Symmetries of Differential Equations and Applications (SDEA) |
Brief Description of Overall Research |
The study of nonlinear differential equations describing physical systems and finding their exact solutions remain the central focus of research for the past few decades. Finding exact solutions of these nonlinear equations, which can be either ordinary differential equations (ODEs) or partial differential equations (PDEs), is one of the most important tasks and their further investigation plays an essential role in the study of nonlinear physical phenomena. We utilize the Lie symmetry group methods which have been proved to be indispensable and powerful tools for studying such nonlinear problems arising in many scientific fields including mathematics, engineering, physics and other mathematically-based sciences. Moreover, inter alia, we use symmetries and other means to obtain conservation laws of system of ODEs and PDEs as they have significant uses in the study of the analysis of stability and global behaviour of solutions and in developing numerical methods for these nonlinear differential equations. Linearizing transformations for nonlinear ODEs are also studied. Furthermore, we investigate construction and generation of approximate invariant solutions and approximate conservation laws by making use of approximate Lie-Bäcklund symmetry generators of a given system of perturbed or approximate ODEs and PDEs. |

Physics of Strongly Correlated Materials (PSCM) |
Brief description of overall research |
Strongly correlated cage compounds (SCCC) are conceived to unify within a single material, the specific properties of strongly correlated electron systems (SCES) and cage compounds. SCES can give rise to a large variety of peculiar phenomena such as heavy-fermion behavior, unconventional superconductivity, Kondo-insulating behaviour, intermediate valence, non-Fermi liquid behavior, and quantum criticality.In heavy-fermions and the Kondo insulators, the ground state results from the competing exchange interactions of the Kondo and the Ruderman-Kittel-Kasuya-Yosida (RKKY) interactions. The competing effect of Kondo and the RKKY interactions admixed furthermore with the crystal electric field effect are known to produce a wealth of exotic quantum states, for example, valence fluctuation, spin reorientation, long-range magnetic ordering, semiconducting heavy-fermion behavior, ferromagnetic quantum criticality, non-Fermi liquid behavior, spin gap formation, antiferromagnetic superzone gap formation. In heavy-fermions, the c-f hybridization electrons lead to Kondo spin compensated state and which can result in a substantial enhancement of thermoelectric power and anomalous behaviour of the transport, thermal and magnetic properties. Some of these properties become favorable for devising thermoelectric materials. |
