A higher-order accurate operator splitting spectral method for the Wigner-Poisson system
Zhenzhu Chen, Haiyan Jiang, Sihong Shao
An accurate description of 2-D quantum transport in a double-gate metal oxide semiconductor filed effect transistor (dgMOSFET) requires a high-resolution solver to a coupled system…

Numerical methods for the Wigner equation with unbounded potential
Zhenzhu Chen, Yunfeng Xiong, Sihong Shao
Unbounded potentials are always utilized to strictly confine quantum dynamics and generate bound or stationary states due to the existence of quantum tunneling. However, the existe…

An advective-spectral-mixed method for time-dependent many-body Wigner simulations
Yunfeng Xiong, Zhenzhu Chen, Sihong Shao
As a phase space language for quantum mechanics, the Wigner function approach bears a close analogy to classical mechanics and has been drawing growing attention, especially in sim…
