Phase transition of a perovskite strongly coupled to the vacuum field
Abstract
The hysteresis and dynamics of the phase transition of the perovskite salt [Pb(II)I42−,(C12H25NH3+)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.
