Electron spectrscopy on novel emergent materials
What is the most central topic of condensed mateter physics? The answer is not be unique, as the condensed matter physics is such a huge field with so many different things that go on.
However, one exciting thing is that certain textbook ideas are severely challenged and many condensed matter researcher are very excited about establishing the “physics of tomorrow's textbook.”
Here, in the Gweon group, we study such ideas, the so-called “non-Fermi liquid physics” of high temperature supercondutors and quasi-one dimensional cuprates. Generally, these exotic non-Fermi liquid states can be viewed as one consequence of the interactions of many particles. We also study topological insulators, which are a new class of quantum materials.
