Physically, characteristic lines or tra jectories of Hamiltonian dynamical system (1.9) are interpreted as rays or beams in wave propagation process.
On the concept of normal shift in non-metric geometry
All these are accurately modeled as elastic manifolds in the presence of randomness. A second class of disordered elastic systems is given by periodic structures such as charge density waves , vortex ﬂux lines in type-II superconductors and Wigner crystals .
Universal Statistics of the Critical Depinning Force of Elastic Systems in Random Media
Sazhin [64, 65] ﬁrst suggested detection of gravitational waves from a binary system using timing observations of a pulsar, the line of sight to which passes near the binary.
General Relativistic Theory of Light Propagation in the Field of Radiative Gravitational Multipoles
Figure 2: (Color online) Evolution of ReG(k, 0) with increasing interaction V for t′ /t = 0.4 and for half- ﬁlled system of N = 26 sites with allowed wave vectors (points) and indications of kF = π/2 (dashed line) and kL (full line).
Breakdown of the Luttinger sum rule within the Mott-Hubbard insulator
There were two lines of development: Some authors looked for signals of classical chaos in the time–evolution of wave packets, others focused attention on the ﬂuctuation properties of eigenvalues and eigenfunctions of closed systems (which possess a discrete spectrum).
Random Matrices and Chaos in Nuclear Physics
Under these conditions, slow modes propagate along magnetic ﬁeld lines and are unable to transfer energy from the prominence into the corona and so wave leakage in the system studied by Schutgens and T ´oth (1999) is only possible by fast waves.
Prominence seismology using small amplitude oscillations
FIG. 2: Scheme of the Mott-superﬂuid transition in the homogeneous system for average occupation number hni = 1: increasing the lattice depth V (black line) the atoms superﬂuid wave functions (upper) localize in the wells (lower).
Optimal control technique for Many Body Quantum Systems dynamics
The predicted modiﬁcation of XPS lineshapes should be measurable in systems undergoing charge density wave or metal insulator transitions where gap scales are large compared with core hole lifetimes; the associated shift in lines may be measurable for superconducting systems with much smaller gaps.
Orthogonality Catastrophe Revisited
Then one should start the system in a superposition of states on the left side of the line graph with phases deﬁned so that if the NAND-tree were not attached, the “wave packet” would move from left to right along the line.
Fig.5 and 6 shows the h+ polarization of the gravitational wave calculated for a face-on orientation of the system relative to the line of sight, and the corresponding angle averaged metric strains hh2 i for cases of Taam’s and Weaver et al’s red giants.
Gravitational Radiation during Thorne-Zytkow object formation
For parameters U , W belonging to the area above the plotted lines (mostly in the 1st quarter of coordinate system) two-electron bound states, and what follows s-wave superconductivity in two dimensions, can not exist.
Bound states in the phase diagram of the extended Hubbard model
In the whole line case, for the Boussinesq case and the KGZ system (and as a direct application of the main results), we compute explicitly the set of speeds which give rise to linearly stable traveling waves (and for all powers of p in the case of Boussinesq).
Linear stability analysis for traveling waves of second order in time PDE's
Form factors F1,2,3 can be expanded into partial waves to show explicit dependence on θK , where θK is the angle between the kaon three-momentum in the kaon rest frame and the line of ﬂight of the kaon-pion system in the D rest frame.
