Physics Building (6F) Room 620 | | 近十年來,量子多體計算方法歷經快速演進:張量網路方法(DMRG、TRG、PEPS 等)已從一維系統推展至二維與無限系統;量子蒙特卡羅方法持續發展新的更新演算法以緩解符號問題;機器學習與生成式AI 技術則為波函數表示、相變偵測、資料驅動之量子態層析開啟了全新途徑。這些方法的進展,直接決定了我們理解挫折磁性、量子自旋液體、拓撲物質、強關聯超導等前沿問題的能力上限。本論壇邀集橫跨張量網路、量子蒙特卡羅、機器學習等不同數值方法陣營的學者,一方面呈現各方法最新的技術突破,另一方面促成跨方法之間的交流與方法論比較,對於推動台灣在計算附件一凝態物理領域與國際接軌、培育具備現代數值方法能力之新一代研究人才,深具意義。 |

Wing-Huen Ip (Graduate Institute of Astronomy, National Central University) | Laboratory studies of astrochemistry in star forming regions, the interstellar medium, and Solar System materials have been on the rise to the forefront of cross-disciplinary research in Astronomy and Astrophysics. They lie at the crossroads and involve innovative applications of the many cutting-edge instruments developed for traditional areas of physics: condensed matter, atomic and molecular, surface, material, accelerators, photonics, and so on. On the other hand, the traditional study of meteorites and solar system materials has utilized a different set of platforms and methodologies. In this topical symposium, we aim to raise community awareness of cross-pollination among the diverse disciplines of the physical sciences and the field's future impact.
Synchrotron radiation is a powerful tool in laboratory studies of a number of important topics in astronomy and planetary science ranging from the hot chemistry in interstellar icy grains that might be associated with the formation of complex organic molecules to isotopic fractionation. Furthermore, the X-ray sources are indispensable in probing the three dimensional structures of the nano-sized grains in meteorites and dust samples collected from the Moon and asteroids.
In this session, the results from research projects carried out at the National Synchrotron Radiation Research Center will be summarized with a view to assess how a pioneering interdisciplinary program in laboratory astrobiology and astrochemistry essential to the understanding of origin of the solar system and the production of prebiotic materials (i.e. tholins) in the atmosphere of Titan and comets might be established by linking the NSSRC facility with advanced instruments, Raman, TEM, SEM, EDS, EPMA, TEM, and NanoSIM. |
