This thesis is concerned with the constitution of chiral responsive matrix assemblies that may undergo light-driven conformational changes and self-select vibrations to develop vibronic states for driving semi-classical coherent transfer with nearly 100% yield in a lossless NCAP process.

With a pioneering project like the quantum computer, it’s a good idea not to place all your bets on a single horse. In Leiden’s Quantum Optics research group, instead of working on a Majorana-based qubit, people are working on a qubit based on an ‘artificial atom’. If that becomes the basis of the quantum…

The aim of this facility is to accelerate biomedical research by providing access to advanced light and electron microscopy and by sharing expertise about sample preparation, imaging modalities, data storage and image analysis.

This study stresses the importance of investigating vitamin D deficiency in every community to better understand the deteriorating effect that sociocultural practices may have had on health.

The International Day of Light (IDL) celebrates the ubiquitous role light has in our lives. From Argentina to South Africa, Japan and Pakistan, several events have taken place across all continents on May 16. The date is a token for people around the globe to connect with the importance of light in…

LIACS is a partner in the EU Erasmus+ Curriculum Development for the Asian education system. The knowledge available in the field of Data Science and Artificial Intelligence education will be shared and adapted for the Asian market.

Metal-containing molecules combine geometrical features and a reactivity that are inherently different from that of organic molecules. My research focuses on light-activatable metal-based anticancer drugs and metal-functionalized liposomes. Light is a very selective way to activate photosensitive drugs…

In deep reinforcement learning, searching and learning techniques are two important components. They can be used independently and in combination to deal with different problems in AI, and have achieved impressive results in game playing and robotics. These results have inspired research into artificial…

On the 23rd of January, Anastasiia Ionova successfully defended her doctoral thesis and graduated. The Leiden University Centre for Linguistics congratulates Anastasiia on this achievement.

Research in the van Exter lab focuses on quantum aspects of light and light-matter interaction. One of our long-term goals is to develop a reliable quantum memory, based on a single emitter in an open micro cavity.

Light-Harvesting Complex II (LHCII) is responsible for light absorption and excitation energy transfer in plants and photosynthetic algae, while in high light it undergoes conformational changes by which it quenches excitations to prevent photodamage.

Farmers on the outskirts of Nairobi National Park protect their livestock using flashing lights on top of the animal enclosures. This system keeps lions away at night. Leiden research has shown that the method is both simple and effective. Publication in PLOS ONE.

This project addresses the occurrence of political and ideological biased crimes in light of the recent migration influx in European countries.

In this article Vanessa Newby discusses how the ANZUS states of United States, Australia, and New Zealand that sit on the fringes of the Asia-Pacific, are increasingly using their armed forces to deliver Humanitarian Aid and Disaster Response (HADR) as a way of engaging with the region.

On 25 September, lights throughout Leiden will be turned off for the Seeing Stars event. What makes the urban night so special? We asked university lecturer Sara Brandellero, who researches cities, night and migration.
