Classifications of surface waves in magneto-electro-elastic materials

open access: yesResults in Physics, 2023
The present study investigates the classifications of surface waves in magneto-electro-elastic materials. First, the standard eigenrelation, relating to the generalized displacement and the generalized tractions, is derived from the governing equations ...

Spectral pruning of fully connected layers

open access: yesScientific Reports, 2022
Training of neural networks can be reformulated in spectral space, by allowing eigenvalues and eigenvectors of the network to act as target of the optimization instead of the individual weights.

The Rabi Oscillation in Subdynamic System for Quantum Computing

open access: yesAdvances in Mathematical Physics, 2015
A quantum computation for the Rabi oscillation based on quantum dots in the subdynamic system is presented. The working states of the original Rabi oscillation are transformed to the eigenvectors of subdynamic system. Then the dissipation and decoherence

Algebraic Bethe ansatz for the Temperley–Lieb spin-1 chain

open access: yesNuclear Physics B, 2016
We use the algebraic Bethe ansatz to obtain the eigenvalues and eigenvectors of the spin-1 Temperley–Lieb open quantum chain with “free” boundary conditions.
