大会报告1：
报告题目：广义相对论，黑洞和引力波
报 告 人：蔡荣根 院士
工作单位：中国科学院理论物理研究所
内容提要：
2016年2月11日美国LIGO科学团队宣布人类第一次直接探测到了引力波。这次引力波事件的波源是二个黑洞的并合事件。引力波的直接探测证实了爱因斯坦100年前基于广义相对论的预言，开启了引力波天文学的新时代。该报告将介绍广义相对论，其二大预言黑洞和引力波及其相关的物理意义。

Exploring the Intrinsic Features of Ideal Glass From Computation

The nature of glass states has been the long-standing problem in the solid-state physics. With the state-of-art of computational tools locally developed in Fudan, we performed intensive simulations on the thermodynamic properties and explored potential energy surface of an ideal glass which was identified in our own group. We found that the atoms of an ideal glass manifest cooperative diffusion, and show clearly different behavior from the liquid state. By determining the potential energy surface, we demonstrated that the glass state has a flat potential landscape, which is the intrinsic feature of ideal glass. Through manipulating the potential surface, we obtained strong evidence that disordering is not the intrinsic properties of glass, although most of the glasses we know are disorder. With this picture, we could provide some interpretation on the glass transition.

There are several projects in either the preparatory phase or the implementation phase for delivering 10PW laser pulses in the world. We will report the progress of 10PW Shanghai Superintense Ultrafast Laser Facility (SULF) and present a new method that uses a temporal dual-pulse pump beam to suppress the parasitic lasing in large aperture Ti:sapphire crystals. In 2016, the output signal energy of 202.8 J from a 150mm size Ti:S amplifier was obtained, with a signal to pump conversion efficiency of 49.3%. The chirped pulse was compressed by a grating compressor down to 24.0 fs, leading to the output of 5PW laser pulses. In 2017, a similar technology was successfully used to implement the 235mm in diameter Ti:sapphire amplifier which can output 339J chirped pulse. A small part of the laser energy was compressed down to 21fs, indicating that a 10.3PW pulse can be produced if the full energy pulse can be compressed by using large enough gratings. According to the schedule, the 10PW laser facility will be ready in the beginning of 2019 and then opened to users.
More recently, we have launched the project of Station of Extreme Light (SEL) under the Shanghai Coherent Light Facility (SCLF) at Shanghai. SCLF is a super conducting XFEL facility. As one of stations of SCLF, SEL will be equipped a 100PW laser system. SEL attempts to make use of the two kinds of most intense lasers, i.e. the 100PW optical laser and the TW level hard x-ray laser. The combination of the hard XFEL and the 100PW laser will initiate exploration of vacuum birefringence, acceleration mechanisms leading to ultra-high energy cosmic rays, and so on. The 100 PW laser system will be based on the optical parametric chirped-pulse amplification (OPCPA) approach to realize 1500J/15fs output, with a designed intensity of higher than 1023 W/cm2. According to the plan, the 100PW laser will be available in 2024.
