Dmitry Budker

Atomic Experiment

Research Interests

Budker’s research interests are related to the study of violation of discrete symmetries – parity, time reversal invariance, and permutation symmetry for identical particles - using the methods of modern atomic physics. In particular, he has been involved in exploring the rare earth elements - samarium, dysprosium and ytterbium - where enhancement of P and P,T violating effects occurs due to close proximity of states with opposite nominal parity. More recently, he has also been involved in experimental search for temporal variation of fundamental “constants.” Such experiments involve many aspects and techniques of atomic physics, as well as of linear and nonlinear optics and spectroscopy. Some of the Budker group research involves experimental condensed-matter physics and nuclear magnetic resonance. Budker and his group are also studying applications of nonlinear optical phenomena in resonant vapors and in color centers in diamond to sensitive magnetometry. The group maintains a roughly 50-50 balance of fundamental-physics and applied projects.

Current Projects

The experiments currently being carried out include:
  • Experimental searches for P-violating effects in ytterbium Ultimately, this work may lead to a precision comparison of PNC effects on different isotopic and hyperfine transitions
  • Investigation of nonlinear optical rotation and its applications to sensitive magnetometry and fundamental physics
  • Investigation of spin-relaxation properties of atoms in cryogenic buffer gas environment
  • Experimental tests of Bose-Einstein quantum statistics for photons
  • Development of all-optical magnetic sensors for field and space applications
  • Nuclear magnetic resonance and magnetic-resonance imaging with atomic magnetometers.
  • Experimental search for a possible temporal variation of the fine-structure “constant” and measuring parity nonconservation using radio-frequency electric-dipole transitions in dysprosium
  • Investigation of fundamental properties of nitrogen-vacancy (NV) color centers in diamond and application of NV ensembles to sensitive magnetometry
  • Atomic physics of and remote magnetometry with mesospheric-sodium laser guide stars

Leefer, D. C. Hovde (Southwest Sciences, Inc.), A. Gordon (Israel), D. Bonaccini-Calia (ESO), R. Holzloehner (ESO), R. Folman (BGU, Israel), and many others. There are always several visitors and undergraduate students in the group. These experiments ideally suit the university environment since, in spite of their potential to produce results significant to our understanding of fundamental interactions, they are relatively small-scale; thus they can be carried out in a small research group and allow graduate and undergraduate students to actively participate in all aspects of the experiment - from planning and design and apparatus construction to data taking and analysis.
