Professor Jigang Wang, Department of Physics & Astronomy, Iowa State University and the Ames National Laboratory-U.S. DOE, will speak about "Quantum Coherence at Space-Frequency Limit."

The challenge of pushing the switching speed-limit and integration density of today’s logic and memory devices into the terahertz (THz, 1012 hertz) and sub-20 nanometer regime underlies the entire field of information processing, recording, storage and communication. We approach this challenge via developing an Extreme Quantum Terahertz nanoscope that operate at temperatures down to liquid helium temperature and high magnetic fields. The simultaneous space, energy and time visualization under these extreme conditions breaks new ground for coherent control of quantum matter.
