Dr. Himadri Barman is an accomplished theoretical physicist specializing in condensed matter physics with a particular emphasis on many-body physics. His expertise includes the Mott transition, high-temperature superconductivity, Kondo effect, and Anderson transition. To tackle the complexity of many-body problems, Dr. Barman employs sophisticated numerical methods such as the dynamical mean-field theory (DMFT). He has made significant contributions to the field by independently modifying a semi-analytical quantum impurity solver, the local moment approach, within the DMFT framework, and demonstrating its superiority over other contemporary impurity solvers.
Dr. Barman's research has extended to the study of transport and optical properties of the disordered Hubbard model using DMFT. In recent years, he has broadened his interests to include non-Hermitian (PT-symmetric) many-body physics and physics-informed machine-learning problems. With his extensive knowledge and experience, Dr. Barman has made significant contributions to the field of theoretical physics and is a respected member of the scientific community.
