Article Synopsis
- Quantum dynamical localization in higher-dimensional Hamiltonian systems can be disrupted by classical drift, allowing quantum wave packets to explore more of the Arnold web than previously thought.
- This classical drift happens when resonance channels expand, leading towards chaotic regions or intersections with other channels, which can eliminate dynamical localization under strong conditions.
- The study shows that this drift-induced transition to delocalization is universal, characterized by a single transition parameter, with numerical evidence provided through simulations of a kicked Hamiltonian in a four-dimensional phase space.
