Revival structure of Stark wave packets

The Evolution and Revival Structure of Localized Quantum Wave Packets

Localized quantum wave packets can be produced in a variety of physical systems and are the subject of much current research in atomic, molecular, chemical, and condensed-matter physics. They are particularly well suited for studying the classical limit of a quantum-mechanical system. The motion of a localized quantum wave packet initially follows the corresponding classical motion. However, in...

Core Scattering of Stark Wave Packets

Tunable terahertz radiation from Stark wave packets.

We investigate the possibility that Stark wave packets can be used as a source of shaped terahertz radiation. Calculations for the sodium atom reveal that the frequency and intensity of the THz emission can be controlled over a broad range by varying the parameters of the excitation pulse.

Long-term evolution and revival structure of Rydberg wave packets for hydrogen and alkali-metal atoms.

This paper begins with an examination of the revival structure and long-term evolution of Rydberg wave packets for hydrogen. We show that after the initial cycle of collapse and fractional/full revivals, which occurs on the time scale t rev , a new sequence of revivals begins. We find that the structure of the new revivals is different from that of the fractional revivals. The new revivals are ...

Phase Structure of Strong-Field Tunneling Wave Packets from Molecules.

We study the phase structure of the tunneling wave packets from strong-field ionization of molecules and present a molecular quantum-trajectory Monte Carlo model to describe the laser-driven dynamics of photoelectron momentum distributions of molecules. Using our model, we reproduce and explain the alignment-dependent molecular frame photoelectron spectra of strong-field tunneling ionization of...
