An international team of researchers (Germany, Italy, UK, Switzerland, USA – University of Pittsburgh, Pennsylvania State University, Israel) has demonstrated a way to observe physical phenomena proposed to exist in higher-dimensional systems in analogous real-world experiments. Using ultracold atoms trapped in a periodically modulated two-dimensional superlattice potential, the scientists could observe a dynamical version of a novel type of quantum Hall effect that is predicted to occur in four-dimensional systems. The research provides the first experimental glimpse into the physics of higher-dimensional quantum Hall systems, which offer many fascinating prospects… read more. TECHNICAL ARTICLE
