I was wondering what is known about the solution of the Schrödinger equation $$i h \frac{\partial}{\partial t} Ψ(x, t) =- \frac{h^2}{2m}\Delta Ψ(x,t)+V(x)Ψ(x, t)$$ for $t ∈ \mathbb{R}$. What sort of conditions are put on the potential $V$ to guarantee a solution and what space does a solution ... | http://math.stackexchange.com/questions/215787/solution-of-schr%c3%b6dingers-equation | <urn:uuid:597a6b7b-19e9-4a66-98e5-b44bf1b8feed> | en | 0.882232 | 0.458007 |

I want to solve the time-dependent Schroedinger equation:
$$ i\partial_t \psi(t) = H(t)\psi(t) $$
for matrix, time-dependent $H(t)$ and vector $\psi$.
What is an efficient way of doing this so that it efficiently scales to high-dimensional spaces?

The Schrödinger equation in its variants for many particle systems gives the full time evolution of the system. Likewise, the Boltzmann equation is often the starting point in classical gas dynamics.
What is the relationship, i.e. the classical limit, which connects these two first order in time equations o... | http://physics.stackexchange.com/questions/20950/what-is-the-relationship-between-schr%c3%b6dinger-equation-and-boltzmann-equation | <urn:uuid:aa74c304-eda6-4dd2-81b2-5ee4b23562dd> | en | 0.924236 | 0.830787 |
