Calculated Momentum Dependence of Zhang-Rice States in Transition Metal Oxides

Using a combination of local density functional theory and cluster exact diagonalization based dynamical mean field theory, we calculate many body electronic structures of several Mott insulating oxides including undoped high T_{c} materials. The dispersions of the lowest occupied electronic states are associated with the Zhang-Rice singlets in cuprates and with doublets, triplets, quadruplets and quintets in more general cases. Our results agree with angle resolved photoemission experiments including the decrease of the spectral weight of the Zhang--Rice band as it approaches k=0

Transculturating the modern : Zhang Ruogu\u27s literary life in 1930s Shanghai

Zhang Ruogu 張若谷(1905-1967), now known primarily as an urban writer,2 began his literary career by translating and commenting on French literature in newspapers and journals and subsequently published several urban stories. He was also an active advocate of urban life and played an important role in the introduction of the ideas of the French-style café gathering and European cultural trends. Zhang Ruogu’s literary activities, his admiration of French literature and culture, and his works inspired by the French literary works that he admired or translated, are the focus of investigation of this paper. From Paris to Shanghai and from 19th-century French literature to urban stories of Shanghai of the 1930s, these literary trends and works advanced through a process of translation and interpretation. What occurred during this translation and interpretation process? How does this examination aid us in understanding Zhang Ruogu’s own work and modern Chinese literature? This paper addresses Zhang Ruogu’s translations, adaptations and interpretations of French literature as well as his own literary works

Multiwavelength analysis as a probe of accretion and radiative processes in LINERs

We study the multiwavelength properties of an optically selected sample of Low Ionization Nuclear Emission-line Regions (LINERs), in an attempt to determine the accretion mechanism powering their central engine. We show how their X-ray spectral characteristics, and their spectral energy distribution compare to luminous AGN, and briefly discuss their connection to their less massive counter-parts galactic black-hole X-ray binaries.Comment: 2 Pages.
