Exploring chemical reactions in VASP

Date: Nov 06 - 08, 2024 Venue: Zoom event

We invite you to participate in a three-day workshop, Exploring chemical reactions in VASP, where you will learn basic and advanced simulation techniques for determining the kinetics of elementary reaction steps. You will develop a foundation within both the harmonic and anharmonic approaches and learn about the strengths and weaknesses of each. Simple and more complex reactions will be covered in detail to aid you in studying reactions in VASP.

Over three lectures, you will learn about the methods available in VASP for investigating transition states of chemical reactions. In the first lecture, you will be introduced to the complexities of applying machine learning (ML) to reactions. The second lecture will cover how to compute energetics within the harmonic approximation using static approaches, such as the nudged elastic band (NEB) technique and the improved dimer method (IDM) to find the transition state. These will then be transformed into reactant and product by following the intrinsic reaction coordinate (IRC). The final lecture will go through anharmonic energetics using molecular dynamics (MD) and biased sampling techniques to study rare events such as chemical reactions.

These lectures will be accompanied by two hands-on sessions. You will review each of the static methods before applying them to the rate-determining step in a zeolite-catalyzed reaction. These static techniques will set you up for computing reaction profiles using demanding ab-initio MD techniques, such as the Blue Moon ensemble. You will be assisted throughout these sessions by a team of VASP developers.

The techniques you learn in this workshop will aid you in solving your own problems with studying chemical reactions and add to your toolkit for investigating transition states in VASP.

Registration opens on October 06, 2024. Please save the date because the number of spots is limited.

Online VASP workshop: From setup to solution—getting started with VASP

Date: July 03 - 05, 2024 Venue: Zoom event

Join us for a comprehensive three-day workshop, From Setup to Solution—Getting Started with VASP, designed to provide beginners with a solid foundation in the fundamentals of Density Functional Theory (DFT) and the Projector Augmented Wave (PAW) method. Throughout the workshop, participants will explore the theoretical underpinnings of DFT and PAW, gaining a deep understanding of these essential concepts in computational materials science.

This workshop offers a hands-on approach to mastering VASP, guided by a series of three lectures focusing on key aspects of electronic structure calculations. The first lecture will introduce participants to the basics of DFT and the PAW method, laying the groundwork for understanding the principles behind VASP. The second lecture will explore techniques for converging the electronic structure, providing participants with practical insights into which algorithms are available and how to enhance the accuracy and efficiency of their simulations. The third lecture will focus on structure optimization, guiding participants through the process of setting up structures and relaxing them to achieve stable and realistic configurations.

In addition to the lectures, participants will engage in guided hands-on sessions, allowing them to apply the concepts learned in practice. Attendees will learn run some fundamental VASP calculations and explore all steps from input preparation to result analysis. Moreover, participants will have the unique opportunity to interact directly with the developers of VASP to discuss the tutorials as well as get advice on their own research.

Don’t miss this opportunity to kickstart your journey into the world of computational materials science with VASP. Whether you’re new to electronic structure calculations or looking to deepen your understanding, this workshop is your gateway to unlocking the full potential of VASP for research and discovery.

Registration opens on June 03, 2024. Please save the date because the number of spots is limited.
