Laser-induced valence electron excitation in acetylene

open access: yesFrontiers in Physics, 2022
Strong-field induced valence electron excitation is a common process in strong field interaction with atoms and molecules. In the case of polyatomic molecules, the effects of ionization from low-lying molecular orbitals and nuclear dynamics during the ...

Order, Criticality, and Excitations in the Extended Falicov-Kimball Model [PDF]

open access: yesPhysical Review Letters, 2014
Using exact numerical techniques we investigate the nature of excitonic (electron-hole) bound states and the development of exciton coherence in the one-dimensional half-filled extended Falicov-Kimball model. The ground-state phase diagram of the model exhibits, besides band insulator and staggered orbital ordered phases, an excitonic insulator (EI ...

Critical Steady-State Response of Single-Degree-of-Freedom Bilinear Hysteretic System under Multi Impulse as Substitute of Long-Duration Ground Motion

open access: yesFrontiers in Built Environment, 2017
A set of multiple impulses is introduced as a substitute of many-cycle harmonic waves which represent the long-duration earthquake ground motion. A closed-form expression is derived of the elastic–plastic response of a single-degree-of-freedom structure ...

Optimal Viscous Damper Placement for Elastic-Plastic MDOF Structures Under Critical Double Impulse

open access: yesFrontiers in Built Environment, 2019
A new method for optimal viscous damper placement is proposed for elastic-plastic multi-degree-of-freedom (MDOF) structures subjected to the critical double impulse as a representative of near-fault ground motions.

Compromised Vibration Isolator of Electric Power Generator Considering Self-Excitation and Basement Input

open access: yesInventions, 2023
A previous study proposed an optimal vibration isolator for self-excitation, but the solution results showed a critical drawback for the basement input.

Critical Earthquake Response of 2DOF Elastic-Perfectly Plastic Model Under Multiple Impulse as Substitute for Long-Duration Earthquake Ground Motions

open access: yesFrontiers in Built Environment, 2019
An equi-spaced consecutive impulse input is treated as a simplified representative for a long-duration earthquake ground motion. The key property of such input can be captured approximately by using harmonic waves.
