the complex systems, such as the 16-nucleon problem, using realistic microscopic nucleon-nucleon and three-nucleon interactions where only the low-energy modes are retained as well as the finite diagonalization within the low-energy space to obtain the spectra leading to detailed comparisons with experiments. He also focuses on the development of a covariant
Hamiltonian light-front approach called the basis
286:
His work employs similarity transformations, which seek to decouple the “low-energy” degrees of freedom from the “high-energy” degrees of freedom related to the renormalization group approaches in quantum field theory and the non-perturbative
Hamiltonian renormalization methods. His work addresses

Vary is known for his work in theoretical nuclear physics with an emphasis on effective
Hamiltonians for strongly interacting systems and for developing new ab initio approaches to the microscopic structure of nuclei for solving the fundamental nuclear many-body problems as well as problems in

He has also been the acting director of the
International Institute of Theoretical and Applied Physics, Ames, Iowa (1993-1997), director, International Institute of Theoretical and Applied Physics, Ames, Iowa (1997-2000). He leads the nuclear theory group at
291:(BLFQ) which leads to the ab initio descriptions of the mesons and baryons. He also works on the strong field (non-perturbative) scattering problems with a time-dependent extension to BLFQ (tBLFQ).
