Venue: Lecture Hall, 1st floor, Run Run Shaw Science Building, Yuquan CampusSpeaker:Wei Fan joined Nature Communications in September 2015. He obtained his PhD in Condensed Matter Physics from the Chinese Academy of Science, collaborating with the University of Bremen, City University of Hong Kong and Duke University. He then moved to RIKEN in Japan for postdoctoral research. His research background is in electronic and magnetic properties of semiconductors, multiferroic oxides and phase transitions of strongly correlated materials. Wei handles manuscripts on topological matter and superconductivity. He is based in the Shanghai office.Abstract: In this talk, I would like to introduce the Nature family journals and describe the key differences between different journals. I will briefly talk about the scope, content type, and editorial requirements for Nature, Nature Research Journals, Nature Reviews Journals and Nature Communications. Following a brief introduction of my colleagues, I would like to talk about details of editorial processes and how editors make decisions at various stages from pre-submission to post-peer review. Lastly, I would like to talk about open access journals and recent policies trialed in Nature Communications.

Raman scattering is an inelastic scattering of light. Raman spectroscopy is frequently observed for characterizing the structure of emerging two-dimensional materials such as graphene, transition metal dichalcogenides. When we change the laser excitation energy for observing the Raman spectra, the Raman intensity significantly changes due to the resonant Raman effect. Combining with our original computer program for resonant Raman intensity, we can understand many properties from Raman spectra of the recent two-dimensional materials. In particular, when we use circularly polarized light, we get some special Raman spectra appears in which the inelastic scattered light has an opposite helicity of the circularly polarized light to that of the incident light, which we can explain by the symmetry analysis. Here we will discuss on conservation law of angular momentum of a photon in the Raman processes. When we discuss optical properties of two-dimensional materials, the concepts of valley polarization and circular dichroism are important, which we will discuss possible phenomena that occur in two-dimensional materials. Short biographyRiichiro Saito was born in 1958, and received his Ph.
