THz-induced phonon mode mixing and collective dynamics in a polar nanolattice
Elizabeth Skoropata, Peter M. Derlet, Hiroki Ueda +13
Manipulating phonons through symmetry is a fundamental approach to alter the dynamic responses of materials. Most often new phases are sought through control of the unit-cell (e.g.…
Anharmonic phonon coupling enabled by local inversion symmetry breaking at domain walls in ferroelastics
Seyyed Jabbar Mousavi, Vivek Unikandanunni, Niccolo Sellati +7
In ferroelastic materials, spontaneous symmetry breaking leads to the formation of twin domains. Although the bulk crystal typically remains centrosymmetric, inversion symmetry can…
Real-time manifestation of strongly coupled spin and charge order parameters in stripe-ordered nickelates via time-resolved resonant x-ray diffraction
Y. D. Chuang, W. S. Lee, Y. F. Kung +27
We investigate the order parameter dynamics of the stripe-ordered nickelate, LaSrNiO, using time-resolved resonant X-ray diffraction. In spite of distinct spi…
Phase Fluctuations and the Absence of Topological Defects in Photo-excited Charge Ordered Nickelate
W. S. Lee, Y. D. Chuang, R. G. Moore +32
The dynamics of an order parameter's amplitude and phase determines the collective behaviour of novel states emerged in complex materials. Time- and momentum-resolved pump-probe sp…
Femtosecond dynamics of the collinear-to-spiral antiferromagnetic phase transition in CuO
S. L. Johnson, R. A. de Souza, U. Staub +22
We report on the ultrafast dynamics of magnetic order in a single crystal of CuO at a temperature of 207 K in response to strong optical excitation using femtosecond resonant x-ray…
