Quantum Physics

Physicists at New York University have developed a new type of time crystal using sound waves to suspend tiny styrofoam beads, resulting in nonreciprocal interactions that defy Newton's third law of motion. The compact, visible system oscillates in a steady rhythm and was detailed in Physical Review Letters. Researchers suggest potential applications in quantum computing and insights into biological rhythms.

An international team of scientists has identified an unexpected Island of Inversion in molybdenum-84, a nucleus with equal numbers of protons and neutrons. This discovery challenges previous beliefs that such regions occur only in neutron-rich isotopes. The finding reveals new insights into nuclear deformation and fundamental forces.

Researchers have developed a method to measure how objective reality emerges from quantum fuzziness, showing that even imperfect observers can reach consensus. This builds on quantum Darwinism, an idea proposed in 2000, by demonstrating that simple measurements suffice for agreement on classical properties. The work suggests bridges to experimental tests in quantum devices.

Researchers have harnessed quantum entanglement to link atoms across space, achieving unprecedented accuracy in measuring physical quantities. By separating entangled atomic clouds, the team improved the detection of electromagnetic fields. This breakthrough could refine atomic clocks and gravity sensors.

A team led by Holger Hofmann at Hiroshima University reported in May that a modified double-slit experiment showed single photons behaving as if in two places at once, potentially undermining the multiverse concept. The findings, which suggest the wave function guides real particle paths, have faced significant skepticism from other physicists. Despite pushback, the researchers stand by their results and continue their work.

Physicists from the KATRIN collaboration have reported no evidence for a sterile neutrino in a precise analysis of tritium decay data. The findings, published in Nature, contradict earlier experimental claims and strengthen the case against a fourth neutrino type. The experiment, based in Germany, continues to gather more data for further tests.
