The time-dependent Schrödinger equation described above predicts that wave functions can form standing waves, called stationary states. These states are particularly important as their individual study later simplifies the task of solving the time-dependent Schrödinger equation for any state. Stationary states can also be described by a ...
Therefore, once the Hamiltonian is known, the time dynamics are in principle known. All that remains is to plug the Hamiltonian into the Schrödinger equation and solve for the system state as a function of time. [1] [2] Often, however, the Schrödinger equation is difficult to solve (even with a computer). Therefore, physicists have developed ...
The time-independent Schrödinger equation states that | = | ; substituting for | in terms of the basis states from above, and multiplying both sides by | or | produces a system of two linear equations that can be written in matrix form, () = (), or = which is a 2×2 matrix eigenvalues and eigenvectors problem. As mentioned above, this equation ...

which is an eigenvalue equation. Very often, only numerical solutions to the Schrödinger equation can be found for a given physical system and its associated potential energy. However, there exists a subset of physical systems for which the form of the eigenfunctions and their associated energies, or eigenvalues, can be found.
The time-dependent Schrödinger equation for the system is ... One must solve the time-independent Schrödinger equation to find the energy levels and corresponding ...
In both diffusion Monte Carlo and reptation Monte Carlo, the method first aims to solve the time-dependent Schrödinger equation in the imaginary time direction. When you propagate the Schrödinger equation in time, you get the dynamics of the system under study.
Multi-configuration time-dependent Hartree (MCTDH) is a general algorithm to solve the time-dependent Schrödinger equation for multidimensional dynamical systems consisting of distinguishable particles.
