About the book
Hyperfine structures are an important aspect of physics which has profound implications for atomic clocks, precision tests of fundamental theories, isotope separation, and quantum computing using cold atoms. Sophisticated and ever-improving experimental techniques together with evolving theoretical methods have been pushing the boundaries of our knowledge and understanding of hyperfine structures and spectroscopy. Methods of inteferometric spectroscopy and continued development in experimental precision have driven this vital arm of physics to pose new challenges and ask profound questions. The effects of electric quadrupole moments, nuclear dipole moments, and beyond have become accessible through these methods, knocking the doors for testing the foundations of physics. These have been complimented and sometimes led on by theoretical methods of ever increasing sophistication in the form of multi-configuration methods for both non-relativistic and relativistic scenarios in the form of Hartee-Fock and Dirac-Fock approaches, respectively. In this book we present scholarly accounts of all these aspects and take the reader through to applications of hyperfine structure studies and spectroscopy, among which the most known would be atomic clocks, isotope separation, and cold atom systems for quantum computing, to name a few. While we continue to push the envelope of our understanding of hyperfine structures, physics is enriched by new challenges and opportunities herein.
