Speaker: Ciarán Hickey (UCD)
Abstract: Many of the most important and widespread techniques in use today in probing many-body systems can be understood within the framework of linear response. However, though incredibly powerful, in some cases linear response can be simply blind to the underlying physics at play, unable to distinguish between different potential possibilities. One of the most exciting recent developments in pushing beyond this linear response regime has been the advent of non-linear spectroscopy as a tool to study quantum many-body systems. In this talk, I will discuss how non-linear response can be used to reveal new information about frustrated quantum magnets.
