This award is made as part of the FY 2021 Mathematical and Physical Sciences Ascending Postdoctoral Research Fellowships (MPS-Ascend). Each fellowship supports a research and training project at a host institution in the mathematical and physical sciences, including applications to other disciplines, under the mentorship of a sponsoring scientist. This fellowship to Dr. Joshua Sanchez supports his research project entitled "Probing electronic symmetry breaking in strain-tuned quantum matter." The host institution for the fellowship is the Massachusetts Institute of Technology, and the sponsoring scientist is Dr. Riccardo Comin.Dr. Sanchez's research focuses on mechanical strain tuning in quantum materials to investigate electronic symmetry breaking in quantum matter characterized by strong coupling of charge and lattice degrees of freedom. The fellow plans to broaden participation at local majority-minority community colleges through hosting lab tours at MIT and leading graduate-school application-writing workshops. In mentoring undergraduates, Dr. Sanchez will create travel opportunities for the students to large-scale x-ray facilities where they will perform first-hand x-ray measurements. With regards to outreach to the broader community Dr. Sanchez will work with the American Physical Society to make important cultural changes to create a more fostering environment for diverse students nationally.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.

该奖项是 2021 财年数学和物理科学提升博士后研究奖学金 (MPS-Ascend) 的一部分。每项奖学金都支持主办机构在数学和物理科学方面的研究和培训项目，包括在资助科学家的指导下在其他学科的应用。约书亚·桑切斯博士的这项奖学金支持他的研究项目，题为“探测应变调谐量子物质中的电子对称性破缺”。该奖学金的主办机构是麻省理工学院，资助科学家是 Riccardo Comin 博士。桑切斯的研究重点是量子材料中的机械应变调谐，以研究量子物质中以电荷和晶格自由度强耦合为特征的电子对称性破缺。该研究员计划通过在麻省理工学院举办实验室参观和领导研究生院申请写作研讨会来扩大对当地少数族裔社区大学的参与。在指导本科生时，桑切斯博士将为学生创造前往大型 X 射线设施的机会，在那里他们将进行第一手 X 射线测量。在向更广泛的社区推广方面，桑切斯博士将与美国物理学会合作，进行重要的文化变革，为全国多样化的学生创造一个更有利于培养的环境。该奖项反映了 NSF 的法定使命，并通过使用评估方法进行评估，认为值得支持。基金会的智力价值和更广泛的影响审查标准。
