Ultra-low temperature (ULT) technologies have been developed shoulder to shoulder with helium physics research (where the ULT physics research originally started), and they have found themselves with much broader applications now. This talk will start with an example of applying ULT technology in classical He-3 physics research, followed by a few examples of its applications in contemporary frontier Physics research, such as ULT-STM systems in high magnetic fields, Angle-resolved photoemission spectroscopy (ARPES) below 1K, quantum computing, cosmology physics, etc.
Dr. Zuyu Zhao received his B.S. degree from Fudan University in 1982. He came to US in 1983 with the World Bank Scholarship and graduated from Northwestern University with Ph.D. degree of physics in 1990. He then spent two and half year working at Harvard University as post-doc and set a new lab pursuing Bose-Einstein condensation on spin polarized hydrogen. Dr. Zhao joined Janis Research Company in 1993 and focused on developing custom ultra-low temperature facilities for the research and science community. He is currently the Board of Director, Executive Vice President - Principal Scientist of Janis. He developed the first high power He-3 cryostat with sample in UHV space for Angular-Resolved Photoemission Spectroscopy (ARPES) Applications in mK range in 2008 and co-developed the first top-loading 10mK (high B/T) dilution refrigerator system with sample UHV compatible space for STM application in 2009. He also developed the first bottom-loading UHV compatible He-3 system with sample in UHV for STM application in 2008 and developed the bottom-loading 10mK dilution refrigerator system with sample UHV compatible space for STM application in 2009. He won twice NASA Public Service Achievement Awards (in 1996 and 2000) and NASA SBIR Phase-I Award in 2004. He was the member of the AIP <<Physics Today>> Advisory Committee Member from 7/1/2007 to 6/30/2013.
