Photoemission from the gas phase using soft x-ray fs pulses: An investigation of the space-charge effects
Adriano Verna, Giovanni Stefani, Francesco Offi +13
An experimental and computational investigation of the space-charge effects occurring in ultrafast photoelectron spectroscopy from the gas phase is presented. The target sample CF$…
Microscopic Theory of Quadrupole Ordering in Pr Compounds on the Basis of a - Coupling Scheme
Ryosuke Yamamura, Takashi Hotta
Toward the understanding of incommensurate quadrupole ordering in PrPb, we develop a microscopic theory of multipole ordering in -electron systems from an itinerant…
Valence Imbalance of Manganese Ions between Surface and Bulk Enhanced by Fermi-Surface Structure in Layered Manganites
Ryosuke Yamamura, Takashi Hotta
To investigate valence imbalance phenomena between the surface and bulk in layered manganites, we analyze an eg-orbital degenerate double-exchange model with surfaces for two types…
Quantum Interference of Surface-Induced Friedel Oscillations Enhanced by Fermi-Surface Nesting in Layered Manganites
Ryosuke Yamamura, Takashi Hotta
Imbalance of Mn3+ and Mn4+ ions between surface and bulk in layered manganites is investigated on the basis of an orbital degenerate double-exchange model with surfaces. For two ty…
Multipole ordering in f-electron systems on the basis of a j-j coupling scheme
Katsunori Kubo, Takashi Hotta
We investigate microscopic aspects of multipole ordering in f-electron systems with emphasis on the effect of lattice structure. For the purpose, first we construct f-electron mode…
