Biography

Research Statement:

I am broadly interested in theoretical condensed matter physics, in particular, quantum mechanical aspects of condensed matter systems in the areas of nanoscale physics and strongly correlated systems, as seen in the transport and entanglement of electrons. As electronic devices become smaller and smaller, quantum effects have a greater influence on their electronic properties. At the same time, we are seeking to exploit quantum effects to enable quantum computation and quantum communication in next-generation electronics, as these quantum effects are much more powerful than classical alternatives. The target systems so far include quantum nanowires, the quantum Hall effect, unconventional superconductors, carbon-related systems such as carbon nanotube and graphene, and more recently, topological insulators and topological superconductors. At Illinois, I am planning to work further on topological phenomena in condensed matter physics, with more emphasis on strong electron correlations, in particular, a search for new topological superconductors in unconventional superconducting systems.

Shinsei Ryu, a University of Illinois assistant professor of physics, was named one of ten early-career scientists who are "on their way to widespread acclaim", in an article in Science News, an online publication of the Society for Science & the Public. In theoretical condensed matter physics, the systems can be so complex that the goal isn’t finding the right answers, Ryu says, “it’s asking the right questions.” Quantum applications such as computers rely on consistency — the same question should yield the same answer every time. But the quantum interactions between electrons are often unpredictable, so Ryu hunts for measurements that reliably return the same value again and again. He likens the systems to a doughnut shape. The curvature of the doughnut’s surface can change when external forces press in, but the number of holes in the doughnut stays the same. These kinds of robust properties will make accurate quantum computing possible, he says.
