Visiting Professorship at the University of Barcelona: Research on Non-Perturbative Effects in Quantum Field Theories in the Presence of External Fields

该POWRE奖支持西班牙巴塞罗那大学的客座教授职位，PI将在那里开展一个研究项目，研究具有平凡和非平凡拓扑的外场存在下量子场论中的非微扰效应。预计此次访问将有助于巩固与该研究领域专家的合作，并为PI返回母校后继续开展工作提供新的见解。访问期间确定了四个不同的重点研究领域，涉及数学工具在从凝聚态物理到宇宙学等问题中的应用。该奖项由美国国家科学基金会POWRE项目、MPS理事会多学科活动办公室和物理部资助。

This POWRE award supports a Visiting Professorship at the University of Barcelona, Spain, where the PI will carry out a research project on non-perturbative effects in quantum field theories in the presence of external fields with trivial and nontrivial topology. The visit is expected to help cement a collaboration with experts in this research area and provide new insights for continuing the work once the PI has returned to her home institution. Four different areas of emphasis have been identified for study during the visit, involving application of mathematical tools to problems ranging from condensed matter physics to cosmology. The award is funded by the NSF POWRE program, the Office of Multidisciplinary Activities in the MPS Directorate, and the Physics Division.
