Sayan Banik is a Senior Research Fellow at the School of Physical Sciences, National Institute of Science Education and Research (NISER), where he specializes in theoretical condensed matter physics with a focus on topological magnetism, multiscale materials modeling, and superconducting hybrid systems. His research spans first-principles electronic structure calculations, atomistic spin simulations, micromagnetic modeling, and Bogoliubov–de Gennes–based superconductivity studies, enabling a comprehensive understanding of emergent magnetic textures such as skyrmions, antiskyrmions, and topological soliton lattices. He has developed expertise in state-of-the-art computational tools including JUKKR, FLEUR, VASP, SPIRIT, MUMAX3, and custom tight-binding codes, supported by strong programming proficiency in Python, C++, Fortran, and scientific visualization environments. Sayan’s contributions include multiple high-impact publications in internationally recognized journals such as Physical Review B (Letters) and Advanced Science, where his works on noncollinear magnetism, skyrmion-antiskyrmion phases, and topological superconductivity have attracted increasing scholarly attention. His collaborative research engagements extend to the Peter Grünberg Institute, Forschungszentrum Jülich, working with eminent scientists in quantum condensed matter theory. His academic achievements are further supported by competitive fellowships, including the Junior/Senior Research Fellowship of the Department of Atomic Energy and the INSPIRE Scholarship of the Department of Science and Technology. He has also qualified multiple national-level examinations such as NET, GATE, JEST, JAM, and NGPE. Beyond research publications, Sayan has actively contributed to the scientific community through conference talks, poster presentations, participation in international schools, and teaching assistance roles in computational physics and laboratory courses. His work contributes to advancing theoretical frameworks that support future innovations in spintronics, quantum materials, and hybrid superconducting devices, offering long-term societal impact through potential applications in energy-efficient information technologies and quantum computing platforms. With a strong foundation in theory, expanding collaborations, and a steadily growing research profile, Sayan Banik represents a promising early-career researcher poised for significant contributions to next-generation condensed matter physics.
