Photoinduced Nonequilibrium Dynamics in Charge Ordered Materials
Linghua Zhu, Tsezar F. Seman, Michel van Veenendaal +1
We study the nonequilibrium dynamics of photoinduced phase transitions in charge ordered (CO) systems with a strong electron-lattice interaction and analyze the interplay between e…
The many faces of quantum kagome materials: Interplay of further-neighbour exchange and Dzyaloshinskii-Moriya interaction
Tsezar F. Seman, Cheng-Chien Chen, Rajiv R. P. Singh +1
The field of frustrated magnetism has been enriched significantly by the discovery of various kagome lattice compounds. These materials exhibit a great variety of macroscopic behav…
Momentum dependence in K-edge resonant inelastic x-ray scattering and its application to screening dynamics in CE-phase LaSrMnO
T. F. Seman, X. Liu, J. P. Hill +2
We present a formula for the calculation of K-edge resonant inelastic x-ray scattering on transition metal compounds, based on a local interaction between the valence shell electro…
Strongly momentum-dependent screening dynamics in LaSrMnO observed with resonant inelastic x-ray scattering
X. Liu, T. F. Seman, K. H. Ahn +6
We report strongly momentum-dependent local charge screening dynamics in CE-type charge, orbital, and spin ordered LaSrMnO, based on Mn K-edge resonant inelasti…
Strain-induced metal-insulator phase coexistence and stability in perovskite manganites
T. F. Seman, K. H. Ahn, T. Lookman +1
We present a detailed study of a model for strain-induced metal-insulator phase coexistence in perovskite manganites. Both nanoscale and mesoscale inhomogeneities are self-consiste…
Effects of rare earth ion size on the stability of the coherent Jahn-Teller distortions in undoped perovskite manganites
T. F. Seman, K. H. Ahn, T. Lookman +3
We present a theoretical study on the relation between the size of the rare earth ions, often known as chemical pressure, and the stability of the coherent Jahn-Teller distortions…
Symmetry-mode-based classical and quantum mechanical formalism of lattice dynamics
Tsezar F. Seman, Jichan Moon, K. H. Ahn
We present classical and quantum mechanical descriptions of lattice dynamics, from the atomic to the continuum scale, using atomic scale symmetry modes and their constraint equatio…
