Quantum Tornadoes Reveal Superfluidity in Supersolid Matter

Physicists at the University of Innsbruck have successfully imaged quantum vortices in a supersolid, confirming the existence of this paradoxical phase of matter that combines properties of both solids and superfluids. This discovery, published in Nature, provides crucial evidence for supersolids, which may also exist in the interiors of neutron stars. The research could help explain phenomena in extreme cosmic environments, such as pulsar glitches, and advance understanding of exotic phases of matter like high-temperature superconductors.

"Experimental Evidence: Discovery of Graviton-like Particles in Quantum Material"

Scientists from Columbia, Nanjing University, Princeton, and the University of Munster have presented the first experimental evidence of collective excitations with spin called chiral graviton modes (CGMs) in a semiconducting material, bridging the gap between quantum mechanics and Einstein’s theories of relativity. The discovery, published in Nature, could potentially connect high energy physics and condensed matter physics, shedding light on the mysterious nature of gravity. The research, which builds on the legacy of late Columbia professor Aron Pinczuk, marks a significant step toward a better understanding of the universe and its fundamental forces.

"New Exotic State of Matter Discovered through Subatomic Particle Compression"

Physicists have discovered a new state of matter called a "bosonic correlated insulator," which takes the form of a highly ordered crystal of subatomic particles. The discovery could lead to the creation of many new types of exotic materials made from condensed matter. The researchers used a lattice of tungsten disulfide and tungsten diselenide to create the new state of matter by pushing excitons together until they were so densely packed that they could no longer move. This is the first time this new state of matter has been created in a "real" matter system, providing new insight into the behavior of bosons.

Bosonic Material Unveiled: Physicists Discover Exotic State of Matter

Physicists have discovered a new state of matter, a "bosonic correlated insulator," through the interaction of bosonic particles called excitons. This research could pave the way for new understandings in condensed matter physics and the creation of new bosonic materials. The unique material is a highly ordered crystal of bosonic particles called excitons. The creation of this exotic state of matter proves that the researchers' moiré platform and pump-probe spectroscopy could become an important means for creating and investigating bosonic materials.
