How To Install aces3 on Ubuntu 20.04

In this tutorial we learn how to install aces3 on Ubuntu 20.04. aces3 is Advanced Concepts in Electronic Structure III

Introduction

In this tutorial we learn how to install aces3 on Ubuntu 20.04.

What is aces3

aces3 is:

ACESIII is an electronic structure calculation program with a focus on correlated methods. It is the parallel successor to ACESII, employing the Super Instruction Assembly Language (SIAL) as parallelization framework. Features include:

Energies, analytic gradients and analytic hessians for the following methods:

  • Restricted/unrestricted spin or restricted open-shell Hartree-Fock (HF)
  • Second-order Moeller-Plesset pertubation theory (MP2)

Energies and analytic gradients for the following methods:

  • Coupled cluster singles and doubles (CCSD)

Additionally, it can compute energies for the following methods:

  • Coupled cluster singles and doubles with pertubative triples (CCSD(T))
  • Quadratic configuration-interaction singles and doubles (QCISD)

Excited states can be calculated by the following methods:

  • Qadratic configuration interaction singles and doubles
  • Coupled cluster equation-of-motion (EOM-CC)

It also includes an internal coordinate geometry optimizer. If analytic gradients are not available, numerical gradients via finite differences are used.
