... system that is resilient to noise in the magnetic field [28–30]. Preparation and detection of the dressed-state system is achieved using the method described in Ref. [30]. For preparation, a microwave π pulse transfers the population to j00 i after the ion has been optically pumped into the j0i stat ...

... What we have here is an example of a plane wave since at any instant both E and B are uniform over any plane perpendicular to the direction of propagation. In addition, the wave is transverse because both fields are perpendicular to the direction of propagation, which points in the direction of the ...

The energization processes are much more persistent than was expected in Refs. 1,2. We report the simulation ...

Time in physics



Time in physics is defined by its measurement: time is what a clock reads. In classical, non-relativistic physics it is a scalar quantity and, like length, mass, and charge, is usually described as a fundamental quantity. Time can be combined mathematically with other physical quantities to derive other concepts such as motion, kinetic energy and time-dependent fields. Timekeeping is a complex of technological and scientific issues, and part of the foundation of recordkeeping.
