Welcome to the ONETEP webpage!

ONETEP (Order-N Electronic Total Energy Package) is a linear-scaling code for quantum-mechanical calculations based on density-functional theory.

Read this introduction for more details.

The Science Focus pages describe recent methodological advances and applications of ONETEP to biology and surfaces, nanostructures and defects.

Three new pieces of exciting work have recently been published with the help of calculations using ONETEP. The 'Focus' pages have been updated to describe them:

  • The Nanostructures and Defects page now describes fascinating work by David O'Regan and co-workers, published in Nature Materials, on a new type of quantum dot that self-assembles in core-shell GaAs/AlGaAs nanowires, and involving ONETEP simulations of up to 12168 atoms!
  • The Biomolecular simulations page now describes Cedric Weber's exciting recent Physical Review Letters paper describing the application of ONETEP Dynamical Mean Field Theory calculations to the heme molecule, investigating its binding to CO and O2.
  • The Methodological Advances page now describes Louis Lee's work on Natural Bond Orbital analysis, which made it onto the front cover of J. Comp. Chem!

New 'Focus' pages describing recent developments and applications of ONETEP:

  • Nanostructures and Defects, including investigations of the polarisation of wurtzite-structure nanorods of thousands of atoms
  • Biomolecular simulations, including investigations of protein-protein interfaces and drug optimisation
  • Methodological Advances, including developments to treat strongly-correlated systems, model solvation, correctly describe unoccupied states with local orbitals, and accurately treat the electrostatics of large systems.
