Precision timekeeping with atomic clocks: evolution and future directions

|
By Anjali Bisht, Poonam Arora, Venu Gopal Achanta
| Nature Verified
Abstract Accurate timekeeping is foundational to modern society, supporting critical technologies such as global navigation satellite systems (GNSS), high-frequency financial trading, synchronization of communication networks, and the realization of SI base units. Here we review the evolution of timekeeping, with a particular emphasis on atomic clocks and their applications.

| MDPI
Abstract : Light propagation through magnetic media with ellipsoidal inclusions much smaller than the light wavelength was investigated theoretically. It is assumed that the ellipsoidal inclusions have the same orientation but are randomly distributed inside the magnetic medium by the Gaussian law. The theoretical model is based on the multiple-scattering theory in the ladder approximation.
