  1. 3 mag 2024 · In 1934, the physicist Eugene Wigner proposed that, under certain circumstances, the electrostatic repulsion between strongly interacting electrons can break translation and orientation...

  2. 5 giorni fa · Nel 1961, il fisico teorico Eugene Wigner propose un esperimento mentale per dimostrare cosa ci sia di così complicato nell’idea di misurazione. L’esperimento consisteva nel considerare uno sperimentatore ( definito un amico nell’esperimento ) chiuso in un laboratorio ermeticamente sigillato, che compie al suo interno una misura su una particella quantistica – supponiamo sulla sua ...

  3. 5 giorni fa · In the 1930s, Eugene Wigner theorized that repulsion can maintain order as well as attraction, and 90 years later, physicists say he was right about the structure of a crystal lattice. Without protons in the mix, electrons will stay as far away from each other as possible.

  4. 6 giorni fa · Using scanning tunneling microscopy, US-based Physicists from Princeton University have imaged the elusive crystal Wigner, formed purely from the repulsive nature of electrons. This strange form of matter is one of the most important quantum phases, and has eluded direct detection for some 90 years.

  5. 2 mag 2024 · This, at least, is what the physicist Eugene Wigner predicted 90 years ago would happen. But while scientists have seen evidence of this type of crystalline lattice forming before (for example, in a one-dimensional carbon nanotube and in a quantum wire ), it had never been observed directly.

  6. 2 giorni fa · In August 1939, Hungarian-born physicists Leo Szilard and Eugene Wigner drafted the Einstein–Szilard letter, which warned of the potential development of "extremely powerful bombs of a new type". It urged the United States to acquire stockpiles of uranium ore and accelerate the research of Enrico Fermi and others into nuclear chain ...

  7. 11 mag 2024 · Eugene Wigner, another influential physicist of the era and a Nobel laureate, voiced reservations about the MWI’s empirical verifiability [12]. He questioned the feasibility of experimental tests that could validate Everett’s interpretation, casting doubt on its status as a scientifically viable theory.
