Adiabatic Theorem for Quantum Spin Systems
Adiabatic Theorem for Quantum Spin Systems
The first proof of the quantum adiabatic theorem was given as early as 1928. Today, this theorem is increasingly applied in a many-body context, e.g., in quantum annealing and in studies of topological properties of matter. In this setup, the rate of variation ϵ of local terms is indeed small …
