Enlightening the Primordial Dark Ages
This thesis is dedicated to the exploration of the primordial dark ages: unknown physics during the earliest stages of the Universe’s expansion that have not yet been directly probed by observations. Cosmic inflation is a burst of exponential expansion of space after the “Big Bang”.

Algorithms
Many important topics in computer science, such as the correctness of software, the efficiency of algorithms and the modeling of complicated systems, depend on sound theoretical underpinnings. In the Theory group, we study these fundamental building blocks and develop verification methods to prove system…

Open Micro Cavities
We develop open micro cavities to trap light in small volumes and thereby increase the interaction with intra-cavity emitters. Important aspects in this development are the optical penetration in the mirrors, coupling between optical modes, and scattering and clipping losses.

The most stable microscope in the world
Making the most vibration-free, cryogenic scanning tunneling microscope in the world. A bold mission, but one that PhD candidate Irene Battisti successfully executed together with the Fine Mechanical Department. The new microscope might shed light on how unconventional superconductivity works. PhD Defence…

Dissociative chemisorption on transition metal surfaces
The dissociative chemisorption of a molecule on a transition metal surface represents a rate-limiting step in many heterogeneously catalyzed processes, whereby most chemicals are made. In spite of the importance of this reaction, an accurate first principles approach to modeling it does not yet exist.…

Accurate Probabilities for Highly Activated Reaction of Polyatomic Molecules on Surfaces Using a High-Dimensional Neural Network Potential: CHD3
An accurate description of reactive scattering of molecules on metal surfaces often requires the modeling of energy transfer between the molecule and the surface phonons. Although ab initio molecular dynamics (AIMD) can describe this energy transfer, AIMD is at present untractable for reactions with…
