Researchers observe supersolid behavior in solid helium-4, where a small fraction of atoms exhibit zero friction and nonclassical rotational inertia. The discovery challenges the accepted picture of crystalline solid 4-He and forces theorists to revise their understanding of quantum mechanics.
Researchers at Duke University have discovered signs of superfluid hydrodynamics in a degenerate gas of lithium-6 fermionic atoms. The findings suggest that these atoms can exhibit behavior characteristic of a fermionic superfluid, providing new insights for studying high-temperature superconductivity.
Researchers Chan and Kim create a supersolid by compressing helium-4 gas into a glass disk with miniature pores at extremely low temperatures. The experiment suggests that all three states of matter can enter the 'super' state, known as Bose-Einstein condensation.
Researchers at Duke University have created a strongly interacting fermi gas by cooling lithium-6 atoms to near absolute zero. The resulting gas displays unusual behavior, including rapid expansion in one direction and no movement in another, challenging existing theories of superfluidity.
Researchers at UC Berkeley create a superfluid analog of superconducting SQUID, detecting quantum oscillations in helium-3 and measuring tiny changes in rotation. This breakthrough enables potential ultrasensitivity in gyroscopes and testing predictions from Einstein's general theory of relativity.
Researchers have found that a cluster of 60 helium atoms is sufficient to create a superfluid, defying gravity and exhibiting macroscopic properties. This discovery was made possible by the development of new methods to explore superfluidity on a microscopic scale.
