Soft-mode driven polarity reversal in ferroelectrics mapped by ultrafast x-ray diffraction
Quantum theory has linked microscopic currents and macroscopic polarizations of ferroelectrics, but the interplay of lattice excitations and charge dynamics on atomic length and time scales is an open problem. Upon phonon excitation in the prototypical ferroelectric ammonium sulfate [(NH(4))(2)SO(4)...
