His work carried out in the field of Relativistic quantum chemistry brings together such families of science as Classical mechanics, Helical Dirac fermion and Random phase approximation. His work in Coupled cluster covers topics such as Electronic correlation which are related to areas like Statistical physics and Dirac.
Atomic physics, Density functional theory, Coupled cluster, Quantum mechanics and Molecule are his primary areas of study. He focuses mostly in the field of Atomic physics, narrowing it down to matters related to Hamiltonian and, in some cases, Electronic structure, Fock space and Quantum electrodynamics. His Density functional theory study combines topics from a wide range of disciplines, such as Embedding, Excitation, Molecular physics and Dipole.
His study looks at the relationship between Coupled cluster and fields such as Electronic correlation, as well as how they intersect with chemical problems. His work on Spinor, Atomic orbital, Electron and Theory of relativity as part of general Quantum mechanics research is often related to Formalism, thus linking different fields of science. His studies deal with areas such as Dissociation and Analytical chemistry as well as Molecule.
His primary scientific interests are in Density functional theory, Vibrational circular dichroism, Coupled cluster, Spectral line and Quantum. Lucas Visscher works mostly in the field of Density functional theory, limiting it down to topics relating to Molecular physics and, in certain cases, Tight binding, Magic angle spinning and Atomic units. His Coupled cluster study integrates concerns from other disciplines, such as Multireference configuration interaction, Dirac, Excited state, Relativistic quantum chemistry and Equations of motion.
His Relativistic quantum chemistry research entails a greater understanding of Atomic physics. His Atomic physics research is multidisciplinary, relying on both Extrapolation and Limit. His studies examine the connections between Quantum and genetics, as well as such issues in Electronic structure, with regards to Error function, Superposition principle and Field.
His main research concerns Coupled cluster, Excited state, Multireference configuration interaction, Density functional theory and Dipole. His studies in Coupled cluster integrate themes in fields like Tensor contraction, Tensor, Ionization energy, Implicit solvation and Hamiltonian. His Excited state research incorporates elements of Molecular physics, Tetrahedral symmetry, Plasmon and Fock space.
His Multireference configuration interaction study combines topics in areas such as Polarizable continuum model, Embedding, Theoretical physics, Dirac and Propagator. The Density functional theory study combines topics in areas such as Quantum chemical, Reactivity, Interaction energy and Absorption spectroscopy. His study in Dipole is interdisciplinary in nature, drawing from both Computational chemistry and Relativistic quantum chemistry, Atomic physics.
