报告介绍 报告摘要：Simultaneously controlling magnetism and ferroelectricity is fundamentally important and bears the potential for a wide range of applications as for instance in sensorics and multiferroic memory devices with ultra low heat dissipation. A promising route to circumvent this problem is the appropriately synthesized composite ferroelectric(FE)/ferromagnetic(FM) nano and multilayer structures t...

报告介绍 报告摘要： 　　Colloidal superparticles are nanoparticle assemblies in the form of colloidal particles. Assembling nanoscopic objects into meso/macroscopic complex architectures allows bottom-up fabrication of functional materials, which is essential for many nanomaterial-based technological applications. In this seminar, we will discuss the formation of superparticles with supercrystallin...

报告介绍 报告摘要：   In the last decade, the layer-by-layer (LbL) self-assembly method, which is based on the stepwise electrostatic assembly of oppositely charged species, has emerged as a promising and versatile approach to the fabrication of functional molecular assemblies with well-defined architectures. The great advantages offered by the LbL technique are its ability to coat substrates with unifo...

报告介绍 报告摘要： 　　In this talk, I report our recent study on the magnetic and pair binding properties in newly discovered polycyclic aromatic hydrocarbon (PAH) superconductors including alkali-metal-doped picene, coronene, phenanthrene, and dibenzopentacene. We have performed a systematic numerical investigation on the possible structure of PAH as functions of pressure and doing. Correlation effects we...

报告介绍 报告摘要：　　High-resolution molecular spectroscopy provides us with the most detailed information of the structure and properties of molecules. In this seminar, I will give a brief introduction to high-resolution molecular spectroscopy and then focus on one of the molecules that I have been studying, the methoxy radical (CH3O). In CH3O, spin and orbital angular momenta of electrons and vibrational...

报告介绍 Abstract:      　　The role of disorder in the formation of two-dimensional networks is currently attracting great interest and provides interesting connections between surface science and statistical mechanics. The properties of an entropy-stabilised supramolecular network will be reviewed. These networks map directly onto a rhombus tiling of the plane and support a random ...

报告介绍 报告摘要：Superconducting quantum qubit and resonator are representative solid state quantum devices, which is also a good quantum system to simulate quantum phenomena in different fields such as quantum optics. A superconducting resonator with controlled mirror transparency was developed, leading to a variable coupling to the outside transmission line. The coupling can be adjusted through zero to a...

报告介绍 Abstract：Electron spin dephasing dynamics in ferromagnetic (Ga,Mn)As with Mn concentration x spanning the wide range from 0.5% to 15% across the insulator-to-metal transition, is systematically studied by varying temperature and optical pumping density with time-resolved magneto-optical Kerr effect measurements (TR-MOKE). For (Ga,Mn)As with different Mn doping concentration, the electron spin depha...

报告介绍 报告摘要： To understand in vitro protein folding/unfolding at various physical conditions is important for gaining insights on connections among protein structure, dynamics and biological function in the molecular biophysics field. This talk discusses molecular dynamics simulations on two di-domain proteins, crystallin and survivin, in order to explore the relationship between folding and domain-do...

报告介绍 报告摘要：　　本报告讨论分子表面界面的非线性光学振动光谱和动力学研究中的定量测量和分析中的近期进展。二十多年来，频率和时间分辨的界面和频振动光谱（SFG-VS）被用于选择性地检测分子表面和界面的结构与动力学性质。发挥SFG-VS方法的潜力关键是依赖于在频域和时域的SFG的定量测量能力。最近我们首次发展了亚波数分辨率的高分辨宽带和频振动光谱（HR-BB-SFG-VS）技术，其光谱高分辨率达到～0.6波数，而且时间分辨率优于100飞秒...

报告介绍 Abstract：　　A fundamental materials challenge is to form structure that is not frozen in place but instead reconfigures internally driven by energy throughput and adapts to its environment robustly. Predicated on fluorescence imaging at the single-particle level, this talk describes quantitative studies of how this can happen. With Janus colloidal clusters, we show the powerful role of synchronize...
