Perturbation Independent Decay of the Loschmidt Echo in a Many-Body System
When a qubit or spin interacts with others under a many-body Hamiltonian, the information it containsprogressively scrambles. Here, nuclear spins of an adamantane crystal are used as a quantum simulator tomonitor such dynamics through out-of-time-order correlators, while a Loschmidt echo (LE) asses...
