Tracking down quantum fluctuations of the vacuum to explore the limits of physics
Absolutely empty—that is how most of us envision the vacuum. Yet, in reality, it is filled with an energetic flickering: the quantum fluctuations.

Some of the greatest unanswered questions about the nature of the universe are related to light, the vacuum (i.e. space where neither matter nor radiation exists), and their relationship with time. In the past, physicists ...
For decades, scholars have believed that the quantum statistical properties of bosons are preserved in plasmonic systems, and therefore will not create different form of light.
