Searching for axion dark
Yannis K. Semertzidis
Director of Center for Axion and Precision Physics, IBS, KAIST
Axions are a leading dark matter candidate filling all vacuum around us. Its exact mass is unknown, but an axion in the mass range 0.2 GHz to 200 GHz would fit the bill for a cold dark matter candidate. Axions convert to electromagnetic field in the presence of a strong magnetic field and a resonant structure. The lower mass spectrum can be probed by resonant microwave cavities and most effectively by using the TM010 mode. For higher mass range the open resonators may seem more effective where there is a need for a quantum limited noise microwave amplifiers. I will talk about the research program at the Center for Axion and Precision Physics research as well as the future program.
