In 1905, Einstein established relativity under the condition of denying the absolute space-time valid in Newtonian mechanics. In those days, the quantum theory was also established by accepting De ...

This paper presents the critical-point-based stability analyses of finite-difference time-domain (FDTD) methods for Schrödinger equation incorporating vector and scalar potentials. Most previous FDTD ...
