QUANTUM THEORY OF MAGNETIC AND SPIN-DEPENDENT PHENOMENA: Magnetic and spin-dependent quantum phenomena, such as ferromagnetism, antiferromagnetism, magnetoelectricity, spin Hall effect and quantum spin liquids, are worth investigation from both fundamental and application point of view. To this end, the primary goal is to unravel the material-property duality based on materials specific quantum mechanical calculations, this being, the fundamental step in the designing of new materials with new and/or enhanced magnetic functionalities. Systems of interest include bulk materials, thin film and artificial heterostructures.

THE ROLE OF ATOMIC ORDER/DISORDER ON FUNCTIONAL PROPERTIES OF MATERIALS: In a material, the arrangement of constituent atoms in their respective sublattices significantly influences the properties of the material. The group, therefore, is interested in exploring the stability of the atomic ordered/disordered phases coupled with other microscopic degrees of freedom and their respective influences on the properties of materials. Such an approach would lead to the discovery of new stable/metastable phases with novel functionalities, such as superconductivity, magnetism, magnetoelectricity and negative thermal expansion.

MATERIALS' PROPERTIES AT LOW DIMENSION: Dimension has a significant bearing upon the physical and chemical properties of materials. Often with the reduction of dimension, emerge unique and fascinating electronic and magnetic properties. The emergent properties have high impacts in electronics, energy storage and production. Thus, the aim is to uncover phenomena in materials at low dimension.
