Lieb's soliton-like excitations in harmonic trap [PDF]
EPL (Europhysics Letters), 2013 We study the solitonic Lieb II branch of excitations in one-dimensional Bose-gas in homogeneous and trapped geometry. Using Bethe-ansatz Lieb's equations we calculate the "effective number of atoms" and the "effective mass" of the excitation.

Vibration responses characteristics of a Ginkgo biloba tree excited under harmonic excitation. [PDF]
PLoS One, 2021 The most effective method of the fruit harvesting is the mechanical harvest. The frequency spectrum of different testing positions on a Ginkgo biloba tree under the impact excitation was tested in the laboratory. The acceleration responses under the harmonic excitation were measured at the frequency of the peak and trough points in the frequency ...

Excitation with quantum light. I. Exciting a harmonic oscillator [PDF]
Physical Review A, 2016 We start a series of studies of the excitation of an optical target by quantum light. In this first part, we introduce the problematic and address the first case of interest, that of exciting the quantum harmonic oscillator, corresponding to, e.g., a single-mode passive cavity or a non-interacting bosonic field.

Harmonic chirp imaging method for ultrasound contrast agent [PDF]
, 2005 Coded excitation is currently used in medical ultrasound to increase signal-to-noise ratio (SNR) and penetration depth. We propose a chirp excitation method\ud for contrast agents using the second harmonic component of the response.

A Study on Second Harmonic Excitation in Electron Beam–Plasma Instability
Frontiers in Astronomy and Space Sciences, 2022 The electron beam–plasma interaction is a fundamental nonlinear plasma process that is frequently taking place in space and laboratory plasmas. Such an interaction is found to generate electromagnetic waves observed in space plasmas.
