In-Reply-To: References: Message-ID: <7a5c3018e4a566c90d7fa40dac5e26de@jyfk.fi> Dear members, You are all cordially invited to the physics colloquium tomorrow! The event starts at 10 o'clock by FYS1, and the speaker will be Tero Heikkilä from the Centre of Excellence in Quantum Materials. More information is found down below. Best, Samuli -------- Alkuperäinen viesti -------- Welcome to the Physics Colloquium! Coffee is served starting at 10:00 outside the lecture theater FYS1. Centre of Excellence in Quantum Materials Tero Heikkilä (University of Jyväskylä) On the microscopic level of single atoms or electrons, the only way to understand materials is quantum mechanics. Quantum mechanics also provides the only way to understand electronic band structures arising from the arrangement of atoms into regular lattices in solid materials, and thereby predicting many basic properties of materials, such as their electric and thermal conductivity, elastic properties, and color. Such properties are inherently of single-particle nature and quite well understood. However, there are characteristics of materials exhibiting quantum effects in the macroscopic scale, and requiring a many-body theory approach. In such quantum materials strong correlations, quantum entanglement and topology become important concepts. Improved understanding of such effects can help us tackle the major grand challenges in materials physics, such as increasing the operating temperatures of superconductors towards and beyond the room temperature, finding ways to do topological quantum computing, and finding new platforms for other new technologies. I will describe our new Finnish Centre of Excellence in Quantum Materials [1], where eight research groups from three Finnish universities and VTT employ modern experimental, theoretical and computational approache to study quantum materials and create new device applications based on them.
