Limit on Electric Dipole Moment

Authors: George Rajna

The most precise measurement yet of the electron's electric dipole moment (EDM) casts doubt on " split supersymmetry " and some other theories of physics beyond the Standard Model of particle physics. [21] In a new study, researchers at Northwestern, Harvard and Yale universities examined the shape of an electron's charge with unprecedented precision to confirm that it is perfectly spherical. [20] Recently, extensive study shows that the parity-time symmetry breaking in open systems leads to exceptional points, promising for novel applications leasers and sensing. [19] A recent discovery by William & Mary and University of Michigan researchers transforms our understanding of one of the most important laws of modern physics. [18] Now, a team of physicists from The University of Queensland and the NÉEL Institute has shown that, as far as quantum physics is concerned, the chicken and the egg can both come first. [17] In 1993, physicist Lucien Hardy proposed an experiment showing that there is a small probability (around 6-9%) of observing a particle and its antiparticle interacting with each other without annihilating—something that is impossible in classical physics. [16] Scientists at the University of Geneva (UNIGE), Switzerland, recently reengineered their data processing, demonstrating that 16 million atoms were entangled in a one-centimetre crystal. [15] The fact that it is possible to retrieve this lost information reveals new insight into the fundamental nature of quantum measurements, mainly by supporting the idea that quantum measurements contain both quantum and classical components. [14] Researchers blur the line between classical and quantum physics by connecting chaos and entanglement. [13] Yale University scientists have reached a milestone in their efforts to extend the durability and dependability of quantum information. [12]
