Research into Luttinger's theorem, which connects a system's particle capacity with its response to low-energy excitations, has revealed its failure in specific cases of strongly correlated phases of matter, particularly in topological insulators, highlighting a fundamental connection between particle behavior and quantum matter classification. A recent study by Lucila Peralta Gavensky, Subir Sachdev, and Nathan Goldman has shown that the failure of Luttinger's theorem and the classification of insulating states of matter are connected, with the Ishikawa-Matsuyama invariant fully characterizing correlated insulators when Luttinger's theorem is satisfied, but requiring corrections when it is violated, shedding light on the emergence of exotic phenomena in strongly correlated quantum matter.

Physicists at the National University of Singapore have developed a technique to precisely control the alignment of supermoiré lattices, which are formed when two periodic structures are overlaid with a twist angle. By using a set of golden rules, the researchers have successfully achieved the controlled alignment of hBN/graphene/hBN supermoiré lattices, expanding the range of tunable material properties and potential applications. The technique involves a "30° rotation technique" and a "flip-over technique" to control the alignment of the layers. The researchers have also formulated three golden rules to guide the use of their technique. This advancement could accelerate the development of next-generation moiré quantum matter.

Researchers from EPFL and the University of Innsbruck have made a breakthrough in quantum physics by creating a new type of matter called a "density wave" in a cold atomic gas. By using an optical cavity to allow atoms to interact at long distances through the exchange of photons, the researchers were able to observe the self-organization of particles into a regular pattern. This discovery could advance our understanding of quantum matter and have implications for quantum-based technologies such as high-temperature superconductivity and quantum computing.

Scientists at EPFL and the University of Innsbruck have made a breakthrough in creating a crystalline structure called a "density wave" in an atomic gas, which can help us better understand the behavior of quantum matter. The researchers used an optical cavity to cause the particles in the Fermi gas to interact at long distance, allowing the atoms to collectively organize into a density wave pattern. This breakthrough can impact not only quantum research but quantum-based technologies in the future, such as high-temperature superconductivity and quantum computers.

Researchers at the University of Toronto have developed a theoretical model to understand the behavior of "strange metals," which exhibit complex states of matter due to the intertwined properties of electrons. The model describes the interactions between subatomic particles in non-Fermi liquids and provides insight into symmetry breaking, a fundamental process found in all of nature. The research could lead to new ways to control and tune the properties of quantum materials, including high-temperature superconductors and graphene devices, which could shape the next generation of quantum technology.
