Dirk Bouwmeester Lab - Quantum Optics and Quantum Information
The research program of the QO group has three leading themes: Optical Physics, Quantum Optics, and Photon-Matter Interactions. We work mostly at the boundaries between these themes with entanglement as a bridging and binding agent.

Searching explanations for mysterious structures in protoplanetary disks
In the discs of dust and gasses around young stars, mysterious structures occur. Together with professor Ewine van Dishoeck, PhD student Paolo Cazzoletti investigate how we can explain these forms, such as rings, spirals and holes. On 12 December, he will defend his thesis.

Linking simple molecules to grain evolution across planet-forming disks
Planets are formed in disks of gas and dust around young stars.
-
Mining the kinematics of discs to hunt for planets in formation
Detecting planets during their formation stages is crucial for understanding the history and diversity of fully developed planetary systems like our own. However, observing young planets directly is challenging because they are often deeply embedded within their host protoplanetary discs, rich in gas…

Imaging the water snow line within a protoplanetary disc
Research using the ALMA telescope by scientists including Leiden's John Tobin and Steven Bos has produced the first images of the water snow line within a protoplanetary disc. Publication in Nature on 14 July.

Chemistry in embedded disks: setting the stage for planet formation
To address the fundamental questions of how life on Earth emerged and how common life may be in the Universe, it is crucial to know the chemical composition of the planet-forming material.

In memoriam – Dirk Huyge (1957 – 2018)
NVIC suffered a great loss by the passing of Dirk Huyge, curator of Prehistoric and Early Dynastic Egypt at the Art & History Museum, Brussels. Dirk Huyge will always be remembered for his role in establishing a systematic approach for rock art research in Egypt. May all the beautiful memories be…

Turtles all the way down: multiscale simulations connecting star and planet formation
The formation of stars and planets happens over multiple scales, which can interact. In particular, planet formation happens in the dense, complex environment of star forming regions.

Freezing conditions in warm disks: snowlines and their effect on the chemical structure of planet-forming disks
This thesis focusses on the temperature structure in protoplanetary disks. The relation between structures seen in the dust and gas-phase molecules is investigated.
