Overview

Instructor: Thomas Miller (Professor at Caltech and Entos co-founder) and Daniel Smith (Entos)

Time: Friday, April 10, 2020 — 1:30PM-4:00PM CT

Location: Zoom session only

Prerequisites: Working knowledge of basic electronic structure methods for chemistry/materials; basic Linux/Unix, Python, or Jupyter notebook skills; GitHub account

This course provides an introduction to the Entos quantum chemistry software. Entos enables ab initio molecular dynamics calculations on molecular and condensed-phase chemical reactions and other processes, with particular focus on mean-field (i.e., DFT), quantum embedding methods, and physics-based machine-learning for electronic structure. The software is built to easily integrate with research workflows, allowing integration via simple text I/O, JSON output, and interactive Jupyter notebooks. The tutorial will be divided into two parts. The first part will focus on Entos basics, including how to run and integrate the software, and how to perform standard calculations (geometries, transition-state searches, implicit solvation, excited states, NMR and other spectroscopic properties). The second part will focus on unique methods that are available in Entos, including molecular-orbital-based machine learning, embedding methods, and advanced methods for optimization and conformational searches. The course will include demonstrations and a cloud-based interactive tutorial.
