Keywords: | DRNTU::Science::Physics | Issue Date: | 2014 | Source: | Hu, Y.-X., Miniatura, C., Wilkowski, D., & Grémaud, B. (2014). U(3) artificial gauge fields for cold atoms. Physical Review A, 90(2), 023601-. | Series/Report no.: | Physical Review A | Abstract: | We propose to generate an artificial non-Abelian U(3) gauge field by using a two-tripod scheme, namely, two tripod configurations sharing a common ground-state level and driven by resonant one-photon transitions. Using an appropriate combination of four Laguerre-Gauss and two Hermite-Gauss laser beams, we are able to produce a U(3) monopole and a U(3) spin-orbit coupling for both alkali-metal and alkaline-earth-metal atoms. This two-tripod scheme could open the way to the study of interacting spinor condensates subjected to U(3) monopoles. | URI: | https://hdl.handle.net/10356/105050 http://hdl.handle.net/10220/20411 |
