Electrons can display interference effects like waves in the ocean, but this happens on extremely fast time scales. In this study, scientists observed the quantum mechanical motion of electrons in an excited molecule using an “attoclock,” which measures electron motion with a precision of hundreds of attoseconds. The experiment advances the study of electron dynamics and will improve understanding of molecular physics and quantum chemistry.

Though a cornerstone of thermodynamics, entropy remains one of the most vexing concepts to teach budding physicists in the classroom. In The Physics Teacher, co-published by AIP Publishing and the American Association of Physics Teachers, T. Ryan Rogers designed a hand-held model to demonstrate the concept of entropy for students.
Isotopes — atoms of a particular element that have different numbers of neutrons — can be used for a variety of tasks, from tracking climate change to conducting medical research.Investigating rare isotopes, which have extreme neutron-to-proton imbalances and are often created in accelerator facilities, provides scientists with opportunities to test their theories of nuclear structure and to learn more about isotopes that have yet to be utilized in application.
Neutrino mass, a crucial piece of many unresolved physics puzzles, may one day be revealed through a novel measurement system that has just proven its mettle: Cyclotron Radiation Emission Spectroscopy (CRES).
While studying random algorithms to learn their generic features and to develop new strategies to correct quantum processor errors, Cornell researchers discovered that certain classes of algorithms lead to hidden order called “spin-glass” for its analogy to window glass, which at the micro level has the disorder of liquid and the rigidity of a solid.
Scientists have observed a rare new radioactive decay mode for the first time. In this decay mode, oxygen-13 (with eight protons and five neutrons) decays by breaking into three helium nuclei (an atom without the surrounding electrons), a proton, and a positron (the antimatter version of an electron) following beta decay. The findings expand scientific knowledge of decay processes and the properties of the nucleus before the decay.

The discovery might help explain why the QGP flows like a nearly perfect liquid.
