The evolution of free wave packets
We discuss four general features of the force-free evolution of wave packets: 1 The spatial spread of a packet changes with time in a simple way. 2 For sufficiently short durations related to the spread in the momentum of the packet the probability distribution will move with uniform speed and little change in shape. 3 After a sufficiently long time related to the initial spatial spread the wav...
متن کاملTomographic reconstruction of designer free-electron wave packets.
We review the generation and tomographic reconstruction of designer electron wave packets, that is, electron wave packets with a tailored momentum distribution in the continuum. Generation is accomplished by means of multiphoton ionization of an atomic prototype using polarization-shaped femtosecond laser pulses. Both the electronic structure of the neutral and interference of matter wave packe...
متن کاملSelf-Interfering Wave Packets.
We study the propagation of noninteracting polariton wave packets. We show how two qualitatively different concepts of mass that arise from the peculiar polariton dispersion lead to a new type of particlelike object from noninteracting fields-much like self-accelerating beams-shaped by the Rabi coupling out of Gaussian initial states. A divergence and change of sign of the diffusive mass result...
متن کاملAutoionizing Rydberg wave packets.
In this paper we present some of the general features of autoionizing Rydberg wave packets. We assume the wave packets are generated by a short, perturbative laser pulse that excites the electronic wave function to a coherent distribution of final state energies in the autoionizing regime. We describe a possible experiment for generating and detecting these autoionizing wave packets. A physical...
متن کاملLévy–Schrödinger wave packets
We analyze the time–dependent solutions of the pseudo–differential Lévy–Schrödinger wave equation in the free (force-less) case, and we compare them with the associated Lévy processes. We first list the principal laws used to describe the time evolutions of both Lévy process densities and Lévy–Schrödinger wave packets. To have self–adjoint generators and unitary evolutions we will consider only...
