Author of:

More than 165 scientific articles and 7 book chapters.

Important Contributions:

  • Advanced ab initio crystal orbital theory and embedded-fragmentation methods for crystalline and amorphous solids and liquids.
  • Developed orbital-dependent density-functional theory based on optimized effective potential for ground and excited states.
  • Championed the use of symbolic algebra for automated formula derivation and parallel-execution code synthesis of high-rank electron-correlation methods.
  • Developed diagrammatic vibrational many-body methods for molecules and solids, introducing the concept of Dyson geometry and coordinates.
  • Reported theorems, proof, and conjecture concerning size consistency and the existence of thermodynamic limit.
  • Proposed a new finite-temperature many-body perturbation theory, elucidating the cause of its low-temperature breakdown.
  • Derived algebraic recursions for one-particle Green's unction and proved its linked-diagram and irreducible-diagram theorems within a time-independent framework.
  • Introduced stochastic algorithms for explicitly correlated many-body perturbation and Green's function theories and grid-based diffusion Monte Carlo.
