent and characterize this method for atom interferometry and remains a speciality of two of our interferometers. http://matterswaves.com/projects-overview daily 0.75 2020-09-20 https://images.squarespace-cdn.com/content/v1/55b1c452e4b02d875c761dc9/1441209509627-BO1AY86PJ0CI652EXFVD/_MG_8530.JPG Projects https://images.squarespace-cdn.com/content/v1/55b1c452e4b02d875c761dc9/1441340216238-A2FCEYH1F7XPHU9YRU3Y/image-asset.jpeg Projects Cesium cavity interferometer https://images.squarespace-cdn.com/content/v1/55b1c452e4b02d875c761dc9/1441231844362-YXB2SMZDF3IV2HS5TOGN/image-asset.jpeg Projects Compact atom interferometer https://images.squarespace-cdn.com/content/v1/55b1c452e4b02d875c761dc9/1441340305174-GWBB0A25L1KO3AC46TIK/_MG_8552+copia.jpg Projects Cesium atomic fountain https://images.squarespace-cdn.com/content/v1/55b1c452e4b02d875c761dc9/1441340474657-SVJ9OGK8TYNELCP74FJI/image-asset.jpeg Projects Lithium interferometer https://images.squarespace-cdn.com/content/v1/55b1c452e4b02d875c761dc9/1498543930262-9CS77PLQ5XR3IH16GZIU/image-asset.jpeg Projects Phase contrast electron microscopy http://matterswaves.com/publications/theses daily 0.75 2024-03-20 http://matterswaves.com/electronics-for-pros daily 0.75 2025-01-08 http://matterswaves.com/lab-access daily 0.75 2021-01-21 http://matterswaves.com/optical-recording-of-biological-signals daily 0.75 2026-02-03 http://matterswaves.com/electron-microscopy-introduction daily 0.75 2022-05-26 https://images.squarespace-cdn.com/content/v1/55b1c452e4b02d875c761dc9/1689d480-fcfe-4cfc-9343-75ba85f75b05/image_2022-04-06_123440364.png Electron Microscopy Introduction - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://images.squarespace-cdn.com/content/v1/55b1c452e4b02d875c761dc9/ef46912c-43ae-437d-8d40-d30f8d00f7f2/image_2022-04-06_123456988.png Electron Microscopy Introduction - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://images.squarespace-cdn.com/content/v1/55b1c452e4b02d875c761dc9/4135e978-421c-47ad-a848-1267abf7907d/image_2022-04-06_123510432.png Electron Microscopy Introduction - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://images.squarespace-cdn.com/content/v1/55b1c452e4b02d875c761dc9/90981fac-6d62-49ef-8b47-41b83485a735/image_2022-04-06_123525331.png Electron Microscopy Introduction - Make it stand out Whatever it is, the way you tell your story online can make all the difference. http://matterswaves.com/optical-trap-for-molecules daily 0.75 2026-03-02 https://images.squarespace-cdn.com/content/v1/55b1c452e4b02d875c761dc9/addd96c8-d948-4a4f-aec6-2ef368ded3fa/opposing_beams_schematic_snip.PNG Buffer-Gas-Loaded, Deep Optical Trapping of Molecules - Make it stand out Schematic design of the trap.
