Researchers at OIST successfully moved a levitating, centimeter-wide diamond using the force generated by electron spin alone, directly observing a quantum effect on an object subject to gravity. This achievement sets a new baseline for studying the boundary between classical and quantum physics.
Researchers at UC Santa Barbara extend search for quantum black holes at the LHC, using a novel method to search for new particles. The study informs theories on spacetime structure and provides an exclusion limit on the existence of these tiny objects.
Effective field theories offer a unified description of complex systems, including atomic nuclei and biological systems. The collected studies demonstrate the relevance of these ideas to low-energy nuclear processes, paving the way for new advances in this field.
Theoretical physicists led by the University of Oregon's Stephen Hsu have found indications that grand unified theories may be merging into a single unified field. However, their research also suggests that this process could be slowed down or blocked by quantum fluctuations in space-time, making it more challenging to detect.
