Hace 3 días · There are several angular momentum operators: total angular momentum (usually denoted J ), orbital angular momentum (usually denoted L ), and spin angular momentum ( spin for short, usually denoted S ). The term angular momentum operator can (confusingly) refer to either the total or the orbital angular momentum.

Hace 2 días · The above equation is utilized to determine the values in the row j+1 across the grid, assuming that approximations at both rows j and j-1 are known: \[ u_{i,j+1} = \left( 2 - 2r^2 \right) u_{i,j} + r^2 \left( u_{i+1,j} + u_{i-1,j} \right) - u_{i,j-1} , \]

For a particle stuck on a sphere we can take an eigenbasis in terms of spherical harmonics, labeled with quantum numbers |j,m> with j a nonnegative integer and m ranging from -j to j and energy proportional to j(j+1). This is independent of the 2j+1 possible values of m, which is where the degeneracy comes from.
Hace 4 días · This equation is used to create the (j+1)-th row across the grid, assuming that approximations in the j-th row are known. Notice that this formula explicitly gives the value u i,j+1 in terms of u i-1,j, u i,j, and u i+1,j. The corresponding computational stencil is represented below.
Hace 4 días · Many researchers, scholars and engineers considered differential equations with one-parameter \varepsilon (0<\varepsilon \ll 1), multiplying the highest derivative of the equation. This type of equation is one-parameter singularly perturbed differential equation.
