He has a two-dimensional thermal and mechanical nature at ultra-low temperatures, which could have profound scientific implications.The interface between the exotic world of quantum physics and classical physics of the human experience is one of the major open problems in modern physics.Dr.
“These experimental conditions are extreme and the techniques complicated, but I can now tell you how it would feel if you could put your hand into this quantum system. “Nobody has been able to answer this question during the 100-year history of quantum physics. We now show that, at least in superfluidThe experiments were carried out at about a 10000th of a degree above absolute zero in a special refrigerator and made use of mechanical resonator the size of a finger to probe the very cold superfluid; Dr Samuli Autti at Lancaster University.
Dr. Autti said: “This liquid would feel two-dimensional if you could stick your finger into it. The bulk of the superfluid feels empty, while heat flows in a two-dimensional subsystem along the edges of the bulk — in other words, along your finger.”He is wrapped by an independent two-dimensional superfluid that interacts with mechanical probes instead of the bulk superfluid, only providing access to the bulk superfluid if given a sudden burst of energy.
