2013-05-25 | Soliton interaction mediated by cascaded four wave mixing with dispersive waves | We demonstrate that trapping of dispersive waves between two optical solitons
takes place when resonant scattering of the waves on the solitons leads to
nearly perfect reflections. The momentum transfer from the radiation to
solitons results in their mutual attraction and a subsequent collision. The
spectrum of the tra... | 1305.5909v1 |
2013-11-23 | Enhanced propagation of photon density waves in random amplifying media | We demonstrate enhanced wave-like character of diffuse photon density waves
(DPDW) in an amplifying random medium. The amplifying nature makes it
contingent to choose the wave solution that grows inside the amplifying medium,
and has a propagation vector pointing opposite to the growth direction. This
results in negati... | 1311.5985v1 |

internal gravity waves has become a central subject of research in
oceanography. The time evolution of the spectral energy of internal waves in
the ocean can be described by a near-resonance wave turbulence equation, of
quantum Boltzmann type. In ... | 1709.08266v3 |
2017-11-26 | Response solutions for wave equations with variable wave speed and periodic forcing | We consider a model of nonlinear wave equations with periodically varying
wave speed and periodic external forcing. By imposing non-resonance conditions
on the frequency, we establish the existence of the response solutions (i.e.,
periodic solutions with the same frequency as the forcing) for such a model in
a Cantor s... | 1711.09437v2 |
2017-05-05 | Dykes for filtering ocean waves using c-shaped vertical cylinders | The present study investigates a way to design dykes which can filter the

structure that can attenuate waves associated with storm swell, without
affecting coastline in other conditions. Our approach is based on low frequency
resonances in met... | 1705.02132v1 |

including the ... | 1406.6042v2 |
2017-06-25 | Sub-wavelength focusing of acoustic waves in bubbly media | The purpose of this paper is to investigate acoustic wave scattering by a
large number of bubbles in a liquid at frequencies near the Minnaert resonance

in time traveling waves for the 2d pure gravity water waves system in infinite
depth. We provide the first existence result of quasi-periodic water waves
solutions bifurcating from a completely resonant elliptic fixed point. The
proof is based ... | 2011.12794v1 |
2021-04-13 | Magnetless Reflective Gyrotropic Spatial Isolator Metasurface | We present the concept of a magnetless Reflective Gyrotropic Spatial Isolator
(RGSI) metasurface. This is a birefringent metasurface that reflects vertically
polarized incident waves into a horizontally polarized waves, and absorbs
horizontally polarized incident waves, hence providing isolation between the
two orthogo... | 2104.09300v1 |
2021-10-22 | Wide elastic wave bandgap metamaterial with single phase constituent | Accomplishing a wide elastic wave bandgap with single phase constituent is of

2008-06-09 | On Electromagnetic Wave Interaction with Dense Resonant Atom Medium | The excitation of atomic levels due to interaction with electromagnetic waves
became of interest in accelerator physics in relation to high efficiency charge
exchange injection into rings for high beam power applications. Usually, the
beam density is so small that its influence on the wave is completely
neglected. Here... | 0806.1526v1 |
2016-11-14 | Shortcut to adiabatic control of soliton matter waves by tunable interaction | We propose a method for shortcut to adiabatic control of soliton matter waves
in harmonic traps. The tunable interaction controlled by Feshbach resonance is
inversely designed to achieve fast compression of soliton matter waves but
within a short time, as compared to the conventional adiabatic compression.
These result... | 1611.04371v1 |
2020-10-29 | Mode Conversion and Period Doubling at Plasma-$β$ Unity in an Alfvén-Wave Experiment with Liquid Rubidium | We report Alfv\'en-wave experiments with liquid rubidium at the Dresden High
Magnetic Field Laboratory (HLD). Reaching up to 63 T, the pulsed magnetic field
exceeds the critical value of 54 T at which the Alfv\'en speed becomes equal to
the sound speed (plasma-$\beta$ unity). At this threshold we observe a period

find that a solitary wave can bounce back and forth remaining close to its
initial position when... | 2209.03085v1 |
2023-07-24 | On the transverse stability of smooth solitary waves in a two-dimensional Camassa-Holm equation | We consider the propagation of smooth solitary waves in a two-dimensional
generalization of the Camassa--Holm equation. We show that transverse
perturbations to one-dimensional solitary waves behave similarly to the KP-II
theory. This conclusion follows from our two main results: (i) the double
eigenvalue of the linear... | 2307.12821v1 |

1915+105, GRO J1655-40, and XTE J1550-564 have been carried out based on

2005-02-01 | Can Frustration Preserve a Quasi-Two-Dimensional Spin Fluid? | Using spin-wave theory, we show that geometric frustration fails to preserve
a two-dimensional spin fluid. Even though frustration can remove the interlayer
coupling in the ground-state of a classical anti-ferromagnet, spin layers
innevitably develop a quantum-mechanical coupling via the mechanism of ``order
from disor... | 0502003v2 |
2005-11-11 | The time dependence of muon spin relaxation spectra and spin correlation functions | The existing theory of the microscopic interpretation of the dynamical
contribution to zero-field muon depolarization spectra in a longitudinal
geometry is developed. The predicted relaxation of the muon depolarization is
calculated from two forms of the spin correlation function. First, when the
spin correlation funct... | 0511288v1 |

current can be generated simply by the diffraction through a single slit in the

accreting systems. Taking both the accretion induced field decay and spin-up
into consideration, we calculate their spin-period evolutions influenced by the
initial magnetic-field strengths, initial spin-periods and accretion rates,
respectively. T... | 1011.5013v1 |
2014-12-18 | Spinor Bose gas in an elongated trap | We examine a spinor Bose gas confined by an elongated trap. Since a
spin-independent energy is much higher than a spin-dependent energy in alkali
species, the system exhibits different properties by changing a radial
confinement. We show that if a spin-dependent coupling is positive, a
spin-liquid condensate, which bre... | 1412.6066v2 |

$S_c$ is the spin... | 1502.04107v2 |
2015-05-06 | Reexamination of the Elliott-Yafet spin-relaxation mechanism | We analyze spin-dependent carrier dynamics due to incoherent electron-phonon
scattering, which is commonly referred to as Elliott-Yafet (EY) spin-relaxation
mechanism. For this mechanism one usually distinguishes two contributions: (1)
from the electrostatic interaction together with spin-mixing in the wave
functions, ... | 1505.01432v2 |

Pt/Y$_{3}$Fe$_{5}$O$_{12}$) and the normal metal/ferromagnetic metal/oxide
trilayer (such as Pt/Co/AlO$_{x}$) where spin injection and ejection are
achieved by the spin Hall effect in the normal metal, we propose a minimal
model based on quantum tunneling of ... | 1507.06447v2 |

insulating substrates is revealed, and quantitatively examined by means of
density functional calculations combined with a kinetic equation. The

films, is found to pro... | 1604.01559v1 |
2016-04-21 | Electron spin filter and polarizer in a standing light wave | We demonstrate the theoretical feasibility of spin-dependent diffraction and
spin-polarization of an electron in two counter-propagating, circularly
polarized laser beams. The spin-dynamics appears in a two-photon process of the
