NOVEL MECHANISM. “Recent theory, however, has predicted that quantum fluctuations of electromagnetic fields could induce phonon coupling across a vacuum and thereby facilitate heat transfer.” https://www.nature.com/articles/s41586-019-1800-4 View in LinkedIn

PHONON COUPLING. “Revealing this unique quantum effect experimentally would bring fundamental insights to quantum thermodynamics and practical implications to thermal management in nanometre-scale technologies.” https://www.nature.com/articles/s41586-019-1800-4 View in LinkedIn

THEORY VALIDATED. “Here we experimentally demonstrate heat transfer induced by quantum fluctuations between two objects separated by a vacuum gap.” https://www.nature.com/articles/s41586-019-1800-4 View in LinkedIn

APPLICATIONS. “Our discovery of phonon transport through quantum fluctuations represents a previously unknown mechanism of heat transfer in addition to the conventional conduction, convection and radiation. It paves the way for the exploitation of quantum vacuum in energy transport at the nanoscale.” https://www.nature.com/articles/s41586-019-1800-4 View in LinkedIn

CYBORG SETTLERS. “They’ll harness the super-powerful genetic and cyborg technologies that will be developed in coming decades. These techniques will be, one hopes, heavily regulated on Earth – but those on Mars will be far beyond the clutches of the regulators…This might be the first step towards divergence into a new species.” (Professor Martin Rees is the astronomer royal). https://www.theguardian.com/commentisfree/2022/apr/30/space-billionaires-cosmic-earth-elon-musk-jeff-bezos?CMP=Share_iOSApp_Other View in LinkedIn

ABRUPT CHANGE. “A quantum phase transition (QPT) occurs between two competing phases of matter at zero temperature, driven by quantum fluctuations.” https://lnkd.in/gBxma-cb View in LinkedIn

QUANTUM PHASE TRANSITIONS. “Although the presence of these fluctuations is well established, they have not been locally imaged in space, and their local dynamics has not been studied so far.” https://www.nature.com/articles/s41567-018-0264-z View in LinkedIn

VISUALIZATION. “We use a scanning superconducting quantum interference device to image quantum fluctuations near the QPT from a superconductor to an insulator.” (QPT = quantum phase transitions). https://www.nature.com/articles/s41567-018-0264-z View in LinkedIn

QUANTUM ORIGIN. “We find fluctuations of the diamagnetic response in both space and time that survive well below the transition temperature, demonstrating their quantum nature.” https://www.nature.com/articles/s41567-018-0264-z View in LinkedIn
