Nanowerk  June 21, 2024 Symmetry breaking across phase transitions often causes changes in selection rules and emergence of optical modes which can be detected via spectroscopic techniques or generated coherently in pump-probe experiments. An  international team of researchers (Switzerland, Poland, Czech Republic, Italy) demonstrated that in magnetite (Fe3⁢O4) light excitation coupled to the critical fluctuations of the charge order and coherently generated structural modes of the ordered phase above the critical temperature of the Verwey transition. According to the researchers their methodology represents an effective tool to study the real-time dynamics of critical fluctuations across phase transitions… read more. TECHNICAL […]
