Nonergodic Delocalized States for Efficient Population Transfer within a Narrow Band of the Energy Landscape
We address the long-standing problem of the structure of the low-energy eigenstates and long-time coherent dynamics in quantum spin-glass models. Below the spin-glass freezing transition, the energy landscape of the spin system is characterized by a proliferation of local minima where classical dyna...
