Driven Problems in Quantum and Classical Mechanics with Floquet
... Driven systems appear in various forms in both classical mechanics and quantum mechanics. Some simple forms allow for analytical solutions, which can then be analyzed and studied in detail. For those that do not, there are tools to make qualitative statements about their general behaviour. In this p ...

CS286.2 Lectures 5-6: Introduction to Hamiltonian Complexity, QMA
... The first result along these lines came from Kitaev, who showed that 5 − LH is QMA-complete. We shall show a slightly weaker version of the theorem, which will contain all the key ideas: Theorem 12. (Kitaev) There exists some a = 2− poly(n) and b = 1/ poly(n) such that O(log n) − LHa,b is QMA-comple ...
