Note on the P-basis mentioned by Shankar :
In solving the one-dimensional Schrödinger equation, the
potential V(x) is usually a more complicated function of x
than the kinetic energy is of p. The position and momentum obey the
commutation relation , and the standard approach is to write
However, we could
equally write
the commutation relations are satisfied, and
writing the Hamiltonian in terms of
leads to a differential equation whose solution is the p-space
representation (the Fourier transform) of the usual y(x). This is
occasionally the best strategy—in particular, for a particle in a linear
potential.
