Correlation between the boson peak frequency and transverse Ioffe-Regel limit in four-dimensional structural glasses
Licun Fu, Xinyu Chang, Lijin Wang
The emergence of excess vibrational modes over the Debye prediction, typically manifested as the well-known boson peak in the plot of vibrational density of states scaled by the De…

Structure-Preserving Implicit Runge-Kutta Methods for Stochastic Poisson Systems with Multiple Noises
Liying Zhang, Fenglin Xue, Lijin Wang
In this paper, we propose the diagonal implicit Runge-Kutta methods and transformed Runge-Kutta methods for stochastic Poisson systems with multiple noises. We prove that the first…
