Training for Transport and Localization in Quantum System

Abstract

Through periodic Training we can gradually buildup a reproducible responses in a disordered system where plasticity dominates over elasticity as is known in classical amorphous materials and soft matter 1, 6. Here we show that a similar concept can be extended to disordered quantum systems. Periodic electrical or mechanical driving of a disordered quantum-dot network can sculpt the effective Hamiltonian, producing either a low-energy transport valley that enhances exciton conduction, or a localized regime with many body memory like behavior. Our results establish training as a new paradigm for creating functional order in disordered quantum matter.
