Resolving the spurious-state problem in Dirac equation by using the staggered-grid method
Lingfeng Li, Hong Shen, Jinniu Hu +1
Discretizing the Dirac equation on a uniform grid with the central difference formula often generates spurious states. We propose a staggered-grid scheme in the framework of the fi…

One-dimension Periodic Potentials in Schrödinger Equation Solved by the Finite Difference Method
Lingfeng Li, Jinniu Hu, Ying Zhang
The one-dimensional Kronig-Penney potential in the Schrödinger equation, a standard periodic potential in quantum mechanics textbooks known for generating band structures, is solv…
