Yazdani_CV
Yazdani is known for his research in advancing our understanding of emergent quantum phenomena by application and development of high-resolution microscopy techniques to directly visualize highly entangled quantum states of matter.
He graduated from UC Berkeley with a degree in physics and from Stanford University in 1995 with a Ph.D. in applied physics. After working as a postdoctoral scientist at IBM, he started his own independent research group at the University of Illinois in Urbana-Champaign before joining Princeton University's Physics Department in 2005. He has held visiting professorships at Stanford and at Cambridge University (Trinity College) in the UK and has been a Loeb Lecturer at Harvard.
For his research accomplishments, he has been recognized by several awards and honors including a Humboldt research award and was elected a fellow of American Physical Society, American Association for Advancement of Science, and American Academy of Arts and Sciences. In 2019, he was elected a member of the National Academy of Sciences and the APS awarded him the 2023 Oliver E. Buckley Condensed Matter Physics Prize, which recognizes outstanding theoretical or experimental contributions to condensed matter physics. He has advised more 30 graduate students and postdoctoral fellows.
Yazdani Lab Research Program: Harnessing the power of quantum microscopy techniques
A goal at the forefront of condensed matter physics is understanding how quantum phases of matter emerge from interactions among electrons or from topological properties of electronic states. These quantum phases can have novel electronic properties and host unusual quasiparticles, the control and manipulation of which may lead to new quantum technologies.
Our group's focus is to harness the power of high-resolution scanning quantum microscopy techniques to understand such novel phases of matter. These studies have provided information that is impossible to obtain using conventional macroscopic averaging techniques typically used in condensed matter physics. For example, scanning tunneling microscopy (STM) techniques can directly visualize electronic wavefunctions in quantum materials, allowing us to understand the nature of new quantum phases and their excitations.
Our group not only applies well established techniques of quantum microscopy across a wide range of material platforms, but we also develop new microscopy methods and tools.
