    so ein Schema zur Messung des Einsteinschen Äquivalenzprinzip für ein Quantensystem entwickeln und im Experiment testen. Ein Quantenlabor ersetzt den Schiefen Turm von Pisa In der klassischen Physik beschreibt die berühmte relativistische Formel E=mc2, wie die Gesamtmasse eines Systems von seiner Energie abhängt. Im Gegensatz zur klassischen Theorie muss in der Quantentheorie ein System jedoch nicht immer eine bestimmte Energie haben. Es kann gleichzeitig zwei oder mehrere ...

    Schrödinger’s Letter to Edington: Reconciling Mach’s and Boltzmann’s Philosophy
    13.09.2021
    had significantly influenced Schrödinger’s intellectual formation and philosophical standpoint. Schrödinger adopted Mach’s epistemological view of science theories, according to which “sensations” are empirical building blocks of scientific knowledge [2]. At the same time, Schrödinger accepted Boltzmann’s methodological thesis that visualisation (German: Anschaulichkeit ) is a necessary criterion for understanding. However, he held that this Anschaulichkeit should not be ...

    Precision Metrology with Photons, Phonons and Spins: Answering Major Unsolved Problems in Physics and Advancing Translational Science
    10.07.2023
    fundamental constants, searches for wave-like dark matter and test of quantum gravity. This work includes: 1) Our study and application of putative modified physical equations due to beyond standard model physics, to determine possible new experiments: 2) An overview of our current experimental program, including status and future directions. This includes experiments that take advantage of axion-photon coupling and axion-spin coupling to search for axion dark matter. High ...

    FELIX EHRENHAFT: A DISONANT VOICE FROM VIENNA – OR THE COST OF BEING AGAINST PARADIGMS
    02.02.2021
    allowed him to measure the electron charge, for which he won international prestige, achieving an accuracy superior to other scientists, as Robert Millikan. However, his fame declined as Ehrenhaft insisted on having also found fraction values, like 2/3 or 4/3 of the “elementary” charge. He seemed with this result to side with Ernst Mach, in terms of denying the electron the status of an indivisible particle. He fought with the Austrian artillery during Word War I, and ...

    "Qutrit": Complex quantum teleportation achieved for the first time
    19.08.2019
    In quantum physics, unlike in classical computer science, "0" and "1" are not an 'either/or' – both simultaneously, or anything in between, is also possible. The Austrian-Chinese team has now demonstrated this in practice with a third possibility "2". Novel experimental method It has been known since the 1990s that multidimensional quantum teleportation is theoretically possible. However: “First, we had to design an experimental method for implementing high-dimensional ...
