4Quantum corrections to the classical Newtonian interactions

報告人：余洪偉，湖南師范大學

時間：10月19日（周三）10:00

單位：北京師范大學物理學系

地點：物理樓106

When gravity is quantized, there inevitably exist quantum gravitational vacuum fluctuations which induce quadrupole moments in gravitationally polarizable objects and produce, in close analogy to the Casimir-Polder forces, quantum corrections to the classical Newtonian interactions such as those between polarizable objects, and a polarizable object and a boundary. In this talk, we review our recent calculations of these forces.

6自旋玻璃：理論方法及網絡科學應用

報告人：周海軍，中科院理論物理所

單位：北京師范大學物理學系

地點：物理樓106

自旋玻璃是1975年由 Edwards 和 Anderson 提出來的用于理解無序和阻挫的磁性材料的一個簡單模型。經過四十年的研究發展，自旋玻璃研究已然成為統計物理學的一個重要研究方向，并推動了統計物理學在約束滿足、組合優化、統計推斷、網絡科學等方面的交叉學科應用；但國內從事自旋玻璃理論研究的團隊很少。在這一報告中，我將介紹自旋玻璃平均場理論的關鍵物理思想和基于消息傳遞的分布式計算方案，并介紹這些理論方法在隨機 K－滿足問題、最小反饋節點集合問題、復雜網絡最優攻擊問題上的成功應用。

7China and the Future of Fundamental Physics

報告人：Nima Arkani-Hamed，IAS, Princeton

時間： 10月19日（周三）18:30

單位：中國科學院理論物理研究所

地點：新樓6620

Nima Arkani-Hamed is one of the leading theoretical physicist of his generation with broad interests in high-energy physics, string theory and cosmology. He has taken a lead in proposing new physical theories that can be tested at the Large Hadron Collider at CERN. His research has shown how the extreme weakness of gravity might be explained by the existence of extra dimensions of space, and his recent work focuses on a reformulation of the foundations of quantum field theory. He is a professor at the prestigious Institute for Advanced Study in Princeton, and the inaugural director of the Center for Future High Energy Physics in China. He has received numerous awards, including the Fundamental Physics Prize in 2012.

8Integral reduction at multi loop, an algebraic geometry story

報告人：Yang Zhang，ETH, Zurich

時間： 10月20日（周四）10:00

單位：中科院高能物理研究所

地點：Conference Hall 319, Theoretical Physics Division

Multiloop amplitude is very important for the study of LHC physics. Given large number of Feynman diagrams, we need to consider the reduction to a small number of master integrals. Usually this is achieved by IBP relations, however, IBP computation is often very heavy. In this talk, we show the recent progress of IBP reduction, based on generalized unitarity and new mathematical method: computational algebraic geometry.

In his talk, I will show ur experimental realizations and theoretical predictions of 2D and 3D photonic crystals with topologically protected edge and surface sates.Specifically,I will discuss single and multimode one-way aveguides,the observation of Weyl points,and a nonsymmorphic 3D photonic crystal supporting a single Dirac cone surface tate immune to random disorder.This research can be xtended to phonons,plasmons and other bosons.These new degrees of freedom in bosonic band topologies promise wide exciting opportunities in both fundamental physics and technological outcomes.

10A Good Hard Look at Growing Supermassive Black Holes in the Distant Universe

報告人：Niel Brandt，Penn State U

時間： 10月20日（周四）16:00

單位：北京大學科維理天文與天體物理研究所

地點：KIAA-PKU Auditorium

Sensitive cosmic X-ray surveys with the Chandra, XMM-Newton, and NuSTAR observatories have revolutionized our ability to find and study distant active galactic nuclei (AGNs), the main sites of supermassive black hole growth in the Universe. I will describe some of the resulting discoveries about the demographics, physics, and ecology of AGNs. Topics covered will include the utility of deep X-ray plus multiwavelength surveys for investigating distant AGNs; evolution constraints for the typical AGNs of the distant Universe; the cosmic balance of power between supermassive black holes and stars; interactions between AGNs and their hosting galaxies; and the AGN content of newly forming galaxies. I will end by discussing some key outstanding questions and new observations and missions that aim to answer them.

11All-Optical Helicity-Dependent switching in magnetic nano-structures and devices

報告人：S. Mangin，Institut Jean Lamour

時間： 10月21日（周五）09:00

單位：清華大學物理系

地點：理科樓C302報告廳

It is within that context that we are studying the effect of femtosecond laser pulses on magneto-resistive systems with perpendicular magnetic anisotropy, with the aim of identifying the magnetization orientation through an electrical signal. We measure the all-optical switching in Pt/Co/Pt and Tb27Co73 based Hall crosses via the anomalous Hall effect. In fact, a jump in Hall voltage resulting from magnetization reversal is observed by reversing the circular polarization of the femtosecond laser pulses. This new way of probing the all-optical switching enables a statistical quantification of the switching ratio for different laser parameters. We will present results on hall crosses for both ferrimagnetic and ferromagnetic materials.

12Progress on continuous-time dynamic cavity method

報告人：Erik Aurell，Royal Institute of Technology KTH

時間： 10月21日（周五）10:30

單位：中科院理論物理研究所

地點：Room 6420, ITP new building

Computing the marginal probabilities of a Gibbs-Boltzmann probability distribution has many applications in Physics and outside Physics. Efficient approximate methods have been developed over several decades to achieve this task if the graph of interactions has a locally tree-like form, as it has for random graphs. In Physics these methods are called the cavity method or the Bethe-Peierls method; in computer science they are called Belief Propagation and in Information Theory they are a part of iterative decoding.
