The Emergence of Quantum Mechanics
... according to non-quantum mechanical, deterministic laws. Let us consider the case that also the time evolution is fundamentally discrete. The theory then can be defined in terms of an evolution operator U0 that describes one step in time. Hence, we would like to write (U0 )k = e−iHk , ...

Exceptions from this rule are possible for quantum simulators that exhibit novel, only theoretically predicted and not yet observed phenomena (simulating ≠ simulating and observing). IV.

The Canonical Approach to Quantum Gravity
... As we have seen, the initial data for the gravitational variables consist of a differentiable 3-manifold Σ, a Riemannian metric h – the configuration variable, and another symmetric second rank tensor field K on Σ – the velocity variable. However, the pair (h, K) cannot be chosen arbitrarily. This is b ...

An alternative description of Hamiltonian’s equations is in terms of observables, which in classical mechanics is simply a function A : T ∗ M → R in phase space (thus the Hamiltonian is itself an observable, known as the energy). Hamilton’s equation of motion then become d A(x(t)) = {A, H}(x(t)) dt ...
