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.”
