Abstract:
The progress in quantum optics utilizes a unique photon state configuration for engineering of the ultimate light-matter interactions with relatively simple material systems. It results in a broad range of photonic applications including radiation sources, quantum communication, information, computing and nanotechnology. The development of the ultrafast multidimensional nonlinear spectroscopy that has been enabled by progress in ultrafast optical technology provides a unique tool for probing complex molecules, semiconductors, nanomaterials by classical light fields. I will show how new quantum phenomena in complex systems can be studied and controlled using advances in both quantum optics and nonlinear spectroscopy. In particular I investigate how the dynamics and energy characteristics of the Quantum Heat Engines such as lasers, solar cells, nanophotonic devices and biological light harvesting complexes are affected by the quantum effects. I further demonstrate how to probe and control the dynamics of these complex systems using quantum light and reveal the information, which is not accessible by conventional classical photonics. I will finally utilize the newly developed X-ray Stimulated Raman spectroscopies to control electron transfer processes and collect information about molecular systems with the attosecond precision.
简历:
Konstantin E. Dorfman was born in Russia. He completed his B.S. degree in Physics from Nizhny Novgorod State University, Russia, in 2006. In 2009 he completed his Ph.D. degree at Texas A&M University, where he investigated many-body fluctuations of Bose?Einstein Condensate. From 2010 to 2012 as a joint postdoctoral fellow at Princeton University and Texas A&M University he investigated fundamental light?matter interactions in classical/quantum optical devices, quantum heat engines, and photosynthetic light harvesting. From 2012 to 2015 he was a postdoctoral research scholar at the University of California, Irvine, where he investigated multidimensional nonlinear optical spectroscopy that utilizes quantum states of light, light range from THz to X-ray. From 2016 to 2017 as a staff scientist in Singapore Agency for Science, Technology and Research (A*STAR) he worked on various aspects of X-ray photonics. He is now a professor of physics at State Key Laboratory of Precision Spectroscopy, East China Normal University, Shanghai. His scientific interests include atomic, molecular, optical, and chemical physics, energy and charge transport processes, quantum optics and electronics, X-ray optics, relativistic and Terahertz physics, statistical mechanics, many-body theory, quantum photovoltaics, and semiconductor physics. Dr. Dorfman published over 50 research articles in scientific journals with 23 as a first author and 24 as a corresponding author including high impact publications in Review of Modern Physics, PNAS, PRL, Nature Communications, JACS and Chemical Reviews.
