Research Areas
Our group's research at UT Austin lies at the intersection of condensed matter physics, quantum optics, and quantum information. We employ approaches in quantum optics and information, as well as conventional techniques in condensed matter physics, to uncover new properties of materials at the quantum level. We conduct fundamental theoretical research which is curiosity-driven but has high potential for applications in quantum computing, advanced electronics and photonics, and more.
Topological Phases of Matter
Topological phases of matter are exotic quantum phases in certain materials that exhibit properties governed by global topological invariants, which remain robust even in the presence of imperfections. In our group, we discover and characterize new topological phases, which play a critical role in phenomena such as the emergence of protected surface states, quantized material properties, and correlated phases in Moiré systems. Our research aims to understand these exotic phases and harness their potential for applications in quantum computing and advanced materials.
Many-Body Physics
Many-body physics examines the collective behavior that emerges when a large number of particles interact. Our group focuses on strongly correlated electronic systems, where quantum geometry often plays a crucial role in phenomena such as unconventional superconductivity and fractional topological phases. We aim to uncover new principles in many-body quantum behavior that could lead to breakthroughs in high-temperature superconductivity and other exotic correlated phases of matter.
Light-Matter Interactions
Electromagnetic interactions are the most fundamental interactions in materials consisting of electrons and atoms. The interaction between matter and an oscillating electromagnetic field (that is, light) thus reveals many aspects of material properties. Our group investigates how the quantum geometry and topology of materials influence light-matter interactions. By understanding these effects, we aim to understand the quantum phases of matter and how to manipulate them using optical methods.
