I'm expanding a function in spherical harmonics. I want to conserve axisymmetry of the function. what harmonics would respect that? Should I only include m=0 terms?
Spherical harmonics are a set of mathematical functions used to represent the angular dependence of a function on a sphere. They are commonly used in physics and engineering to describe the behavior of physical systems that exhibit spherical symmetry.
Axisymmetry refers to the property of a system where it is symmetric about an axis. In the context of spherical harmonics, axisymmetry means that the function being described has the same value at every point along a fixed axis, regardless of rotation about that axis.
Spherical harmonics are used in a variety of scientific fields, including physics, chemistry, and geophysics. They are commonly used to solve differential equations, describe the behavior of electromagnetic fields, and model the shape of molecules.
Yes, spherical harmonics can be used to describe non-spherical systems by expanding the function in terms of spherical harmonics and then truncating the series at a certain order. This allows for an approximation of the non-spherical system using spherical harmonics.
Yes, spherical harmonics axisymmetry has many real-world applications. For example, it is used in satellite imaging to analyze the Earth's gravitational field, in nuclear magnetic resonance to determine molecular structure, and in computer graphics to create realistic lighting effects.
