Western Colorado's Selective University

Research

The physics program offers numerous research opportunities in theoretical and experimental physics for undergraduate students. Physics majors at Colorado Mesa University are required to take a total of four credit hours of senior research and senior seminar courses as well as possibilities for independent study and informal individual mentorship. This offers students opportunities for learning beyond the classroom, exposure to currently exciting developments in physics and development of research techniques and skills.

The CMU physics faculty are actively involved in research in a variety of fields and each has several publications in prominent journals and conference proceedings. Areas of current interest include:

  • Superconductivity and low temperature physics.
  • Material science and nanotechnology
  • General relativity and gravitation.
  • Quantum computing and quantum information.
  • Computational astrophysics.

Physics students at CMU frequently participate in summer research programs at other institutions, typically via the NSF REU program.

Research Areas

Research in the areas of superconductivity and low temperature physics at CMU is conducted by Prof. Bill Tiernan.

Einstein's theory of General Relativity (GR) describes gravitation as the curvature of space and time due to the presence of matter and energy. This theoretical construct has been heralded as one of the greatest achievements of the human mind whose validity has been confirmed through countless experiments and astronomical observations. In addition to predicting the now-measured bending of starlight by our Sun and to accurately accounting for the perihelion precession of Mercury, GR has given birth to several exotic creatures including black holes and neutron stars and to modern cosmology.

At CMU, research in GR has focused on gravitational scenarios involving space times with more than four dimensions. Recent work has included a high-energy Gauss-Bonnet modification to standard Friedmann-Robertson-Walker cosmology.

Research in the areas of general relativity and gravitation at CMU is conducted by Prof. Chad Middleton.

Information can be stored in the states of quantum mechanical systems and processed via a controlled evolution of such systems. Since the early 1980s there have emerged a variety of novel information processing protocols which use the characteristic quantum mechanical features of such systems to accomplish ordinary information tasks in ways far superior to those available to conventional computers. Examples include quantum algorithms for factorization and searching, quantum cryptographic schemes and quantum teleportation. Such quantum information processing tasks are generally related to aspects of quantum theory which are traditionally considered part of the foundations of quantum mechanics.

At CMU, research in this area is focuses on quantum algorithms. Recent work has involved methods for adapting and assessing quantum algorithms when applied to ensembles of quantum systems as well as considering algorithms from the perspective of unitary discrimination.

Research in these areas at CMU is conducted by Prof. David Collins.

Research in quantum field theory at CMU is conducted by Dr. Anwar Shiekh.

Astrophysics is the study of the physical laws and processes governing stellar objects, systems, and the evolution of the universe. Understanding these areas typically requires a synthesis of classical mechanics, electromagnetism, relativity, statistical mechanics, fluid dynamics and quantum mechanics.

Research efforts in this area at CMU are focused on developing analytical, numerical, and computational techniques in order to elucidate the physical phenomena. Topics considered include:

  • analytic models of exoplanetary atmospheres and radiative transfer in exoplanetary atmospheres,
  • the dynamics of accretion onto Sgr A* in the galactic center,
  • current sheet dynamics, reconnection physics, collisionless shocks, and particle acceleration in solar flares and astrophysical shocks using fluid based magnetohydrodynamic and Particle in Cell codes,
  • the effects of magnetic fields and thermal physics on variability in accretion disks around Neutron Stars, Black Holes, and White Dwarfs,
  • the effect of hydrodynamic turbulence on disks undergoing the MRI (magnetorotational instability), and
  • simulating the spectrum of GRB afterglows (in their relativistically expanding phase) using an emission process which accounts for the randomly oriented magnetic field which are (likely) to be found in these regimes.

Research in the area of analytical and computational astrophysics at CMU is conducted by Prof. Jared Workman.

Materials science pulls theory and experimental techniques from physics and chemistry to develop novel materials, as well as study and determine their properties, including, but not limited to, structural, vibrational, electric, and magnetic characteristics. Nanotechnology involves the study of materials smaller than 100 nanometers. Nanomaterials very often have dramatically different properties than their bulk counterparts.

Research in this area at CMU focuses on metal oxides, bulk and nano-sized, having applications to nuclear and renewable energy, such as lithium manganese spinel oxides, nickel ferrites, and organometal halide perovskites. Currently, The main technique for this characterization is X-ray diffraction for crystallographic information, but plans are underway to construct a temperature-dependent Raman facility to enable further research. The flexibility of this equipment allows for investigation on a near limitless range of materials.
