Welcome to the web page of the IQM group!
We are a Materials Physics group in the Department of physics, IISc Bangalore, India.
The concepts of symmetry, topology, and interactions are the fundamental pillars of the modern condensed matter physics. Our research focuses on the external manipulation of these factors to generate emergent electronic and magnetic phases of matter using transition metal oxides and transition metal nitrides as model materials. To achieve these goals, we have pioneered the epitaxial growth of diverse artificial structures of complex oxides using Laser MBE. Engineering atomically sharp interfaces between dissimilar materials induces symmetry breaking, leading to the emergence of novel electronic and magnetic properties. Another key direction of our research involves breaking symmetry across all length scales within long-range ordered structures. This is achieved through compositionally complex oxides, including the well-known high-entropy oxides. Our group's investigations encompass single-crystalline thin films and bulk materials.
We perform transport measurements under various external fields (light, electric, magnetic fields). We use synchrotron-based techniques (X-ray diffraction, X-ray photoemission spectroscopy, X-ray absorption spectroscopy, X-ray scattering, extended X-ray absorption fine structure) to gain a microscopic understanding of various emergent phenomena. These experiments are carried out in various synchrotron centres: Advanced Photon Source (USA), Advanced Light Source (USA), PETTRA (Germany), Elettra (Italy), Photon Factory (Japan). We also collaborate actively with several national and international groups for complementary experimental techniques and theoretical expertise as a comprehensive understanding necessitates a multi-faceted approach.
