Recent physics studies have found that light can sometimes flow in unexpected ways, behaving like a so-called "superfluid." ...

New techniques and refinements of older ones are needed to reach <1 K for quantum-computing cooling. Part 1 provided an ...

Superfluid helium exhibits a range of remarkable physical phenomena that challenge conventional fluid dynamics and heat transfer theories. At temperatures near absolute zero, helium transitions ...

Quantum sensors have become important tools in low-energy particle physics. Michael Doser explores opportunities to exploit their unparalleled precision at higher energies.

Did Georgia ban helium balloon releases? Not quite. Here’s what the new law actually says and why social media is confused.

Traditionally, this fusion results in high-energy "alpha particles" (helium-4 nuclei), but those particles can be prone to escape, which can cool the plasma and halt the entire process.
