Abstract Variations in Earth's orbit and axial tilt induce climatic changes which are recorded in sedimentary deposits. The frequencies of these cyclical variations are integer combinations of the main secular frequencies of the solar system. Analyzing these cycles in sedimentary records can help establish an astronomical time scale for the geological ...

N-Photon wave packets interacting with an arbitrary quantum system
We present a theoretical framework that describes a wave packet of light prepared in a state of definite photon number interacting with an arbitrary quantum system (e.g. a quantum harmonic oscillator or a multi-level atom).
