This thesis proposes multiple paths towards the development of a performance practice in Computer Music.

Materials with strongly correlated electrons show some of the most mysterious and exotic phases of quantum matter, such as unconventional superconductivity, quantum criticality and strange metal phase.

The Copenhagen interpretation of quantum mechanics states that a measurement collapses a wavefunction onto an eigenstate of the corresponding measurement operator.

A suitcase as a messenger of quantum science. That is the idea behind QuanTour, a project connecting researchers from 12 European universities. In December, the suitcase landed in Leiden. A month later, it is time to pass the baton to Copenhagen. But what happened to it in Leiden?

A world-famous light experiment from 1801 has now been carried out with sound for the first time. Research by physicists in Leiden has produced new insights that could be applied in 5G devices and the emerging field of quantum acoustics.

Atoms and molecules are the basic units of matter. If we keep dividing a bar of gold or a glass of water into smaller parts, at the end we are left with a single gold atom or a water molecule.

We are living in an information era where the amount of image and video data increases exponentially.

One of the most important correlation functions in physics, especially in cosmology, is the energy density, which describes how much energy is present at each point in spacetime due to matter fields. A key contribution to the energy density of the primordial universe comes from gravitational waves (GWs),…

Prof. Dr. Richard Gill has recently joined as a member of the Foundational Questions Institute (FQXi). FQXi is an international association of scientists who explore the foundations of physics and cosmology.

ALICE is Leiden University's newest computing miracle. The computing cluster is a first step in the development of infrastructure for computational and data-intensive research that is accessible to everyone within Leiden University and the LUMC. This includes both experienced users of high-performance…

Without electronics carrying out computational tasks our daily lives would look very different. Devices such as elevators, vending machines, turnstiles, washing machines and even traffic lights use a simple form of electronic computing to switch from state to state. But, what if power supply is not…

Kan een computer in de rechtszaal net zo goed uitspraak doen als een rechter? Hoogleraar Recht en informatica Jaap van den Herik vindt volmondig van wel. Hij legt het uit in een college van de Universiteit van Nederland.

The LIACS Media Lab has received a research grant from the worldwide leading graphics hardware company NVIDIA. The grant exists of newly developed hardware utilizing thousands of processors. LIACS researchers will use it to investigate deep learning in understanding imagery from sources such as MRI…

In January, Dr Karsten Lambers was appointed as Professor of Digital and Computational Archaeology at Leiden University's Faculty of Archaeology. With his extensive background in both archaeological research and computational sciences, the installation of Professor Lambers further strengthens this discipline…

This thesis deals with the use of sound in interactions in the context of participatory systems and data sonification. We investigate an interactive environment where participants perceive information of the data through sound elements.

What are the characteristics of impactful education for student application of inclusive design principles in design and technology programs?

At the moment, over 350.000 chemicals are registered worldwide for production and use. Their application, however, may harm human health and the environment.

PhD defence

The Leiden Institute of Advanced Computer Science congratulates alumnus Pepijn van Heiningen and the with the Technische Hochschule Köln shared PhD-student Samineh Bagheri. At the SSCI 2016 conference on computational intelligence in Athens last week, both of them won an award for the high quality of…

Using 2D materials, physics student Romme van der Kemp developed a nanochip that is extremely small ánd scalable. This is needed to make all kinds of technologies better, faster and smaller. He has been nominated for the FWN Young Talent Award 2023 for his research.

For decades, linguists have racked their brains over the question of precisely how the syntax of various languages is different. PhD candidate Martin Kroon has developed a computer system that brings us closer to finding an answer. His PhD defence is on 10 November.

Tjerk Oosterkamp of the Leiden Institute of Physics managed to do the first-ever measurement of gravity on a tiny particle - just 0.43 milligrams - where the quantum regime starts. He explains in Physics World why this is so challenging.

Spectroscopic studies on fluorescent single molecules in organic condensed matter does not only provide information about the molecule itself, but also its near environment. By suppression of phonon-induced broadening of spectral lines through cooling to low temperatures, small changes in the spectral…

The long term goal of the Biophysical Organic Chemistry/SSNMR group, headed by Prof. Huub de Groot, is to reach an understanding of structure, dynamics and functional mechanisms of membrane proteins and self-organized biological assemblies and to translate this knowledge into new concepts for nano-devices,…
