报告题目：Quantum Aspects of Black Holes

报告人：Prof. Hossein Yavar

工作单位：Institute of Theoretical Physics, CAS

摘要：Black holes are the most fascinatingobjects in our universe. The attempt to understand them in quantum mechanicsleads to several fundamental puzzles. Solution to these puzzles is probably thebest clue to puzzle out quantum gravity. One may consider the present status ofblack hole in quantum gravity as the state of blackbody in the beginning of thelast century and discovering quantum mechanics. In this talk, I will brieflyreview some of these puzzles and the recent approaches to answering them.

报告题目：Polarization in the GRB Jet Emission

摘要：Gamma-ray bursts (GRBs) are the mostviolent explosions in the universe. Literally, two kinds of central engines(CEs) are involved. One is black hole + accretion disk system, the other is millisecondmagnetar. The information got from the traditional light curves and spectrum islimited. Study of the polarization opens a new window. In this talk, I willfirst give a brief introduction to the polarization. Then I will talk about 1)polarization in distinguishing the GRB CEs, 2) polarization in distinguishingthe different models of GRB X-ray shallow decay phase, 3) polarization with a3-dimensional mixed magnetic field, 4) polarization with a precessing jet.
