Research Focus Category
Dr. Keumo Tsiaze Roger Magloire’s research primarily lies at the intersection of condensed matter physics, nanomaterials science, and quantum physics, with a particular emphasis on the thermodynamic, electronic, and quantum properties of low-dimensional systems. His work explores phase transitions, critical phenomena, and size effects in superconductors, ferromagnets, and multiferroics using advanced theoretical frameworks such as the renormalized Landau-Ginzburg-Wilson approach and renormalized Gaussian models. He is also deeply engaged in the study of superconductivity and magnetism in hybrid quantum structures, and the development of novel quantum information systems including superconducting qubits and tunneling wire-based “flying qubits.” His ongoing projects involve the theoretical and numerical modeling of two-dimensional transition metal dichalcogenides (TMDCs) as tunnel barriers in Josephson junctions, as well as the investigation of decoherence, excitonic dynamics, and electron-phonon interactions in nanostructures. Furthermore, he contributes to the understanding of structure-property relationships in emerging functional materials, aiming to develop phenomenological models that capture the interplay between fluctuations, quantum coherence, and material properties in constrained geometries such as quantum dots and layered heterostructures. His multidisciplinary approach integrates statistical physics, solid-state theory, and quantum field theory, making significant contributions to both fundamental physics and potential quantum technologies.
