Condensed Matter Physics



The theoretical condensed matter group at TTU consists of three faculty members, Prof. Estreicher, Prof. Myles, and Prof. Sanati. The group is active in two main areas: crystalline semiconductors and metallic alloys. We combine theoretical and computational methods to investigate the mechanical, optical, electrical, and thermal properties of materials.

The experimental condensed matter group at TTU consists of four faculty members, Prof. Duncan, Prof. Grave de Peralta, Prof. Chatzakis and Prof. Kim. Prof. Grave de Peralta's research in NTC concentrates on Fourier and ultra fast optics, plasmonics and mechanical properties of light. In addition, he is interested in the fundaments of Quantum Mechanics (Quantum Optics). Prof. Kim is interested in gradient optical metasurfaces for flat optics and integrated photonics applications, quantum information and control using condensed matter systems, and the fundamentals of anomalous Hall behavior in quantum materials. Prof. Chatzakis focuses on the study of the optical and electronic properties of nanoscale materials and structures in particular on ultrafast dynamical processes in nanomaterials and nanostructure compositions, but also he is interested in the light manipulation and confinement beyond the diffraction limit for next generation photonic applications, and he explores novel methods for generating/controlling the THz radiation by graphene and metamaterials, and he study the quantum light emitters (single photon sources) based on two dimensional materials.

NTC is a conglomerate of laboratories facilities. NTC projects include researchers, graduate, and undergraduate students from Electrical, Computer, Chemical, and Mechanical Engineering, Physics, Computer Science, Biology, Chemistry, and Medicine. Research is supported by numerous Federal, State, and Industrial grants. The Center supports new education programs in MEMS, Silicon Processing, and Semiconductor Product Engineering.
