Training for Transport and Localization in Quantum System

TL;DR

This paper demonstrates that periodic training can be used to control transport and localization in disordered quantum systems, enabling the creation of functional quantum states through sculpting the effective Hamiltonian.

Contribution

It extends the concept of training from classical amorphous materials to disordered quantum systems, showing how periodic driving can induce desired quantum behaviors.

Findings

Periodic driving creates transport or localized regimes in quantum-dot networks.

Training induces many-body memory effects in disordered quantum matter.

Effective Hamiltonian can be sculpted to enhance exciton conduction or localization.

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.
