A characteristic-spectral-mixed scheme for six-dimensional Wigner-Coulomb dynamics
Yunfeng Xiong, Yong Zhang, Sihong Shao
Numerical resolution for 6-D Wigner dynamics under the Coulomb potential faces with the combined challenges of high dimensionality, nonlocality, oscillation and singularity. In par…
Performance evaluations on the parallel CHAracteristic-Spectral-Mixed (CHASM) scheme
Yunfeng Xiong, Yong Zhang, Sihong Shao
Performance evaluations on the deterministic algorithms for 6-D problems are rarely found in literatures except some recent advances in the Vlasov and Boltzmann community [Dimarco…
On (non-)monotonicity and phase diagram of finitary random interlacement
Zhenhao Cai, Yunfeng Xiong, Yuan Zhang
In this paper, we study the evolution of a Finitary Random Interlacement (FRI) with respect to the expected length of each fiber. In contrast to the previously proved phase transit…
SPADE: Sequential-clustering Particle Annihilation via Discrepancy Estimation
Sihong Shao, Yunfeng Xiong
For an empirical signed measure , particle annihilation (PA) removes particles from both $\{x_i\}_{i=…
Branching random walk solutions to the Wigner equation
Sihong Shao, Yunfeng Xiong
The stochastic solutions to the Wigner equation, which explain the nonlocal oscillatory integral operator with an anti-symmetric kernel as {the generator of two branches of j…
