Axions: From Heaven to Earth
01/09/2017 - 31/08/2022

Axions are hypothetical particles whose existence would solve two major problems: the strong P, T problem (a major blemish on the standard model); and the dark matter problem. It is a most important goal to either observe or rule out the existence of a cosmic axion background....


Understanding the speed limits of magnetism
01/02/2017 - 31/01/2022

While the origin of magnetic order in condensed matter is in the exchange and spin-orbit interactions, with time scales in the subpicosecond ranges, it has been long believed that magnetism could only be manipulated at nanosecond rates, exploiting dipolar interactions with ext...


Nanocalorimetry: new opportunities in thermodynamic characterization
01/01/2017 - 31/12/2020

Specific heat measurements provide the fundamental thermodynamic signatures that are needed to understand and interpret novel material properties. We will apply our unique phase-stabilized differential ac-nanocalorimeter to perform measurements with an unprecedented combinatio...


Action spectroscopy with cold, gas-phase molecular ions at DESIREE
01/01/2017 - 31/12/2020

With this starting grant, I propose to build up new instrumentation to study the intrinsic electronic properties and photoprocessing of cryogenically cooled, gas-phase molecular ions. I will use a combination of optical spectroscopy and mass spectrome called action spectroscop...


Formation, survival, and destruction of complex molecular systems
01/01/2017 - 31/12/2020



This project aims to advance our knowledge on how complex molecules respond to light and energetic particles, and how they are formed and survive in nature and in space. The goal is to contribute to solve outstanding questions in sc...


Time domain: the next revolution in astrophysics and cosmology
01/01/2017 - 31/12/2020






A revolution in cosmic transient science is taking
place right now: we are ready to start discovering cosmic events with
characteristic time scales of hours or even minutes, dramatically
expanding the ra...

Anomalous Water
01/01/2017 - 31/12/2020

Understanding the structure and dynamics of the H-bonding network in water is essential for many problems in chemistry, physics and biology. Here we will develop and apply improved techniques to compute x-ray spectroscopic observables for water where we specifically include th...


Many-body calculations on atomic systems exposed to extreme light-pulses
01/01/2017 - 31/12/2020
A key to understand many process that can lead to break-up of quantum systems is theinitial charge migration due to electron dynamics that follows directly after photon or particle impact, and which precedes nuclear motion. The extremely short laser pulses that are available...

Probing the Structure and Dynamics of Water in its Various States
01/09/2015 - 31/08/2020
We propose to address some of the most important outstanding questions for a microscopic understanding of water: What is the structure and dynamics of the hydrogen-bonding network that give rise to all the unique properties of water? How is the structure and dynamics affecte...

Physics of interacting spin-2 fields and its applications
01/01/2016 - 31/12/2019

Elementary particles and the fields that mediate interactions between them are classified based on their "spin". At the fundamental level we encounter fields of spin 0, 1/2, 1 and 2. By now, we have consistent theories for fields of spin 0, 1/2 and 1 and these are the building...
