The mission of the physics program is to give in-depth training in physics to our majors and minors through a student-centered program based on rigorous coursework and research opportunities. The physics curriculum challenges our students to solve problems, think critically, develop experimental and computational skills, and hone their written and verbal communication skills. The physics faculty are committed to professional activities that make noteworthy contributions to the greater scientific community, including at the national and international levels. With expertise in their respective disciplines, the faculty engage students in high-impact research experiences and mentor them as future scientists. The program also vigorously supports students in obtaining external internship and research opportunities and preparing them for careers in industry, government, teaching, or post-graduate work in various subfields of physics and engineering. Physics faculty further contribute to the educational goals of the College by providing direct support of other major programs such as biochemistry & molecular biology, biology, chemistry, exercise science, interaction design, and physical therapy. In addition, physics faculty teach Formative and Connective courses in the Constellation program that cultivate math and science literacy, quantitative reasoning, problem solving, and critical analysis of information and data. Through its students, faculty, and extracurricular activities, the physics program strives to contribute to the academic and cultural environment of the College, and academic community, by providing opportunities and expertise in physics within a liberal arts environment.

Nature Physics publishes papers of the highest quality and significance in all areas of physics, pure and applied. The journal content reflects core physics disciplines, but is also open to a broad range of topics whose central theme falls within the bounds of physics.
Nature Physics is committed to publishing top-tier original research in physics through a fair and rigorous review process. It offers readers and authors high visibility, access to a broad readership, high standards of copy editing and production, rapid publication, and independence from academic societies and other vested interests.
The journal features one paper format for primary research: the Article. (Please see this recent editorial for an explanation of why.) In addition to publishing primary research, Nature Physics serves as a central source for top-quality information for the physics community through Review Articles, News & Views, Research Highlights on important developments published throughout the physics literature, Commentaries, Book Reviews, and Correspondence.
I can not find out the right conjugation relation for an oil immersion objective (oil in the object space, air in the image space).If I send an incident plane wave in air with angle $\alpha_air$ with regard to the optical axis, its angle in oil $\alpha_oil$ will be smaller because of refraction.Where will focus the plane wave in the rear focal plane of an oil immersion objective with focal $f$ ? At the coordinate $f \tan(\alpha_air)$ or $f \tan(\alpha_oil)$ ? The question is illustrated in the image below.
Edit : The first intuition is that the ray passing through the lens is not deviated. However, this is incompatible with Abbe sine relation, as shown in the picture below. Abbe sine relation should be verified by an aplanetic objective (that is not at a thin lens).
Researchers in Switzerland have built what they claim is the simplest microscope objective ever constructed. The device, which comprises just two optical components, is based on the classic Schmidt telescope design and works in a variety of immersion liquids as well as air. Because the new objective has a larger field of view and working distance than standard devices, the researchers say it could be used to image large organs and even whole organisms.
For the last century and a half, Voigt points out, most microscope objectives used in bio-imaging have been built with lenses. Mirror-based designs have largely been neglected, but they do have one great advantage: unlike conventional lens-based objectives, their behaviour does not depend on refractive index. This means that mirrors can be used to make so-called multi-immersion objectives that can produce a sharp image when immersed in many different liquids.
The new objective, which the team call a Schmidt objective, has a high numerical aperture of 1.08 at a refractive index of 1.56, a field of view of 1.1 mm and a working distance of up to 11 mm. This combination of properties is rare in microscope objectives since devices with a high numerical aperture often lack the working distance required to reach features of interest deep inside a sample. This is especially true for cleared samples, which in recent years have increased significantly in size, to the extent that entire mouse bodies and whole human organs can now be cleared.
And at least one specialty area of application in the field of Physics as offered by the Department such as: Optics, Solid State Physics, Ocean Physics, Astrophysics, Traffic Physics, Relativity & Cosmology, Computational Physics, Fluid Mechanics, Nuclear Physics, Atomic Physics, and Physics Education.
Modeling and simulation of complex non-linear systems are essential in physics, engineering, and signal processing. Neural networks are widely regarded for such tasks due to their ability to learn complex representations from data. Training deep neural networks traditionally requires large amounts of data, which may not always be readily available for such systems. Contrarily, there is a large amount of domain knowledge in the form of mathematical models for the physics/behavior of such systems. A new class of neural networks called Physics-Informed Neural Networks (PINNs) has gained much attention recently as a paradigm for combining physics into neural networks. They have become a powerful tool for solving forward and inverse problems involving differential equations. A general framework of a PINN consists of a multi-layer perceptron that learns the solution of the partial differential equation (PDE) along with its boundary/initial conditions by minimizing a multi-objective loss function. This is formed by the sum of individual loss terms that penalize the output at different collocation points based on the differential equation and initial and boundary conditions. However, multiple loss terms arising from PDE residual and boundary conditions in PINNs pose a challenge in optimizing the overall loss function. This often leads to training failures and inaccurate results. We propose advanced gradient statistics-based weighting schemes for PINNs to address this challenge. These schemes utilize backpropagated gradient statistics of individual loss terms to appropriately scale and assign weights to each term, ensuring balanced training and meaningful solutions. In addition to the existing gradient statistics-based weighting schemes, we introduce kurtosis-standard deviation-based and combined mean and standard deviation-based schemes for approximating solutions of PDEs using PINNs. We provide a qualitative and quantitative comparison of these weighting schemes on 2D Poisson's and Klein-Gordon's equations, highlighting their effectiveness in improving PINN performance.

The role played by objectivity in continuum physics is reexamined in an attempt to establish fully its deep connection with classical and relativistic time derivatives. The way of distinguishing one element in the class of objective time derivatives may depend on the particular problem of interest; this is emphasized in conjunction with material relaxation phenomena described via hidden variable evolution equations.
The Physics Department is committed to providing an exceptional education to our students. To that aim, we have updated our graduate program learning objectives to better align us with our Statement of Principles and the ever-advancing world.
Engineering Physics at NMSU is the only engineering physics degree program in New Mexico and in the Southwest. It is for students who want both to understand the fundamentals of physics and also apply science and math to real-life technical problems. Cooperative education and internship possibilities can give students hands-on work experience, which is important for students who want employment immediately after graduation.
The mission of the Engineering Physics program at New Mexico State University is to offer an accredited degree that combines high-quality engineering and physics programs to best prepare our graduating students for careers in state-of-the-art industry or to move on to advanced study in engineering physics.
