Dr. Erez Berg has conducted creative and influential theoretical studies to gain valuable insights into quantum materials – materials bearing macroscopic quantum physics phenomena that cannot be completely understood with concepts from contemporary physics textbooks. His research topics are wide-ranging, from the decades-old debate about the theory underlying the functioning of high-temperature superconductors, to increasing our understanding of novel topological phases of matter, a research field that has emerged in the past decade that identifies unique electronic properties of materials arising from the special geometries (or “topologies”) in which the electrons arrange themselves. These exotic phenomena, which could enable new and important techniques to next generation electronics, have not yet been used in real world applications due to the poor understanding of the physics principles behind them.

During his earlier work, Dr. Berg undertook a landmark computational method to study an important phenomenon, called metallic quantum criticality, which is commonly seen in many quantum materials. Dr. Berg overcame the obstacle that hindered previous theoretical studies and presented a controllable physics description of this phenomenon, an important first step toward a complete understanding of its mechanism, which has key implications in the theory of high-temperature superconductors. Recently Dr. Berg’s work has pushed the conceptual frontiers of topological quantum materials in two new directions. He spearheaded a novel method that for the first time realized topological phenomena in an otherwise non-topological quantum system by applying an external driving force, which led to immediate experimental implementations in real materials. He also led the theoretical search for new physical platforms for topological superconductors, which are very promising for storing and manipulating quantum information. These achievements, along with a number of other research fronts, testify to his significant impact on a wide breadth of important central questions in the field.

“The great thing about working on quantum materials is not just that you study fascinating phenomena, but also that you get to talk to so many enthusiastic, bright people who share your interests.”
