Harmonic Solution of Higher-Dimensional Second Order Kuramoto Oscillator Network
IEEE AccessObtaining the solution of Kuramoto oscillator model is an effective way to understand the mechanism behind the dynamical behaviors it represents. However, it is not an easy work to get, even the approximation solution for the second order Kuramoto ...

Collective nature of phonon energies beyond harmonic oscillators
Computational Materials TodayPhonon quasi-particles have been monumental in microscopically understanding thermodynamics and transport properties in condensed matter for decades. Phonons have one-to-one correspondence with harmonic eigenstates and their energies are often described ...

The Mechanism of Visible‐Light Photochemical Rearrangements of Conjugated Amide Enolates
Chemistry – A European Journal, EarlyView.Visible light irradiation of extended enolates of N‐benzylamides leads to homolytic C─N Bond cleavage, generating a biradical. Computational and mechanistic studies suggest rapid radical recombination within a solvent cage to give either ring‐expanded or rearranged products. ABSTRACT Deprotonation of conjugated amides forms colored solutions of lithium
