Michigan State hosts major research conference on quantum materials
Michigan State University is hosting a major research conference—the 7th Conference on Photoinduced Phase Transitions and Cooperative Phenomena (PIPT7) this month. The conference is an international meeting bringing together leading experimentalists and theorists in the field of photoinduced phase transitions in cooperative systems.
Due to the ongoing pandemic, the scientific committee recently decided to pivot the PIPT7 Conference from an in-person event to a series of virtual mini-symposia , which will be held over a two-week span, running from Nov. 8 through Nov. 18 to accommodate the participants from the United States, Europe and Asia.
This year’s conference will focus on control science of quantum materials. These quantum materials, often also referred to as strongly correlated electron materials, are featured by their complex phase diagrams where multiple electronic phases often occur adjacently. The rich variety of ordered states—including superconductivity, electronic crystals, magnetic orders, and collective topological states—emerge as a consequence of astounding properties of quantum mechanics. The research on quantum materials has gained momentum recently driven by the desire to harness the functionalities beyond the conventional semiconductors.
In the past several decades, the intriguing discoveries of the quantum phases strongly interacting with light fields on the ultrafast timescales defy the intuitive understanding of how electronic materials shall behave and thus gave rise to a new field of ultrafast material research, now dubbed photoinduced phase transition (PIPT).
Whereas ultrafast nonthermal control of quantum materials is poised to new ways of engineering quantum phases, the mechanism to exerting control is rooted in nonequilibrium quantum many-body physics. This year’s conference aims to connect fundamental research to practical applications that include harnessing the delicate quantum phases for future electronics and photonics, including quantum and information technologies.
As the fundamental interactions that define the quantum realm start at the ultrafast timescale and sub-nm scale, technological advances of modern spectroscopy and imaging tools also play essential roles for the development of this relatively young field, and thus will also be discussed.
