Special Issue Information

Dear Colleagues,

It is well-known that laser techniques provide unique means of manipulating small particles. The interaction between light and particles is the main focus of this subject. A prime example of these techniques is the cooling of atomic vapor to extremely low temperatures to form new states of matter, i.e., BEC (Bose–Einstein condensate) and DFG (degenerate Fermi gas), which shed new light on a range of popular topics.

Nowadays, rapid developments in the field of AMO (atomic, molecular, and optical) physics have revolutionized research in many areas, including fundamental physics, precision spectroscopy and measurement, quantum metrology, astronomy and astrophysics, geodesy and hydrology, quantum simulation, and information and computation. Moreover, recent advances also provide sensitive and flexible scientific tools, e.g., atom lithography, optical tweezers, atomic magnetometers, atomic gyroscopes, atomic interferometers, atomic gravimeters, atomic clocks, etc.

This Special Issue focuses on the laser manipulation of neutral atoms, aiming to collect the latest progress in fundamental research and related applications in this area. You are invited to submit your original research papers and review papers to this Special Issue. Technical topics include but are not limited to the following:

  • Laser cooling and trapping;
  • Quantum gases;
  • Laser-based precision spectroscopy;
  • Optical tweezers;
  • Atoms in an optical cavity;
  • Atoms in an optical lattice;
  • Atomic frequency standards and clocks;
  • Atomic magnetometer and gyroscope;
  • Atomic interferometer;
  • Quantum simulation and computation with atoms;
  • Spin squeezing and quantum entanglement with atoms;
  • Search for the new physics of atoms.

The high-precision determination of microwave radiation parameters may be based on measurements of the spectral characteristics of radiation transitions between the Rydberg states of atoms. Frequencies and matrix elements are calculated for dipole transitions from even-parity nS1/2 and nD5/2 to odd-parity nP3/2 and nF7/2 (where n = n, n ± 1, n ± 2) for the Rydberg states of alkali-metal atoms. The matrix elements determine the splitting of Rydberg-state energy levels in the field of a resonance microwave (μw) radiation, which results in the splitting of the resonance in electromagnetic induced transparency (EIT). Numerical computations based on the single-electron quantum defect method (QDM) and the Fues’ model potential (FMP) approach with the use of the most reliable data of the current literature on quantum defect values were performed for the 2S, 2P, 2D and 2F series of the Rydberg states of Li, Na, K, Rb and Cs atoms. The calculated data were approximated by quadratic polynomials of the principal quantum number. The polynomial coefficients were determined with the use of a standard curve-fitting interpolation polynomial procedure for numerically presented functions. The approximation equations may be used for the accurate evaluation of the frequencies and matrix elements of μw transitions in wide ranges of the Rydberg-state quantum numbers n >> 1. Full article
