Recruitment poster MIS Physics Degree

 

The department of Physics and Astronomy has offered a Five Year Integrated Masters in Physics since 2012. In this program students can graduate in 5 years with both a Bachelors degree and a Masters degree.

Intergrated MS Physics Program of Study

The program is rooted in the exceptionally strong world class research program in the department. Research areas span cutting edge programs in Gravitational Wave and Radio Astronomy, Applied Optics and Lasers, Nano-sciences, Astroinformatics and Biophysics. The department has established high standards in education by incorporating undergraduate research into the curriculum right from the beginning. There are six state of the art laboratories in the department that house some of the most powerful lasers, remote control access to the world's largest radio telescope, atomic force microscopes, cryogenic materials research devices, and very powerful computer clusters. The department has a cooperative Ph. D Physics program.

Society of Physics Students

The Society of Physics Students (SPS) is a professional association explicitly designed for students. Membership, through collegiate chapters, is open to anyone interested in physics. The only requirement for membership is that you be interested in physics. Besides physics majors, our members include majors in chemistry, computer science, engineering, geology, mathematics, medicine, and other fields.

Within SPS is housed Sigma Pi Sigma, the national physics honor society, which elects members on the basis of outstanding academic achievement. This unique two-in-one society operates within the American Institute of Physics, an umbrella organization for ten other professional science societies.

Regular Meetings are held on Wednesdays at 12PM in Rusteberg 205.

Physics Student Lands Internship at Facebook, Inc.

Ali-Amir Aldan, a sophomore physics major at The University of Texas at Brownsville, hit the jackpot with his summer internship at Facebook in Menlo Park, California. As a member of Kazakhstan’s national competitive programming team, he selected UTB upon recommendation from his coach to work with Dr. Malik Rakhmanov, Assistant Professor of physics at the Center for Gravitational Wave Astronomy, who is originally from Kazakhstan. Aldan’s participation on his country’s national competitive programming team put him in a position to be spotted by Facebook, and the company contacted him for the summer internship. For more info

Fermi-normal (FN) coordinates provide a standardized way to describe the effects of gravitation from the point of view of an inertial observer. These coordinates have always been introduced via perturbation expansions and were usually limited to distances much less than the characteristic length scale set by the curvature of spacetime. For a plane gravitational wave this scale is given by its wavelength which defines the domain of validity for these coordinates known as the long-wavelength regime. The symmetry of this spacetime, however, allows us to extend FN coordinates far beyond the longwavelength regime. Here we present an explicit construction for this long-range FN coordinate system based on the unique solution of the boundary-value problem for spacelike geodesics. More...


Nanoenergetic systems also known as metastable intermolecular composites (MIC) have various potential applications as propellants, explosives, and primers. The development of novel MIC systems, their design, synthesis and fabrication procedures are critical for national security and it was recognized as a significant addition to support of changing force structure for advanced weapons platforms. Our research at UTB focuses on developing a framework of principles for design and fabrication of nano-tailored highly energetic systems and nanoenergetic gas generators (NGG) for advanced energetic platforms. This involved a systematic study of physics based knowledge in energy release, shock waves and pressure discharge needed to enhance the performance and functionality of novel high density energetic systems.

Galaxies appear simpler than before” by Disney et al. The image shows a montage of coloured images of a dozen galaxies (huge whirlpools of stars in space) drawn from our survey of the universe, which is the subject of the letter. As well as being very beautiful they have considerable scientific interest too because they show a wider variety of galaxies than it has been possible to portray before. Hitherto galaxies were found optically, and hence tended to look rather like one another. These, however, were picked up in a radio survey and imaged only afterwards. Consequently they exhibit a much wider range of colours, shapes and surface brightnesses. Intriguingly some of them, although close-by in cosmic terms, are almost, but not quite, invisible. We believe both astronomers and laymen will find them fascinating. Copyright belongs to one of the co-authors, Andrew West. Read article...

Although predicted by S. Rytov more than sixty years ago the experimental proof that radiative heat transfer can be exponentially improved by reducing the gap between two surfaces of different temperature was only recently demonstrated for macroscopic objects with a geometry that can be compared with theoretical predictions. The scientists from the University of Florida and the University of Texas at Brownsville demonstrated good agreement between theoretical prediction and measurement. When an “infinite” warm surface is separated from a cooler one by a vacuum gap, the rate of radiative heat transfer between the two shouldn’t depend on the size of the gap. According to theory, though, this picture doesn’t hold when the surfaces are sufficiently close. In the paper "Near-Field Radiative Heat Transfer between Macroscopic Planar Surfaces" (Phys. Rev. Lett. 107, 014301, 2011), the scientists focused on a straightforward planar geometry. The heat transfer between two parallel square sapphire plates, each about two inches on a side, was measured for separations from a 0.1 mm down to only a few microns. A pronounced increase in heat transfer is seen as the gap between the plates is reduced following the theoretical predictions. In principle, near-field heat transfer could be used to control the temperature of an object without ever contacting it. This is an interesting possibility for cooling the sensitive mirrors in future gravity wave detectors.


Using recent data from the LIGO interferometers, LIGO scientists have been able to constrain the fractional energy density in gravitational waves to < 6.9 x10-6 (at 95% confidence) in a ~100 Hz band around 100 Hz. This number improves on indirect limits on the gravitational wave background obtained from the relative abundance of light elements in the very early universe (Big Bang Nucleosynthesis). The attached figure shows various limits on the gravitational wave background and predictions from three different models (inflation, pre-Big Bang cosmology, and cosmic strings). The indirect limits are from Big Bang Nucleosynthesis and the Cosmic Microwave Background; the direct limits are from the LIGO S4 and S5 science data (see attached paper), and from pulsar timing data. Projected limits from the advanced LIGO detectors, the CMB Planck satellite mission, and the proposed space-based interferometer LISA are also shown. More...


We study the fluctuation-induced, time-dependent force between two plates confining a correlated fluid which is driven out of equilibrium mechanically by harmonic vibrations of one of the plates. For a purely relaxational dynamics of the fluid we calculate the fluctuation-induced force generated by the vibrating plate on the plate at rest. The time-dependence of this force is characterized by a positive lag time with respect to the driving. We obtain two distinctive contributions to the force, one generated by diffusion of stress in the fluid and another related to resonant dissipation in the cavity. The relation to the dynamic Casimir effect of the electromagnetic field and possible experiments to measure the time-dependent Casimir force are discussed. More...
