We are a dynamic research group at the Leiden Institute of Physics. Our aim is to explore and understand quantum materials, including strange metals, high-temperature superconductors, and quantum critical electron matter.

Milan Allan has received the Bryan R. Coles Prize at the International Conference on Strongly Correlated Electron Systems (SCES) in Prague.

On February 21st, Maria Vasile, one of the PhD students of the project participated to several events organized in Milan by the University of Milano-Bicocca for the celebration of the World Anthropology Day.

On 23 March 2016, Dr. Nelleke Koffeman, Assistant Professor at the Europa Instituut of Leiden Law School, taught at the University of Milan (Italy) at the invitation of Dr. Chiara Ragni.

On 2 November 2023, Jorrit Rijpma spoke at a workshop organised by the State University of Milan on a preliminary reference from an Italian court.

For a long time, in the United States ‘Schmoozes’ have been organized. These small-scale meetings offer the opportunity to informally discuss important themes. On 12 and 13 October, the first European Schmooze took place in Milan. The topic was ‘Economic Inequality as a Global Constitutional Challenge’.…

On 22 June, Professor Haentjens held a lecture at the University of Milan. He was invited to speak on the topic of the applicable law to the assignment of claims.

Physicist Milan Allan will build an instrument that will bring superconductivity research further. He has been awarded an ERC Consolidator Grant of 2 million euros over the next five years. With his PairNoise programme he aims to detect paired electrons as they occur just above the temperature at which…

Cities in Europe house an increasingly diverse population with roots in many different parts of the world. They have also seen the growth of anti-immigrant sentiments and new forms of nationalism. Who belongs to Europe and what such belonging entails is heavily debated. What comes out of this paradoxical…

Over time, the temperature in all buildings will be regulated in a sustainable manner. In this way, using gas will not be necessary anymore.

The Sun and all the stars in the night sky reside in the Milky Way galaxy. In the at-rest reference frame of the Galaxy, typical stars travel with velocities of about 100-200 kilometres per second.

Astronomer and Marxist Anton Pannekoek was a remarkable figure. This book aims to study the connections between his life as a socialist theorist and as a pioneering scientist through the prism of Pannekoek's biography.

In this thesis we use Josephson and noise scanning tunneling microscopy for the study of conventional, unconventional (iron-based) and disordered superconductors. On the one hand, Josephson scanning tunneling microscopy allows us to directly visualize the superfluid density with high spatial resolut…

In condensed matter systems electron-electron interactions, negligible in everyday metals, can dramatically alter the electronic behavior of the system. Examples of such altered behavior include high-temperature superconductivity and modulation of the electron density.

Natascha van der Zwan, Assistant Professor at Leiden Univeristy, together with two other authors, wrote a book that explored some of the ways coronavirus is impacting the global capitalist system – and how this could change for better and for worse.

On 12 March, Frederik Heitmüller defended the thesis 'Combatting tax avoidance, the OECD way? The impact of the BEPS Project on developing and emerging countries’ approach to international tax avoidance'. The doctoral research was supervised by Madeleine Hosli and Irma Mosquera Valderrama.

This book is about the workings of networks of the mobile in Africa, a continent usually associated with the ‘global shadows’ of the world.

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 Common Market Law Review has an internationally composed Editorial Board and Advisory Board.

Isabel van Vledder and Dieuwertje van der Vlugt, 2 astronomy students from Leiden University, have mapped the entire Milky Way galaxy in dwarf stars for the first time. This result is the most comprehensive model ever for the distribution of these stars. The findings appear in a new paper in Monthly…

On 29 april 2020, Beth Van Schaack defended her thesis 'Imagining Justice for Syria: Water Always Finds Its Way'. The doctoral research was supervised by Prof. C. Stahn.

Research groups in the Quantum Matter & Optics programme investigate electronic properties of matter and light-matter interactions with emphasis on quantum information.

This edited publication aims at reflecting on the future of discussions on the applicability of international law to States’ use of ICTs in the context of highly politicised discussions at the multilateral level and offering practical suggestions for the European Union to pursue its objectives in this…

An overview of awards and prizes granted to our staff and students in 2017, as well as special appointments and royal distinctions.

Om de weg te vinden letten sommige mensen op de omgeving, anderen onthouden waar ze links of rechts af moeten slaan. Mensen met Niet Aangeboren Hersenletsel (NAH) rapporteren navigatieproblemen. Om opnieuw te leren navigeren heeft neurowetenschapper Milan van der Kuil als revalidatietherapie een serious…

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.

Supervisor: S.F. Portegies Zwart Co-Supervisor: A.G.A. Brown

In this project, researchers from computer science, law, psychology, and public administration research in practice how artificial intelligence (AI) can be leveraged to make decision-making in the security domain more effective, while also keeping it safe and accountable.

Chenyu Cheng defended her thesis on 6 April 2017.

Nanoparticles are widely used, but their effect on the environment is unclear because they are hard to track. Leiden physicists have developed a new method to detect conducting nanoparticles. Aquiles Carattino successfully defended his PhD thesis on the subject.
