Can topological quantum materials be used for energy conversion and storage?

We describe the open problems and the potential applications of TQMs in water splitting, batteries, supercapacitors and other prospects in energy conversion and storage. Topological quantum materials host protected, high-mobility surface states which can be used for energy conversion and storage.

What are quantum batteries?

Quantum batte-ries are energy storage devices that utilize quantum mechanics to enhance performance or functionality. While they are still in their infancy, with only proof-of-principle demonstrations achi-eved, their radically innovative design principles offer a potential solution to future energy challenges.

What is integrable quantum phase diagram?

Such integrable model shows a rich quantum phase diagram that emerges through a mapping of the spins onto auxiliary fermionic degrees of freedom. We consider a charging protocol relying on the double quench of an internal parameter, namely the strength of the dimerization, and address the energy stored in the systems.

What is quantum entanglement?

This purely quantum mechanical phenomenon means that entanglement can be a considered a resource from which work can be extracted. These correlations underpin the unique prop-erties of quantum batteries. Quantum batteries are a redesign of energy storage devices from the bot-tom up.

Can quantum computing be used to design battery systems?

As a tool to characterize and design battery systems, one can envision quantum computing approaches would first be used to complement DFT's strengths and shortcomings. DFT can run into difficulty in modeling systems and processes involving large variations in electronic structure.

How does a quantum chip work?

The quantum chip is mounted on the bottom and is controlled via microwave signals sent through superconducting wires. The full promise of intermittent renewable energy technologies to displace significant greenhouse gas emissions requires large quantities of reliable and cheap energy storage capacity to come online at an accelerated pace.
