PSI

Markus Ammann, head of the Multiphase Chemistry research group at the Paul Scherrer Institute PSI and adjunct professor of atmospheric chemistry at ETH Zurich, ranks considerations regarding the use of so-called geoengineering to put the brakes on climate change and explains what the Swiss Light Source SLS has to do with it.

Understanding how chemical reactions really happen at a quantum mechanical level is difficult. As experimental tools such as the SwissFEL enable new insights into the ultrafast changes that govern them, the data becomes too complicated to model classically. Here, simulations on quantum computers could help. 

At the European Organization for Nuclear Research CERN in Geneva, literally big plans for the future are being forged: The Future Circular Collider (FCC), with a circumference of 91 kilometres, would become the largest machine ever built by human hands. As an important member of the Swiss Institute of Particle Physics, the Paul Scherrer Institute PSIwill participate in this project. Lea Caminada, head of the High Energy Particle Physics Group at PSI, talks about the status of this undertaking.

An international study led by atmospheric researchers at PSI shows for the first time what portions of particulates in the air over northern India are especially harmful to health.

Today, machine learning and artificial intelligence are part of the toolkit for most researchers at PSI. In many cases these methods are fundamentally transforming the way we do science.
