Main Results of Scientific Work

The focus of research work has been in complex dynamical systems and their applications in quantum metamaterials. The methods are theoretical and computational. The researchers introduced the idea of self-induced transparency in quantum metamaterials, found new nonlinear systems where Parity-Time symmetry plays an important role, introduced and investigated systems with flat bands and focused on the role of dynamical chimeras in superconducting metamaterials. The scientists published, among others, a review article in Physics Report on superconducting metamaterials. In 2018-2020, the researchers introduced machine learning in education, held courses in machine learning for NUST MISIS students and postgraduates, applied the machine learning method in researches and focused on the use of neural networks in nonlinear physics equations.
