This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).This award is for state-of-the-art spectroscopic instrumentation for the Departments of Physics and Chemistry and Biochemistry at California State University - East Bay for research in the fields of atomic physics, condensed matter physics, material science, and physical chemistry. The interdisciplinary team of scientists, all experienced spectroscopists and active researcher-educators will carry out a wide array of spectroscopic research projects. In atomic physics, direct frequency comb spectroscopy will be employed in a long-term research program to understand the complex spectra of rare-earth atoms, enabling discovery of a large number of theoretically predicted energy levels yet to be experimentally found and determination of atomic state parameters (such as lifetimes, polarizabilities, hyperfine splittings, gyromagnetic ratios, etc.) that have never been measured. These experiments will vastly improve our knowledge of rare-earth atoms and allow evaluation of potential candidates among metastable states in rare-earth atoms for new tests of fundamental physics, in particular searches for the permanent electric dipole moment of the electron. In condensed matter physics, characteristic low energy excitations will be probed in correlated electronic systems and temperature-frequency scaling behavior will be tested in systems that undergo quantum phase transitions. In materials science, THz spectroscopy will facilitate the characterization of novel thin film photovoltaic systems as well as engineered metamaterials split ring resonator structures (so-called negative index of refraction materials). Finally in physical chemistry the system will be used to create composite spectra for atmospherically relevant greenhouse gases and molecules.The research on spectroscopy of atoms, molecules and condensed matter systems blends the power of the new systems with well-developed experimental methods and analysis techniques - well-suited for undergraduate research - used both in academic and industrial research. The acquisitions will provide students in multiple disciplines (physics, chemistry, and biochemistry) access to experiences and research opportunities they otherwise would not have. In particular, California State University - East Bay is one of the most diverse undergraduate institutions in the U.S. (in 2008, the student diversity ranked 67th out of 2,474 four-year universities according to the U.S. Department of Education), and our departments are at the forefront of recruitment and retention of underrepresented minorities and women in the physical sciences. At an affordable, accessible, public university, this Major Research Instrumentation acquisition will provide opportunities to the broadest possible range of students and attract new physical science majors from the extremely diverse pool of students attending California State University East Bay.

该奖项是根据2009年的《美国复苏与再投资法》（公法111-5）资助的。该奖项是为加利福尼亚州立大学物理，化学和化学和生物化学部门的最先进的构图仪器，用于原子质物理学，材料，物质科学和物理化学的培养基。科学家，经验丰富的谱学家和活跃的研究人员的跨学科团队将进行各种光谱研究项目。在原子物理学中，将在一项长期研究计划中采用直接频率梳光谱法来了解稀土原子的复杂光谱，从而发现大量理论上预测的能量水平尚未实验发现并确定原子态参数（如生命时代，极限，超级精力，gyromagios，gyromagios，gyromagios et eft youse con。这些实验将极大地提高我们对稀土原子的了解，并允许评估稀土原子中亚稳态状态之间的潜在候选物，以进行新的基本物理测试，特别是寻找电子的永久性电偶极矩。在冷凝物理物理学中，将在相关的电子系统中探测特征性低能激发，并且将在经历量子相变的系统中测试温度频率缩放行为。在材料科学中，THZ光谱法将促进新型薄膜光伏系统以及工程的超材料拆分环谐振器结构的表征（所谓的折射材料的负面指数）。最后，在物理化学中，该系统将用于为与大气相关的温室气体和分子创建复合光谱。关于原子，分子和冷凝物系统光谱的研究，将新系统的功能与开发良好的实验方法和分析技术融为一体 - 用于学术研究和工业研究的不足。这些收购将为学生提供多个学科（物理，化学和生物化学）的访问权限，以获得他们原本没有的经验和研究机会。尤其是加利福尼亚州立大学 - 东湾是美国最多样化的本科机构之一（根据美国教育部的说法，在2,474个四年制大学中，学生多样性在2,474个四年制大学中排名第67），我们的部门处于招聘的前提下，在物理学上的招聘和保留不足。在一所负担得起的公立大学，这项主要的研究工具获取将为最广泛的学生提供机会，并吸引来自加利福尼亚州立大学东湾的非常多样化的学生群的新物理科学专业。
