We developed a hybrid approach to quantitatively characterize phonon quasiparticles by combing first-principles molecular dynamics and lattice dynamics [1].
The dynamic fragmentation of shock-melted metal is a topic of increasing interest in shock physics.However,high-quality experimental studies of the phenomenon are limited,experimental data that are es
With molecular dynamics simulations,we investigate the effects of porosity and specific surface area on shock response of open-cell nanoporous Cu foams,including compression,shock velocity-particle ve
The recently discovered orthorhombic allotrope of silicon,Si24,is Earth abundant,environmentally stable,and has a quasi-direct bandgap near 1.3eV; therefore an exciting prospective material for the fu
We measure in real time absorption spectra of single crystal MgO oriented along [100] under shock loading.The absorption peaks at 2.59 eV and 2.35 eV are caused by cation vacancy(V or color center).
Since the discovery of single-bonded cubic nitrogen polymorph(cg-N) in 2004 many experimental and theoretical studies were dedicated to search of nitrides featuring similar polymeric nitrogen units [1
