Abstract
In 2023/2024 we celebrate the centenary of Louis de Broglie concept of matter waves. It inspired Erwin Schrödinger’s wave equation and a century of studies on quantum foundations and technologies.
While Louis de Broglie still believed to have solved “probably … all problems related to quanta”[1], the very nature of the quantum wave has remained a matter of debate.
Throughout the years, our research group at the University of Vienna has been running matter-wave interference experiments with atoms [2], hydrocarbons [3], organic clusters [4], biomolecules [5-8], macromolecules [8] in more than half a dozen interferometer configurations,
exploring the limits of quantum macroscopicity as well as new applications in bio-physical chemistry and the material sciences. We will review these efforts, recent progress in matter-wave interferometry with massive nanoparticles [10,11] and some prospects for the future.
