Determining the wavelength of Langmuir wave packets at the Earth's bow shock
wavelength Langmuir wave packets Earth's bow shock
2011/8/5
Abstract: The propagation of Langmuir waves in plasmas is known to be sensitive to density fluctuations. Such fluctuations may lead to the coexistence of wave pairs that have almost opposite wave-numb...
Dynamic of rescattering-electron wave packets in strong and short-wavelength laser fields: Roles of Coulomb potential and excited states
scattering-electron wave packets in strong short-wavelength laser fields Coulomb potential excited states
2014/5/28
We investigate the high-order harmonic generation of atoms and molecules exposed in strong and shortwavelength (shorter than 800 nm) laser fields. Our simulations show that the electronic rescattering...

Engineering Biphoton Wave Packets Electromagnetically Induced Grating
2010/11/5
We propose to shape biphoton wave packets with an electromagnetically induced grating in a four-level double-$\Lambda$ cold atomic system. We show that the induced hybrid grating plays an essential ro...
Amplitude modulation and packet formation of Langmuir waves are commonly observed during a nonlinear interaction between electron beams and plasmas. In this paper, we briefly review the history of Lan...
Quantum models of classical mechanics: maximum entropy packets
Quantum classical mechanics maximum entropy packets
2010/4/7
In a previous paper, a project of constructing quantum models of classical properties has been started. The present paper concludes the project by turning to classical mechanics. The quantum states th...
An Instability of Packets of Short Gravity Waves in Waters of Finite Depth
Short Gravity Waves Finite Depth
2009/2/13
We consider the stability of a solitary wave packet of short gravity waves propagating in waters of moderate depth. It is shown that such wave packets are unstable to long transverse disturbances. The...
Evolution of Long Planetary Wave Packets in a Continuously Stratified Ocean
Long Planetary Wave Continuously Stratified Ocean
2008/7/2
Recent TOPEX/Poseidon observations show an enhanced (weakened) westward propagation of long planetary Rossby waves at extratropics (Tropics) and they usually propagate faster in the western basin than...

Spin dynamics wave packets evolving Dirac Hamiltonian atoms high Z
2010/10/15
The motion of circular WP for one electron in central Coulomb field with high Z is calculated. The WP is defined in terms of solutions of the Dirac equation in order to take into account all possible ...
Od-Interpretation of Kaolinite-Type Structures—I: Symmetry of Kaolinite Packets and their Stacking Possibilities

2012/2/14
The idealized symmetry of kaolinite-type minerals (1:1 phyllosilicates) is analysed in detail. They can be considered as OD-structures consisting of three kinds of OD-layers. Each of them, taken separ...
