ALGC Research Group

In the laboratory ALGC VUB Materials Modeling, we have been investigating physico- chemical properties of solids for 2 decades. The tools we use are those of quantum chemistry, but also those involving classical Force Fields. Over the years we have been particularly interested in periodic density functional theory (DFT). The solids (and materials in general) and the solid liquid interface models, that we have studied can be grouped into three main categories: silica-based materials, noble metals and bio- and biological materials (mainly biological calcifications). The goal of our research is to characterize these complex materials at the atomic and molecular level. For this we build unique and calculable models. The properties derived from the obtained electron density obtained from ab initio methods, have brought us to collaborate closely with experimentalists in very different fields such as: chemical engineering, material chemists, geology, catalysis, pharmacy, medicine, and archeology. In summary we use theoretical and computational chemistry combined with experimental methods to characterize and understand materials.

DNA Hairpins for Asymmetric Catalysis



Organic Chemistry Research Group

Organic chemistry (ORGC) is most commonly defined as the chemistry of carbon compounds. Compared with hydrogen and helium, carbon is not an abundant element in the universe, nor in the solar system; but it is an essential element of life. Indeed, four elements: carbon, hydrogen, nitrogen and oxygen make up most of the matter found in living organisms. Trace elements such as sulfur, phosphorous, sodium, potassium and iron, to name a few, also play an important role in the chemistry of life; but it is the unique properties of carbon that permits the immense diversity of compounds associated with life...

High Energy Physics

Unique on the Belgian scale, about 23 professors at the VUB perform fundamental research towards a profound and comprehensive understanding of both the largest and smallest structures around us. Combining theoretical and experimental research of high-energy phenomena in the universe and on the quantum scale we aim to unravel the laws of nature at the most fundamental level. This effort is concerted in a flourishing HEP@VUB Research Centre which excels internationally. To achieve a coherent global picture of the reality around us, puzzling features that challenge the underlying basic principles in physics on large and small scales have to be studied and understood. The foundations of the Standard Models of both particle physics and cosmology face problems to explain for example the omnipresence of dark matter and dark energy, as well as the apparent need for fine-tuning in several corners of our models and the difficulty to unite all forces. Novel theoretical reasoning and further experimental explorations will provide insights towards solutions. The recent creation and now further consolidation of our phenomenological research activities are essential to profoundly connect theory and experiment, as well as to connect the studies of large-scale and small-scale features.

At the foundation of the HEP@VUB Research Centre is the involvement in a variety of large-scale research infrastructures around the world. At colliders our long-term engagement is focused on the studies of proton collisions with the CMS experiment at the LHC at CERN both for precise measurements and for searches. We develop analysis and reconstruction techniques and take responsibility in the upgrade of the all-silicon CMS Tracker. Recently, we started to explore physics studies at future colliders. For neutrino physics our research revolves around the very-short baseline SoLid experiment at the BR2 nuclear reactor at the SCK-CEN, Belgian’s leading nuclear laboratory. The IceCube Neutrino Observatory at the South Pole is our main infrastructure for astroparticle physics with a focus on multi-messenger astrophysics, complemented with the Auger observatory in Argentina for cosmic ray studies and novel radio detector arrays being installed on the South Pole and on Greenland in the search for ultra-high-energy neutrinos. The radio interferometric array of LOFAR, situated mainly in the Netherlands, allows us to observe and study high-energy astrophysics phenomena. Recently we engaged in gravitational wave research with the Virgo/LIGO interferometers, in the USA and Italy, and towards the new Einstein Telescope potentially situated partially in Belgium. Additionally, a broad range of theoretical topics in the area of string theory and holography is offered, often involving links to other fields in physics. Through phenomenological research we develop methods and tools towards an overall interpretation of the experimental results in existing theories and to build novel models to be confronted with experimental observations. The explicit phenomenological research has a focus on beyond Standard Model physics related to supersymmetry, dark matter, cosmology and inflation, but in astroparticle and collider physics.

Multi-messenger Studies of Cosmic Phenomena with the IceCube Neutrino Observatory



Exploring the High-Energy Neutrino Universe



Inter University Institute For High Energies

The Interuniversity Institute for High Energies, IIHE (ULB-VUB), was created in 1972 at the initiative of the academic authorities of both the Université Libre de Bruxelles and Vrije Universiteit Brussel. Its main topic of research is the physics of elementary particles.

The present research programme is based on the extensive use of the high energy particle accelerators and experimental facilities at CERN (Switzerland) and DESY (Germany) as well as on non-accelerator experiments at the South Pole.
The main goal of this experiments is the study of the strong, electromagnetic and weak interactions of the most elementary building blocks of matter. All these experiments are performed in the framework of large international collaborations and have led to important R&D activities and/or applications concerning particle detectors and computing and networking systems.
Research at the IIHE is mainly funded by Belgian national and regional agencies, in particular the Fonds National de la Recherche Scientifique (FNRS) en het Fonds voor Wetenschappelijk Onderzoek (FWO) and by both universities through their Research Councils.

Analytic theory of tensor C*-categories



TACT: Topological Algebra, Functional Analysis and Category Theory

The research team investigates mathematical structures that are important in several basic areas of mathematics like geometry, representation theory, functional analysis, differential calculus or theory of approximation. The motivation also comes from outside mathematics, from computer science or physics where some of the mathematical structures that are studied are called upon as models. By application of methods from category theory the relation between these mathematical structures is studied. The compatibility of their fundamental constructions is investigated and a general study of their representability, as well as of their function space theory is undertaken.

More specifically the theory of frames or locales uses order-theoretic notions to gain more insight in topological structures and to shed light on the use of choice principles in topology (or sometimes simply avoid them altogether).

The theory of approach spaces provides the tools for obtaining quantified results in topology and in functional analysis, extending the isometric theory of Banach spaces.

The team contributes to the development of the theory of semi-abelian categories and tensor categories.
Semi-abelian categories allow a unified setting for many important homological properties of non-abelian categories. Categories of quantum groups, of rings, of Lie-algebras and of crossed modules are typical non-abelian categories, often with a tensor structure.
Abstract tensor categories lead to interesting non-commutative spaces (operator algebras) whose analytical properties are studied in connection with the properties of the associated category. The main emphasis is on representation categories of quantum deformations of semi-simple Lie groups.
