The time span from back to front is 10 pico seconds Credit: Goethe UniversityKapitza-Dirac effect utilized to reveal temporal evolution of electron waves.It was one of the most significant surprises in the history of science: In the early days of quantum physics around 100 years ago, scholars discovered that the particles that make up our matter always behave like waves. In 1933, the 2 theorists Piotr Kapitza and Paul Dirac proved that an electron beam is even diffracted from a standing light wave (due to the particles residential or commercial properties) and that disturbance impacts as an outcome of the wave homes are to be expected.Kapitza-Dirac Effect VisualizedA German-Chinese group led by Professor Reinhard Dörner from Goethe University Frankfurt has actually succeeded in utilizing this Kapitza-Dirac impact to visualize even the temporal evolution of the electron waves, known as the electrons quantum mechanical stage. According to the laws of quantum physics, these 3 possibilities together add up to a certain possibility that is reflected in the wave function of the electrons: The cloud-like space in which the electron– with a certain probability– is likely to be, collapses, so to speak, into three-dimensional slices.

Really shortly later on, the physicists fired a second pair of short laser pulses at the electrons released in this method, which also formed a standing wave at the. According to the laws of quantum physics, these 3 possibilities together add up to a particular likelihood that is reflected in the wave function of the electrons: The cloud-like space in which the electron– with a particular possibility– is most likely to be, collapses, so to speak, into three-dimensional slices.
