WebJul 10, 2024 · Gaussian by default uses a dynamic trust radius for optimizations to a minimum (you also ensured this by including the trustupdate option). When you specify a maxstep this is only guaranteed to be the initial trust radius. In fact, the second step will ensure the trust radius is at least 0.05. WebA full reflection of geometry changes during optimization can be achieved using either the opt=nomicro keyword or the definition of a particular coordinate system with the opt=Z …

The azimuthal quantum number (OAM) of light has received a lot of attention over the past two decades. OAM was first derived from the Laguerre-Gaussian (LG) beams and defined by the number of 2π phase shifts across the azimuthal direction of its wavefront [1].This parameter has been driven by interest in several …
