My research centers on the nanoscale patterns that develop spontaneously when a solid surface is bombarded with a broad ion beam. These patterns include ordered arrays of nanodots and surface ripples with wavelengths as short as 10 nm. From a more mathematical standpoint, I study self-organization in systems driven far from equilibrium as well as solitons and shockwaves.

My research focus is on high-precision laser spectroscopy of trapped highly charged ions for tests of fundamental physics. Highly charged ions provide a unique platform for investigating physics beyond the standard model including tests of quantum electrodynamics and searches for time-variation of the fundamental constants. We plan to combine techniques developed for quantum information processing and ion optical clocks with compact ion sources to create, trap, cool, and interrogate highly charged ions.

My research explores lateral confinement and coupling effects in nanomagnets through both experimental investigations and numerical modeling. In addition to being an exciting subject of study from a fundamental perspective, nanomagnets are also important for the advancement of technology, for example, in spintronics devices, storage media, and for medical applications. My present work focuses on the magnetization reversal and spin excitations of patterned magnetic elements.

My focus is in undergraduate student success. I develop tools for, collect data on, and analyze statistics of undergraduate student success -- both at the department level and as part of the assessment team at TILT (The Institute for Learning and Teaching). At the department level, I develop advising and recruitment materials, and I advise undergraduate students on their transition to the major.

Richard Eykholt / Associate Professor

My research has been in theoretical and mathematical physics, and its main focus has been on chaos and nonlinear dynamics. On the more formal side, I have developed new tools for analyzing nonlinear systems. On the more applied side, I have collaborated on research in atmospheric science, particularly with regard to predictability, spin waves in magnetic systems, and hydrology and streamflows.

My research is in the area of superconductivity, with a special emphasis on direct imaging of superconducting vortices and allied phenomena. Using scanning Hall probe microscopy, we are currently studying the dynamics of vortices in superconducting films that have an artificially structured periodic thickness modulation. We are also investigating phase-slip events in superconducting nanowire, again using imaging techniques to understand the relationship between local phase-slip dynamics and the microstructure of the wires.

My research is fully focused on DUNE (the Deep Underground Neutrino Experiment), which utilizes a neutrino beam produced at Fermilab, near Chicago. That beam will be characterized at Fermilab using the Near Detector, and the beam continues on to SURF (the Sanford Underground Research Facility) in South Dakota where a much larger detector, the Far Detector, will also measure neutrino interactions. I am currently working with colleagues at CSU to bring up a small prototype of the Near Detector. My physics interests on DUNE are in ideas of outside of the Standard Model of particle physics, including the possibility that dark matter could be produced in the neutrino beam at Fermilab along with the neutrinos.

My focus is on education and outreach. The outreach activities I pursue through the Little Shop of Physics dovetail nicely with my formal education responsibilities. Figuring out how to design instructional experiences that engage and educate younger students teaches me and my team valuable lessons about how to best engage and educate students at Colorado State University.

Michael Mooney / Assistant Professor

My research has been focused on understanding how to utilize the LArTPC (Liquid Argon Time Projection Chamber) technology for precision neutrino physics, with an emphasis on detector calibration and R&D of cryogenic electronics. I am participating in several LArTPC accelerator neutrino experiments, namely MicroBooNE (Micro Booster Neutrino Experiment), the SBN (Short-Baseline Neutrino) program, and DUNE (Deep Underground Neutrino Experiment), all of which utilize neutrino beams produced at Fermilab near Chicago, Illinois. The physics goals of these experiments include searching for a hypothetical particle known as a "sterile neutrino" and determining if neutrinos are responsible for the matter-antimatter asymmetry in the universe.

I have two areas of research interest. We are conducting experiments measuring fundamental plasma properties such as electron-ion collisions in strongly coupled and strongly magnetized ultracold plasmas. In a separate project, we are measuring the time-dependent absorption and birefringent response of atoms in an utracold gas to sudden laser illumination that occurs on timescales short compared to the atoms' response time.

Materials that host strongly interacting electrons can lead to new emergent phenomena, such as unusual particles with exotic properties that can only exist within these materials. Our work focuses on synthesizing and characterizing materials in which the spin degrees of freedom of the electrons lead to this kind of emergence. We use the concept of frustration (competition between different interactions) to design materials that host new quantum phases of matter, such as Quantum Spin Liquid states, which ideally will also host new emergent particles. We use inelastic neutron scattering, specific heat, magnetization, and ultrasound spectroscopy to characterize these materials.

My research is with the T2K neutrino experiment in Japan that first observed the muon type neutrino oscillation into the electron type neutrino. Our CSU group members designed, built and operated neutrino detectors, analyzed T2K data and published neutrino and antineutrino cross sections. Currently, the T2K collaboration is studying antineutrino oscillations that indicate charge-parity (CP) violation.

My current research interest is experimental neutrino physics including a search for sterile neutrinos, which cannot be produced or detected by any interaction but only come into being through a quantum mixing phenomenon. I enjoy teaching and exploring new methodologies such as the use of electronic response systems in the classroom and tutorial style homework problems.

My research focus is on precision spectroscopy of atomic hydrogen. Generally speaking, such experiments help determine the Rydberg constant, stringently test QED, and measure the RMS charge radius of the proton and deuteron. My group is particularly focused on new techniques to control the velocity of hydrogen, which we hope will lead to decreases in measurement uncertainty.
