Quotes:
> “Performing magnetic resonance is like trying to move a particular ball on a billiard table by lifting and shaking the whole table,” he says. “We'll move the intended ball, but we'll also move all the others.
> “The breakthrough of electric resonance is like being handed an actual billiards stick to hit the ball exactly where you want it.”
This could allow much more compact MRI scanners, vast improvements in quantum computing, chemistry or mining, and of course to design fundamentally new science experiments.
> “This landmark result will open up a treasure trove of discoveries and applications,” says Professor Morello. “The system we created has enough complexity to study how the classical world we experience every day emerges from the quantum realm. Moreover, we can use its quantum complexity to build sensors of electromagnetic fields with vastly improved sensitivity. And all this, in a simple electronic device made in silicon, controlled with small voltages applied to a metal electrode.”
If you don't know about NER (Nuclear Electric Resonance), take comfort in knowing that Pr. Morello did not either. We're “rediscovering” this rather dead field. What a fantastic serendipitous discovery, isn't it?
- dang 7y agoUrl changed to that from https://www.nature.com/articles/s41586-020-2057-7 https://www.nature.com/articles/s41586-020-2057-7. Thanks! For something like this where so few readers can understand the specialist article, it's preferable to link to the best popular summary.
- K0SM0S 7y agoI'll keep that in mind. Thanks for the guideline! — and proper title/link.
- whatshisface 7y agoI wouldn't expect anything to happen for MRI scanners because they are putting the electric fields over tiny patches on a silicon chip. The whole point of the design is that the effect doesn't extend very far past the tiny area where it's meant to be.
- amelius 7y agoBut you can create electric fields over large areas if you wish to do so, and it's probably easier and cheaper than creating large magnetic fields. I suspect there are other downsides though.
