Emergence is an important concept in condensed matter many-body systems. It is the idea that properties and phenomena that never appear in individual elements are realized in collections of them with strong interactions between the constituents. In a solid electrons will have several degrees of freedom like charge, spin, orbital, and topology. When these degrees of freedom closely interact, exotic phenomena can emerge in responses to external stimuli and manifest in the physical properties. Superconductivity, metal-insulator transitions, topological excitations, quantum spin liquids, multiferroicity are all examples of the fundamental concept of emergence. My research is in complex magnetic solids that show new types of emergent behaviour which can realize: (i) dissipation-less transport of spin or charge degrees of freedom, (ii) cross-coupling between electric and magnetic polarization leading to novel states that can store information, (iii) quantum entanglement between the spins in a solid. The novel materials that I study find applications as energy storage systems (batteries or supercapacitors), novel data storage materials (multiferroics), and quantum computing solutions (topological quantum computers). Discovery of new magnetic materials and elucidating their fundamental physics at the microscopic level using X rays and neutrons to manipulate their properties for transporting and storing information and energy is at the core of my research.
