In this thesis we study quantum transport phenomena on the nanometer scale, in two classes of materials: topological insulators with induced superconductivity and graphene superlattices.

Unconventional superconductors form one of the big mysteries in physics. Among them is strontium ruthenate, which stands out as a controversial superconductor. During his PhD, Leiden physicist Kaveh Lahabi has provided new insights into the nature of superconductivity in this material, leading to a…

In this Thesis, novel charge induction mechanisms of ionic liquids are treated, tested and experimented on complex oxides, in particular cuprates.

Triplet superconductivity refers to a condensate of equal-spin Cooper pairs (pairs of electrons with equal spin).

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

Superconducting devices such as SQUIDS (Superconducting Quantum Interferometry Device) can perform ultra-sensitive measurements of magnetic fields. Leiden physicsts invented a method to 3D-print these and other superconducting devices in minutes.

NWO has granted Jan Aarts en Vadim Cheianov a Physics Projectruimte, a granting instrument for small-scale projects that propose innovative fundamental physics research that has a scientific, industrial or social urgency.

In this project innovative technology for photovoltaics cells is developed and analysis of ecological and health related risks are explicitly accounted for.

Cody Bahir defended his thesis on 1 June 2017.

In this work, we illustrate unconventional approaches towards the fabrication of edge functionalized graphene nanostructures and bidimensional architectures in polymeric and metallic supports, with an outlook towards molecular sensing devices.

From Complex Hunter-Gatherers to Early Urban Societies

High-temperature superconductivity is one of the big mysteries in physics. Milan Allan’s research group used a Josephson Scanning Tunneling Microscope to image spatial variations of superconducting particles for the first time, and published about it in the journal Nature.

Identification and characterization of components of DNA repair pathways and their role in Agrobacterium T-DNA integration and repair of CRISPR/Cas induced DSBs.

In our lab, we investigate the physics and material properties of low-dimensional systems.

From 2 to 5 September 2015, Leiden served as the stage for one of the world’s largest linguistics conferences: the Societas Linguistica Europaea (SLE) 2015 Annual Meeting. Marianne Mithun, a professor at University of California, Santa Barbara and outgoing president of the SLE, is not surprised that…

The master’s specialisation Research in Physics, Quantum Matter and Optics at Leiden University offers a thorough experience on the front line of physics research with a practical training of communicative and computer skills. The programme focuses on Condensed Matter problems, such as Molecular Electronics,…

To date it has proved very difficult to convert the promises of the miracle material graphene into practical applications. Amedeo Bellunato, PhD candidate at the Leiden Institute of Chemistry, has developed a method of cutting graphene into smaller fragments using a diamond knife. He can then construct…

How do the starchy botanical foodways reflect upon previous archaeological understandings in the northern and circum-Caribbean?

You will learn to produce solutions to current issues found where economics and public administration meet. You will analyse the ways in which social-economic policy and regulatory governance can be improved, and how to realise those improvements in the recalcitrant administrative playing field, in…

How are night spaces imagined, produced, experienced and narrated by migrant communities in Europe? This research project considers this question in eight European cities: Aarhus, Amsterdam, Berlin, Cork, Galway, Lisbon, London, Rotterdam. Authorities have historically wrestled with the issue of night-time…

The Economics & Governance specialisation of the Master in Public Administration teaches you to formulate problem-solving approaches to concrete policy issues found at the intersection between economics and public administration. This specialisation is a unique joint offering of the Department of Economics…

A collaboration between the IBL and LUMC has resulted in the discovery that the polymerase theta enzyme is essential for the integration of Agrobacterium T-DNA into the genome of plants. The finding means a break-through for the development of more efficient systems for targeted genome modification…

Erik Danen is looking at how to inhibit tumours that do not respond well to medicine – and he is making some headway. The Professor of Cancer Drug Target Discovery studies the interaction between tumour cells and their surroundings. Inaugural lecture on Friday 10 May.

Leiden physicists and chemists have managed to bring two graphene layers so close together that an electric current spontaneously jumps across. In the future this could enable scientists to study the edges of graphene and use them for sequencing DNA with a precision beyond existing technologies. Publication…

An international group of scientists, led by Leiden physicist Sense Jan van der Molen, has developed the first switchable molecular diode. You can turn this on and off through humidity. Vice versa, it is a humidity sensor at the nanoscale. Publication on 4 December in Nature Nanotechnology.

Although Ebola is a virus with significant fatality rates, we still lack effective countermeasures to battle it. To change this, Alireza Mashaghi and his colleagues from the Leiden Academic Centre for Drug Research have successfully developed an organ-on-a-chip model that imitates the most dangerous…
