💡 Research Topics

The Quantum Magnetism and LowDimensional Materials group studies functional materials in which quantum effects determine electronic, and magnetic properties. Our research spans rare-earth oxides, perovskite manganites, and 2D transition-metal dichalcogenides. We investigate strongly correlated electron systems, superconductivity, magnetoresistance, spin dynamics, quantum confinement, and energy-driven processes. Advanced characterizations, including μSR, neutron scattering, Raman spectroscopy, synchrotron spectroscopy, and electron microscopy, link fundamental condensed matter physics with applied materials science. Current projects focus on magnetocaloric oxides for energy-efficient cooling, oxide and dichalcogenide heterostructures for sensors, and materials for solar energy conversion and environmental remediation. These efforts aim to uncover new physical mechanisms while guiding the design of materials for next-generation energy, sensing, and quantum technologies.

In this group, we focus on leveraging quantum computing for applications in finance and complex systems. Specifically, we implement and develop efficient hybrid quantum-classical algorithms, such as the Variational Quantum Eigensolver (VQE) and the Quantum Approximate Optimization Algorithm (QAOA), with targeted use cases in financial sectors (combinatorial optimization, portfolio diversification, and risk profiling). Beyond financial applications, we also extend the use of hybrid quantum algorithms to problems in quantum chemistry and drug discovery. Furthermore, in our group, we also investigate opinion dynamics models by analyzing various statistical properties on complex networks, such as the emergence of phase transitions and scaling phenomena induced by external influences. This research is conducted both analytically and computationally across a range of model scenarios.

Our research group focuses on the theory and phenomenology of particle physics, with a specific emphasis on elementary particles and their interactions. Our work is centered around the standard model and its extensions, which include areas such as neutrino oscillation, Higgs physics, B-Physics, dark matter, quantum field theory, and grand unified theory.

We research experimental high-energy physics and, recently, we have also branched out into applications of high-energy particle detection technology, known as muography. At an extremely high temperature, close to the temperature an instant after the big bang, protons and neutrons in atomic nuclei will break into their constituents of quarks and gluons. Our group use experimental facilities at CERN, Geneva, Switzerland, and computing facilities at BRIN to probe and study the behavior of quarks and gluons at this extremely high temperature. Our particular interest is the physics of heavy quarks (b and charm) probed by producing corresponding b- and charmed mesons. In muography, we are exploring potential muography applications in geoscience and non-destructive testing.

The Single-Crystal Research Group focuses on the growth and characterization of high-quality single crystals for exploring novel quantum and functional materials. Our research covers metallic superconductors, heavy-fermion compounds, kagome-lattice materials, and thermoelectric materials, with particular interest in their electronic, magnetic, and transport properties. We utilize Bridgman and flux-growth techniques to synthesize high-quality bulk single crystals with controlled composition and crystallographic quality. These crystals provide a platform for investigating emergent phenomena arising from strong electronic correlations, unconventional superconductivity, frustrated magnetism, non-trivial band structures, and thermoelectric transport.

Keywords: Single-crystal growth, superconductivity, heavy fermion, kagome lattice, thermoelectric materials, quantum materials, electronic transport, magnetism.

We are a multidisciplinary research group investigating how the quantum properties of materials govern photon-driven catalytic processes and energy conversion. We focus on quantum materials with strong spin–orbit coupling, such as Bi₂Se₃. In addition, we specialize in developing highly porous, template-free carbon-based materials, including carbon nitride and carbon nanotubes, to build a library of single-atom catalysts. Our research combines materials synthesis with atomic-scale characterization, particularly X-ray absorption spectroscopy and X-ray fluorescence holography, together with computational approaches, such as combined density functional theory and ab initio molecular dynamics studies, to predict material properties and establish structure–property relationships. Because photon-driven catalysis involves the generation and evolution of photoexcited charge carriers, we also employ, together with our collaborators, time-resolved spectroscopies, including time-resolved microwave conductivity, time-resolved absorption spectroscopy, and time-resolved photoluminescence, to elucidate charge-carrier generation, transport, separation, trapping, and recombination. By integrating these approaches, we seek to understand how atomic and electronic structures translate into catalytic activity and selectivity. Our research ultimately aims to establish fundamental principles for solarenergy conversion and sustainable chemical synthesis, targeting solar fuels such as hydrogen, hydrogen peroxide, and ammonia, as well as the selective production of value-added chemicals. Through the integration of quantum materials, spectroscopy, computation, and catalysis, we aim to bridge fundamental quantum phenomena with practical solutions for sustainable energy and chemical production.
