Talk title:Test of Lorentz Symmetry with Trapped Atoms Speaker: Dr.Pruttivarasin Thaned Affiliation: RIKEN Quantum Metrology Laboratory Schedule:11:30―, 28th Aug (Thu)2014, Place:Room 435&437, Main building Language: English Abstract Lorentz symmetry, which requires the outcome of the experiment to be independent of its absolute orientation in space, is perhaps the most important cornerstone in modern physics, especially the Standard Model of particles. However, physics beyond the Standard Model might allow breaking of Lorentz symmetry at the experimental accessible energy scale. Therefore,　a search for violation of Lorentz symmetry directly probes physics beyond the Standard model. Precision testing of Lorentz symmetry has been undergoing a rapid progress recently due to development in laser technology　and atomic physics. In this talk, a novel experiment utilizing trapped calcium ions as a direct probe of Lorentz-violation is presented. Our result improves on the current most stringent bounds on Lorentz symmetry by up to　five times. The experimental scheme is readily applicable to many ion species, including highly-charged ions, hence opening up paths toward much improved test of Lorentz symmetry in the future. E3project seminar
