SYSTEMSWe construct two Darboux transformations of arbitrary order for the Dirac equation in cylindrical coordinates. The systems we consider include a vector potential and a position-dependent mass that depend on the radial coordinate only. A reality condition for second-order Darboux transformations is...

This MATLAB function calculates the position vector in the Earth-centered inertial (ECI) coordinate system for a given position vector in the Earth-centered Earth-fixed (ECEF) coordinate system at a specific Coordinated Universal Time (UTC).

(Equivalently, such group is determined by the choice of a timelike vector in spacetime.) In Poincaré-invariant field theories we can choose inertial coordinates (t, x1, x2, x3) such that our chosen ? acts via (t, x1, x2, x3)→ (t + s, x1, x2, x3). In such coordinates, ...
Find the x and y components of the vector given in the standard position. t=800 in at 310∘. Components of a Vector: A vector is a physical quantity that is denoted by magnitude and direction. The length of a vector is proportional to its magnitude. We...
Special interest among its applications is the two-dimensional Fourier transform of a function, f(r)=f(r,ϕ), in polar coordinates. If we write the function f(r, ϕ) as a product and angular parts f(r,ϕ)=f(r)eimϕ, then its Fourier transform is given as [1]f˜(p)=12...

In the position shown in Fig. 1, the vector potential is strong or high in the interpolar region, and low elsewhere : dark = strong, light = weak. Indeed it appears to be strongest in the air regions (including the interior of the slot), although it is not quite zero in the magn...
