Overview

The theoretical condensed matter group at TTU consists of two faculty members Prof. DeGottardi, 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. Prof. DeGottardi studies topological materials and low-dimensional quantum liquids and gases. Systems of interest include quantum wires, superconducting circuits, and photonic systems.

The experimental condensed matter group at TTU consists of six faculty members, Prof. Chatzakis, Prof. Duncan, Prof. Grave de Peralta, Prof. Hodovanets, Prof. Myoung-Hwan Kim, and Prof. Hyunsoo 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. Myoung-Hwan 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. Prof. Hyunsoo Kim is interested in understanding fundamental physics manifested in condensed matter systems, and he is also interested in the discovery of novel quasiparticles and their interactions in solid-state systems. Prof. Hodovanets focuses on the synthesis, characterization, optimization, and tuning of novel quantum materials (e.g. Weyl semimetals, superconductors, antiferro- and ferromagnets, magnetocaloric and thermoelectric 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.
