Research Projects

The project aims to explore the exotic quantum phases of quasi-one-dimensional (quasi-1D) compounds in the family of linear-chain compounds (MX4)nI. These materials are expected to exhibit a charge density wave (CDW) condensate of conducting electrons, leading to complex low-energy dynamics such as nonlinear conductivity, a giant low-frequency dielectric constant, and exotic coherent dynamics from highly correlated electrons. The study will focus on the topological signature of the CDW condensate, the nonlinear optical response, and their potential as thermoelectric materials. The topological properties of the CDW condensate will be investigated using various experimental techniques, such as magneto-transport, 1/f low-frequency conductance noise spectroscopy, and dielectric response measurements under external electric and magnetic fields. The nonlinear optical response of quasi-1D compounds will be explored using Spatial Self Phase Modulation (SSPM) spectroscopy to estimate the enhanced nonlinear optical response. Thermoelectricity will be investigated as a potential application of quasi-1D semimetals due to their low thermal conductivity and high-power generation efficiency. By optimizing the electronic and thermal properties of these materials, new, more efficient thermoelectric devices can be developed, converting waste heat into useful electrical energy. The ultimate goal is to generate new knowledge and explore the potential for new technological applications.
