Researchers from Lancaster University have established that at near-absolute zero temperatures, superfluid helium-3 would give a sensation akin to a two-dimensional fluid. This finding presents a novel insight into the tactile aspect of quantum physics, with potential ramifications across various scientific sectors.
The recent research elucidates that at extremely low temperatures, superfluid 3He exhibits a two-dimensional thermal and mechanical character, suggesting significant scientific implications.
A team from Lancaster University, UK, explored the tactile sensation of superfluid helium 3He by theoretically immersing a hand into it.
Bridging the gap between the intricate realm of quantum physics and the classical physics of human sensation is among the contemporary challenges in physics.
The primary researcher, Dr. Samuli Autti, revealed the findings in Nature Communications dated November 2.
Dr. Autti expressed, “The query ‘what does quantum physics feel like upon touch?’ has remained unanswered. While the experimental conditions are complex, we can now describe the sensation of immersing one’s hand into this quantum system. This question has persisted unanswered throughout quantum physics’ century-old history. We demonstrate that, at least concerning superfluid 3He, we can provide an answer.”
The investigative procedures were executed at temperatures roughly 1/10,000th of a degree above absolute zero using a specialized cooling system. They employed a mechanical resonator, comparable in size to a finger, to inspect the intensely chilled superfluid. Photo credits: Mike Thompson at Lancaster University.

Experiencing Quantum Fluid Dynamics
Experiments were performed in a specialized cooling setup, almost 1/10,000th of a degree above absolute zero. A finger-sized mechanical resonator was utilized to investigate the frigid superfluid.
Upon agitation using a rod, the generated heat in superfluid 3He is transported away via the container’s surfaces. Predominantly, the superfluid acts like a void and remains unresponsive.
Dr. Autti explained, “If one were to insert a finger into this liquid, it would appear two-dimensional. Most of the superfluid seems vacant, with heat traversing in a two-dimensional system along the periphery, or along one’s finger.”
Scientific Ramifications
The team deduced that the core of superfluid 3He is enveloped by a separate two-dimensional superfluid that engages with mechanical instruments. It only interacts with the central superfluid upon receiving a sudden energy jolt. Hence, at minimal temperatures and energies, superfluid 3He is both thermally and mechanically two-dimensional.
“This discovery reshapes our comprehension of superfluid 3He. Its implications might surpass even the direct experience of quantum physics,” the researchers commented.
Superfluid 3He is an incredibly adaptable macroscopic quantum system in labs. Its influence spans diverse fields, including particle physics, cosmology, and quantum information processing.
A reinterpretation of its foundational structure could trigger extensive repercussions.

Woah, this is some heavy stuff! Quantum physics always goes over my head, but this seems like a big deal. i mean, feeling quantum physics? That’s next level.
This is why I love science – just when you think you’ve understood something, there’s a whole new layer to it! By the way, there’s a typo in the third paragraph. should be ‘Researchers from…’
Quantum physics…the final frontier. Jokes aside, can someone explain this in layman’s terms? Kinda hard to get my head around.
Superfluid Helium-3 behaving like a 2D fluid is interesting. but what practical applications does this discovery have? Just curious.
Hats off to the folks at Lancaster University! It’s not every day you come across research that potentially redefines our understanding of…well, reality. Need to share this with my study group.
i’ve read about superfluids in uni, but this two-dimensional sensation thing is entirely new to me. Got to dive deeper into this one.
