Multimode theory of electron hole transverse instability
Xiang Chen, I H Hutchinson
We present Vlasov-Poisson 3-D linear stability analysis of an initially planar electron hole structure, solving for the distribution function by integration along unperturbed orbit…
Role of electron-phonon coupling in excitonic insulator candidate Ta2NiSe5
Cheng Chen, Xiang Chen, Weichen Tang +15
Electron-hole bound pairs, or excitons, are common excitations in semiconductors. They can spontaneously form and ``condense'' into a new insulating ground state -- the so-called e…
Recent Progress in the Concurrent Atomistic-Continuum (CAC) Method and its Application in Phonon Transport
Xiang Chen, Weixuan Li, Adrian Diaz +3
This work presents recent the progress in the development of the Concurrent Atomistic-Continuum (CAC) method for coarse-grained space- and time-resolved atomistic simulations of ph…
Ballistic-diffusive Phonon Heat Transport across Grain Boundaries
Xiang Chen, Weixuan Li, Liming Xiong +5
The propagation of a heat pulse in a single crystal and across grain boundaries (GBs) is simulated using a concurrent atomistic-continuum method furnished with a coherent phonon pu…
Passing Waves from Atomistic to Continuum
Xiang Chen, Adrian Diaz, Liming Xiong +2
Progress in the development of coupled atomistic-continuum methods for simulations of critical dynamic material behavior has been hampered by a spurious wave reflection problem at…
