Emergence is an important concept in the parlance of many-body systems. It relates to the idea that properties and phenomena that never appear in individual elements are realized in collections of huge number of elements with strong interactions between the constituents. In a solid, for example, electrons will have several degrees of freedom – charge, spin, orbital, topology etc. When these degrees of freedom closely interact, it can give rise to exotic phenomena as responses to external stimuli and manifest in the magnetic, thermal, electrical and mechanical properties. 21st century condensed matter physics has sailed away from simple atomic physics-driven systems to complex magnetic oxides and low dimensional materials that offer exotic ground states and excitations.The importance of such exotic magnetic states lies in the fact that they 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 that can realize a quantum computer even. The primary focus of the PI’s current research is the design of novel “frustrated” magnetic oxides realizing strongly correlated magnetic states of matter that can pave the way to future information technologies based on spin. In his laboratory at UTEP, the PI prepares single crystals of frustrated magnets and explores their fundamental physics using several experimental characterization tools. An important tool that he uses is neutron scattering, which can provide final and definitive answers to several advanced questions related to structure and dynamics of the magnetic system under investigation.
