AbstractPhase diagrams of materials are typically based on a static order parameter, but it faces challenges when distinguishing subtle phase changes, such as re-ordering. Here, we report a dynamic nonequilibrium order parameter termed re-order parameter to determine subtle phases and their transitions in interacting magnets. The dynamical precession of magnetization, so-called magnon, premises as a reliable re-order parameter of strong spin-orbit coupled magnets.

Sample growth and characterizationSingle crystals of FeTe were synthesized using a modified Bridgman method51. Stoichiometric iron (99.99%) and tellurium (99.999%) were sealed into an evacuated quartz tube and placed in a two-zone furnace. The hot (cold)-zone of the furnace was set to be 1070 (970) °C and slowly cooled down to 570 (470) °C at a rate of 2 °C/h.

SummaryBackgroundEarly diagnosis and appropriate treatment are essential in meningitis and encephalitis management. We aimed to implement and verify an artificial intelligence (AI) model for early aetiological determination of patients with encephalitis and meningitis, and identify important variables in the classification process.
