Research Projects

Rationale: The proposed research aims to investigate the emergence of superconductivity in topological half-Heusler compounds. By tuning these materials to a topological phase transition, we seek to understand the interplay between topology and superconductivity, potentially leading to the discovery of new quantum states of matter. Scientific Objectives: The proposal has two key scientific objectives: (1) Evolution of Superconductivity with Topological Character: To study the relationship between topological phase transitions and the onset of superconductivity in half-Heusler compounds. And (2) Quantum Criticality Tuned by Chemical Pressure: To investigate the emergence of quantum critical behavior near the superconducting phase transition in half-Heusler compounds. Hypothesis/Model to be Tested: We hypothesize that the topological phase transition in half-Heusler compounds can induce quantum critical fluctuations that promote the formation of superconducting Cooper pairs. Main Experiments to be Carried Out: Single Crystal Growth: Growth of high-quality single crystals of half-Heusler compounds with varying compositions and structural properties. Characterization: Comprehensive characterization of the grown crystals using techniques such as X-ray diffraction, magnetization, resistivity, and specific heat measurements. Pressure Studies: Investigation of the evolution of superconducting and topological properties under applied pressure. Transport Measurements: Detailed transport measurements to probe the electronic properties and identify signatures of quantum criticality. Significance to the Field of Research: Successful completion of this research will significantly advance our understanding of the interplay between topology and superconductivity, provide insights into the mechanisms of unconventional superconductivity and contribute to the development of theories for quantum critical phenomena. The research outcomes of the project will have potential applications in quantum computing and topological quantum devices, development of novel superconducting materials with enhanced properties, and advancements in energy-efficient technologies. By achieving these objectives, this research will significantly contribute to the field of condensed matter physics and open up new avenues for exploring exotic quantum states of matter.
