报告介绍 报告摘要：　　报告主要介绍脉冲强磁场ESR装置概况和主要技术参数、强磁场ESR的特点及其主要研究领域----单分子磁性材料和低维阻挫自旋系统。低维和三角晶格阻挫系统由于强量子涨落导致非经典效应，在低温下不再长程磁有序，而是呈现出自旋液体、激发态与基态之间具有一定的自旋能隙等异常基态，体系量子磁性的起源至今尚未完全理解。利用强磁场磁化和ESR测量可研究这类材料的异常基态、磁化平台和磁场诱导的量子相变。报告通过具体...

报告介绍 报告摘要：　　Pure spin current phenomena are the latest advances from spintronics. A pure spin current without a net charge current delivers maximal spin angular momentum using a minimal carriers, hence generating much less Joule heat in metals and no heat in insulators. A pure spin current cannot be generated by the usual means except through spin Hall effect, spin pumping, and spin Seebeck effect...

报告介绍 报告摘要：　　Recently we developed a coupled-cluster approach (CC) for closed-shell systems with SOC included in post-Hartee-Fock treatment. Total energy, analytical first and second order derivates of this SOC-CC approach at the CCSD and CCSD(T) levels have been developed. Both time-reversal symmetry and spatial symmetry for D2h and its subgroups are exploited[1] in the implementation. In addition...

报告介绍 报告摘要： 　　Broken symmetry is a fundamental concept in physics. The broken symmetries at phase transitions, such as those at the gaseous/solid and the paramagnetic/ferromagnetic transitions, are familiar examples. In cubic B20 magnets, however, it is the inversion symmetry and the 4-fold rotation symmetry that are broken. The broken inversion symmetry leads to the Dzyaloshinskii-Moriya (D-M) int...

报告介绍 报告摘要： When a tunnel barrier is in contact with resistive leads, the electromagnetic excitations in the leads provide a bosonic bath. In Nano-electronic circuits, the quantum fluctuations couple to such a bath and induce quantum dissipation effects. We first study tunneling through a resonant level connected to dissipative baths. We show that several quantum phase transitions (QPT) occur in such...

报告介绍 报告摘要： Graphite oxide sheets, now called graphene oxide (GO), are made by exfoliation of graphite using century-old chemical reactions. Interest in this old material has resurged with the rapid development of graphene since 2004, as GO is considered to be a promising precursor for bulk production of graphene. Apart from making graphene, GO itself also has many intriguing properties. For example,...

报告介绍 Abstract： The global energy supply is transforming from conventional fossil energy to sustainable energy. Sustainable energy species, for example, solar, wind, and hydro energy, are in an unsteady state and fail to provide a stable energy supply. Energy storage systems are able to collect these unsteady state energies and output as stable energy supply. Electrochemical capacitor is recognized as pr...

报告介绍 Abstract： 　　There is an ongoing drive to replace the most common transparent conductor, indium tin oxide (ITO), with a material that gives comparable performance, but can be coated from solution at speeds orders of magnitude faster than the sputtering processes used to deposit ITO. Metals nanowires are currently the only alternative to ITO that meets these requirements. This presentation wil...

报告介绍 Abstract：　　The spectacular progress in controlling the electronic properties of graphene has triggered research in alternative atomically thin two-dimensional crystals. Monolayers (ML) of transition-metal dichalcogenides such as MoS2 have emerged as very promising nanostructures for optical and electronic applications for mainly two reasons. First, the indirect bulk semiconductor MoS2 becomes dir...

报告介绍 Abstract： 　　In this talk, I will first review the progress which has been made in the past two decades for the Mott transition in single-band Hubbard model. Then I will introduce three new phenomenons existing only in multi-orbital systems, namely the orbital selective Mott transition, the Hund's metal phase and the interaction enhanced spin-orbital coupling. Two popular computational tools in th...

报告介绍 报告摘要： 　　Due to their fantastic electronic properties and promising applications, Z2=1 topological insulators have generated considerable attentions. In this talk, we study the disorder effects in various Z2=0 topological systems. In Z2=0 HgTe/CdTe quantum wells and Graphene with adatom systems, we find the random Anderson disorder (or adatom distribution) leads to a novel quantum transition: ...

报告介绍 报告摘要： 　　Since its discovery one century ago, a deep and, up to now, unresolved controversy remains on the nature of the water vapour continuum. The atmospheric science community has largely sidestepped this controversy, and has adopted a pragmatic approach: most radiative transfer codes used in climate modelling, numerical weather prediction and remote sensing are based on a semi-empirical fo...
