Nonstationary distributions of wave intensities in Wave Turbulence
Yeontaek Choi, Young-Sam Kwon, Sanggyu Jo +1
We obtain a general solution for the probability density function of wave intensities in non-stationary Wave Turbulence. The solution is expressed in terms of the wave action spect…
Characteristics of neutrons and proton beams arising from two different Beam Nozzles
Yeon-Gyeong Choi, Yu-Seok Kim
Tandem or Van de Graaff accelerator with an energy of 3-MeV is typically used for PIXE analysis. In this study, the beam line design used in PIXE analysis was used to increase the…
Joint statistics of amplitudes and phases in Wave Turbulence
Yeontaek Choi, Yuri V. Lvov, Sergey Nazarenko
Random Phase Approximation (RPA) provides a very convenient tool to study the ensembles of weakly interacting waves, commonly called Wave Turbulence. In its traditional formulation…
Wave Turbulence
Yeontaek Choi, Yuri V. Lvov, Sergey Nazarenko
In this paper we review recent developments in the statistical theory of weakly nonlinear dispersive waves, the subject known as Wave Turbulence (WT). We revise WT theory using a g…
Probability densities and preservation of randomness in wave turbulence
Yeontaek Choi, Yuri V. Lvov, Sergey Nazarenko
Turbulence closure for the weakly nonlinear stochastic waves requires, besides weak nonlinearity, randomness in both the phases and the amplitudes of the Fourier modes. This random…
Anomalous probability of large amplitudes in wave turbulence
Yeontaek Choi, Yuri V. Lvov, Sergey Nazarenko +1
Time evolution equation for the Probability Distribution Function (PDF) is derived for system of weakly interacting waves. It is shown that a steady state for such system may corre…
