Using anisotropic strain to probe multipolar order parameters

Abstract: Because it can be applied in-situ in a continuous fashion, and can be tailored to preserve or break selected spatial symmetries, piezoelectric devices-based strain has lately emerged as a versatile tuning parameter of quantum materials. In this talk we will focus on utilizing anisotropic strain as a probe of otherwise elusive multipolar orders in solids. Using the adiabatic AC elastocaloric effect, a compact, thermodynamic strain-based experimental technique [1,2], we study anisotropic strain effects on f electron-based multipolar orders [3,4].
