Ultrafast Dynamic Control of Metamaterials and Emergent phases in Quantum materials

日期:2017-12-27 阅读:526


For ages, light-matter interaction from physicist’s perspective means optical spectroscopy of materials and modulating light with functional materials. In the past two decade, the profound advancement in material science and ultrafast science has re-defined the terminology, and extended “light-matter interaction” to a richer land that includes active control of materials (classic and quantum) with photons. I will show examples that demonstrate active control of both classical and quantum materials, including strong THz filed induced field electron emission, THz modulated semiconductor metamaterials, photo-induced metastable state in CMR transition metal oxides.


Dr. Jingdi Zhang received his B.S. in Physics at University of Science and Technology of China, and then Ph.D. in Physics at Boston University. He is now a postdoctoral researcher at Department of Physics, University of California, San Diego. His main research interest is the study of strongly correlated electron materials (colossal magnetoresistance, High-Tc superconductors and heavy-fermion systems), metamaterials and plasmonics using ultrafast spectroscopy (THz, mid-infrared and optical), infrared nano-imaging & nano-spectroscopy.
