Unconventional Superconductivity

When certain metals are cooled to low temperatures, the electrons within form pairs that condense into a single quantum state. This superconducting phase exhibits a number of striking features, including electrical conduction without resistance and the expulsion of magnetic fields.
Recently, a new class of superconductors has been predicted to exist with unique pairing symmetries. Astoundingly, these “topological” superconductors can potentially be harnessed to build a quantum computer that is immune to environmental noise. Towards this goal, our group is interested in discovering, characterizing, and engineering new unconventional superconductors.

Ultrafast Scattering

Ultrafast Scattering is a pump-probe experimental techniques using an optical beam to pump the sample and X rays/ electron/ optical beam to probe the dynamical changes due to optical excitation. These techniques allow probing of femtosecond (fs) scale photoinduced dynamics and transient changes in electronic, phononic and structural states.

Two-dimensional Magnetism

Two-dimensional magnets are materials that exhibit a magnetic ground state when their thickness is reduced to a few nanometers or less. The reduction in the dimension is usually achieved by exfoliation techniques. 2D magnetism is usually associated with strong intrinsic spin fluctuations.

Byron Freelon

Byron Freelon, assistant professor of physics, has been named a Fulbright Scholar for 2024-25, expanding his efforts to promote the representation of Black physicists while building the scientific workforce needed to interpret data produced by X-ray synchrotrons.

Uchenna Ubeh

Uche is from Enugu state in Nigeria where he graduated from the University of Jos with a bachelor’s degree in physics and a master’s degree in physics from Auburn University. He joined the eXn group at the University of Houston in the summer of 2021. He is interested in characterizing the structural and magnetic properties of strained 2D materials using x and neutron scattering techniques. In his spare time, he enjoys playing soccer, playing video games, cooking, and spending time with his friends and family.
