Experimental Search for Quantum Gravity VI

量子引力是广义相对论和量子力学的结合，对它的探索已经进行了80年，除非我们有一个完整的、经过实验验证的理论，否则它永远不会结束。虽然对量子引力的直接、详细的测试目前还遥不可及，但已经有许多关于实验测试的建议，这些实验测试间接地揭示了一个或另一个量子引力模型。其中许多建议依赖于重新利用最初为其他科学努力开发的技术和技术。量子引力实验搜索会议提供了关键的跨学科环境，使量子引力以外的专业实验家和量子引力理论家可以讨论并取得进展，既改进现有的量子引力相关物理实验测试，又创造新的实验测试。2020年的会议将于春夏季在新罕布什尔大学举行，为期一周。它将吸引40-60名教职员工和博士后，会议将涉及(1)宇宙学中的量子引力特征，(2)量子引力方面的前瞻性实验室测试，(3)凝聚态系统中的模拟引力和霍金辐射，(4)强场观测，包括黑洞-黑洞和黑洞-中子星合并和视界尺度测量，以及相应的黑洞热力学和量子引力约束激发的修正引力理论；(5)时空对称性的检验。有两场公开演讲：一场是关于量子引力提出的理论和哲学问题，另一场是关于用于测试引力物理的实验工具。会议演讲和幻灯片将在会议结束后的三年内被录制、收集并发布到网上。会议将把来自不同理论和实验领域的研究人员联系起来，促进在量子引力测试中综合现有技术、多信使天文学和量子信息方法方面的工作，并培训年轻的科学家和学生掌握各种最先进的方法。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

The search for quantum gravity, the merger of general relativity and quantum mechanics, has been ongoing for eight decades and will never be finished until we have a complete and experimentally verified theory. While direct, detailed tests of quantum gravity are currently out of reach, there have been numerous proposals for experimental tests that indirectly shed light on one quantum gravity model or another. Many of these proposals rely on re-purposing technology and techniques originally developed for other scientific endeavors. The Experimental Search for Quantum Gravity meetings provide the critical cross-disciplinary environment so that experimentalists with expertise outside quantum gravity and quantum gravity theoreticians can discuss and make progress on both improving existing experimental tests of quantum gravity related physics and creating new ones.The meeting for 2020 will be held at the University of New Hampshire for one week in spring/summer. It will draw between 40-60 faculty and postdocs and have sessions on (1) quantum gravity signatures in cosmology, (2) prospective laboratory tests of aspects of quantum gravity, (3) analog gravity and Hawking radiation in condensed matter systems, (4) strong field observations, including those of black hole-black hole and black hole-neutron star mergers and horizon scale measurements, and corresponding constraints on black hole thermodynamics and quantum gravity motivated modified gravitational theories, and (5) tests of spacetime symmetries. There will two public talks: one on the theoretical and philosophical problems presented by quantum gravity, and one on the experimental tools used to test gravitational physics. Meeting talks and slides will be recorded, collected, and posted online for a period of three years after the meeting. The meeting will connect researchers from disparate theoretical and experimental fields, stimulating work on synthesizing existing techniques, multi-messenger astronomy, and quantum information approaches in quantum gravitational tests, and train younger scientists and students in the varied state of the art approaches.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
