Order-disorder phase transitions for CH3NH3PbC13 are studied with density functional theory.Our calculations show that the disorder is manifested in two aspects
We theoretically and numerically study the propagation dynamics of a Gaussian beam modeled by the fractional Schr(o)dinger equation with different dynamic linea
Soliton molecules are firstly obtained by velocity resonance for the Gerdjikov–Ivanov equation, and n-order smooth positon solutions for the Gerdjikov–Ivanov
Particle tracking velocimetry (PTV) is one of the most commonly applied granular flow velocity measurement meth-ods. However, traditional PTV methods may have i
