The Simple Harmonic Oscillator [PDF]
, 2017 AbstractThis chapter will introduce a system that is fundamental to our understanding of more physical phenomena than any other. Although the “simple” harmonic oscillator seems to be only the combination of the most mundane components, the formalism developed to explain the behavior of a mass, spring, and damper is used to describe systems that range ...

Tunable Polariton Rabi Oscillation in Phase‐Changing Perovskite Microcavities
Advanced Science, EarlyView.This work demonstrated the tunable Rabi oscillation of exciton‐polaritons in MAPbBr3 perovskites due to the emergence of ferroelectricity during the crystallographic phase transition. Both the Rabi oscillation and exciton oscillator strength exhibit an unusual temperature dependence that is related to the emergence of ferroelectricity in the tetragonal

InfoMat, Volume 4, Issue 12, December 2022., 2022 Metamaterials provide unique opportunities for exciting sensing functionalities and applications, while suffering from severe performance limitations due to noise interference and design constraints. By subtly controlling and integrating different Fano‐resonant phases, a dual‐phase strategy is developed to breakthrough these limitations.

A Key Fragment in Carbon Schwarzite Unit Cells and Its Triple [6]Helicene Precursor
Angewandte Chemie, EarlyView.Adjusting the conditions of Scholl reactions has enabled the selective synthesis of polycyclic arenes with two related π‐skeletons. One π‐skeleton is a key fragment of theoretical carbon schwarzites, while the other is a triple [6]helicene, which exhibits unique supramolecular structures in the clathrate with chloroform and an absorption dissymmetry ...

The harmonic balance method for Yao–Cheng oscillator
Journal of Low Frequency Noise, Vibration and Active Control, 2019 Recently Yao and Cheng suggested a nonlinear oscillator with a damping, and an analytical solution was obtained by the homotopy perturbation method. This paper shows that the oscillator can also be effectively solved by the harmonic balance method.
