معرفی
Yaakov Fein is a quantum-physics researcher at the University of Vienna, active within the interdisciplinary research cluster Quantum Optics, Quantum Nanophysics and Quantum Information. Operating from the Währinger Straße campus, he explores fundamental aspects of matter-wave physics using progressively more massive nanoparticles and molecules.
His academic qualifications include a BA, MA and an MSc, and he is reachable at yaakov.fein@univie.ac.at; however no explicit faculty rank is supplied in the text.
Fein’s experimental and theoretical agenda centres on high-mass matter-wave interferometry, quantum-assisted metrology, and nano-scale magnetism. By levitating or beam-loading nanoparticles—ranging from metals to functionalised biomolecules—into long-baseline interferometers, he investigates quantum superposition limits, decoherence mechanisms, and novel sensing protocols that exploit干涉条纹位移 for measuring electromagnetic and inertial quantities.
Across more than two-dozen peer-reviewed works (2017-2024) a clear trend emerges: continual push toward heavier masses (>25 kDa), longer interferometer baselines, and incorporation of internal degrees of freedom (spin, diamagnetism, polarizability) to boost sensing precision. Studies also encompass historical perspectives on Otto Stern’s legacy and foundational tests of wave-function collapse, positioning the research at the intersection of quantum optics, metrology, and quantum foundations.
