The 2018 "Fundamental Physics of Ferroelectrics Workshop,” is the 29th in the series of workshops that has gathered the world’s leading theorists and experimentalists working in the field of ferroelectrics and related materials every year since 1990. This year we again meet at the Carnegie Institution for Science headquarters in Washington, D.C., just 9 blocks north of the White House in the heart of the nation's capital. The meeting includes two and a half days of oral sessions, a poster session, and a banquet.
