Event Details & Abstract: 

Several seemingly unrelated research efforts are approaching the same central question: how does the quantum physics of interacting many-particle systems control macroscopic phenomena? This would be easy to answer if one only were able to solve the many-body Schrödinger equation exactly, a task that seems unsolvable for decades to come. The number of theoretic approaches and experimental setups are steadily increasing, which also makes the knowledgebase scattered. Therefore, it seems that one should start a thorough learning process, pedia, to combine and develop common many-body knowhow.In this talk, I present a tutorial “manybodypedia” by comparing semiconductors, atom condensates, and degenerate Fermi gases. I analyze them with correlated clusters that rigorously identify the elementary particle configurations, quasi-particles, within many-body systems. It turns out that the clusters also reformulate quantum optics in a form suitable for many-body investigations. The clusters can therefore be viewed as the “alphabets” combining the knowhow in quantum-optics and various many-body studies. As a synthesis of these concepts, I introduce the quantum-optical spectroscopy that produces unprecedented access to unexplored many-body physics.
