High pressure represents a vastly unexplored phase space where novel compounds can be synthesized and recovered back to ambient conditions. We use experimental high-pressure synthesis techniques to discover completely new solid-state compounds that could underpin future advances in technology.
Modern first-principles methods can be used to accurately calculate the formation enthalpy of any given structure. We use random structure searching tools to perform high-throughput DFT calculations in search of undiscovered high-pressure phases. We also use machine learning methods to investigate how pressure can influence chemical disorder in the solid state.
Shockwaves subject materials to very high pressures over extremely short timescales, potentially offering a route toward the kinetic control of solid-state transformations. We use cutting-edge in situ X-ray diffraction methods to examine phase transformations under dynamic compression.
Systems that exhibit magnetic frustration are a direct route to exotic new states of matter dominated by quantum fluctuations. Control over these delicate quantum states is an outstanding challenge in chemistry and physics. We are using high pressures to target novel quantum phases in geometrically frustrated systems.
