5 hari yang lalu · In this study, we investigate the effects of AC-magnetic fields on two-dimensional (2D) Dirac electrons and report the emergence of new states and new transport phenomena. In a magnetic field that temporarily changes its direction, an electron nor a hole can sorely complete a cyclotron orbit.
2 hari yang lalu · Bell's theorem is a term encompassing a number of closely related results in physics, all of which determine that quantum mechanics is incompatible with local hidden-variable theories, given some basic assumptions about the nature of measurement."Local" here refers to the principle of locality, the idea that a particle can only be influenced by its immediate surroundings, and that interactions ...

[25] Neutron lifetime puzzle : While the neutron lifetime has been studied for decades, there currently exists a lack of consilience on its exact value, due to different results from two experimental methods ("bottle" versus "beam").
3 hari yang lalu · Dirac's paper introduced an equation, later known as the Dirac equation, that unified quantum mechanics, special relativity and the then-new concept of electron spin, to explain the Zeeman effect. Drawing on the body of experimental evidence, Oppenheimer rejected the idea that the predicted positively charged electrons were protons .
