Phase transition of a perovskite strongly coupled to the vacuum field

The hysteresis and dynamics of the phase transition of the perovskite salt [Pb( ii )I 4 2− ,(C 12 H 25 NH 3 + ) 2 ] is shown to be significantly modified when strongly coupled to the vacuum field inside a micro-cavity. The transition barrier is increased and the hysteresis loop is enlarged, demonstr...

Description
Summary:The hysteresis and dynamics of the phase transition of the perovskite salt [Pb( ii )I 4 2− ,(C 12 H 25 NH 3 + ) 2 ] is shown to be significantly modified when strongly coupled to the vacuum field inside a micro-cavity. The transition barrier is increased and the hysteresis loop is enlarged, demonstrating the potential of controlling the electromagnetic environment of a material. Hysteresis and energy barrier of a phase transition are shown to be significantly modified by strong coupling (red curves).
