Applications of topology to Weyl semimetals and quantum computing
This thesis covers various applications of topology in condensed matter physics and quantum information.

Spinmomentum locking in oxide interfaces and in Weyl semimetals
Electrons in a crystal lattice have properties that may differ from those of a free electron in vacuum.

Geometry and arithmetic of del Pezzo surfaces of degree 1
This thesis contains results on the arithmetic and geometry of del Pezzo surfaces of degree 1.In Chapter 1 we give the necessary background, assuming the reader is familiar with algebraic geometry.

Peculiar particles show paradoxical behavior
Theoretical physicists research a special class of particles; Weyl fermions. They have found them to exhibit paradoxical behavior, in contradiction to a thirtyyear old fundamental theory in electromagnetism. A possible application is a new kind of electronics—spintronics. Publication in Physical Review…

Three FOMProjectruimte Grants for Leiden Physics
The Leiden Institute of Physics has been awarded three out of twelve available grants from the FOM Projectruimte. Principal Investigators Milan Allan, Stefan Semrau and Carlo Beenakker all receive around 400,000 euro for their research.

Special Interest Groups
Several socalled Special Interest Groups are linked to DSRP. These groups focus on specialized topics and organize their own group meetings, talks etc. Contact the group leader if you are interested to join. It is possible to be a member of multiple groups.

Working groups at eLaw
The purpose of eLaw's Working Groups is to stimulate a productive working environment for cooperation within the Center for Law and Digital Technologies at Leiden University.

LACDR PhD group Teamsite
Every LACDR PhD candidate has access to the SharePoint teamsite of the LACDR PhD group. This site is specially and only for PhD candidates of the LACDR. We strive to collect here all relevant PhD information and to stimulate the collaboration and communication in the LACDR PhD community.

LOFAR eInfrastructure Group
The LOFAR einfrastructure group is responsible for deploying and maintaining LOFAR processing on distributed einfrastructure. A cooperation between SURFsara, Leiden University and ASTRON, the group develops software to integrate the LOFAR stack with processing pipelines. Our software can schedule…

Computer support group
The Computer Support group provides dedicated support for the computing infrastructure of Leiden Observatory

Expansions of quantum group invariants
In my research, we developed a method to distinguish knots. A knot is a mathematical depiction of the everyday knot that occurs in ropes and cords.

The Leiden Papyrology+ group
Leiden University has a rich history in the domain of Papyrology. Papyrology+, founded in 2014, is a collaboration of Leiden scholars studying (Abnormal) Hieratic, Demotic, Aramaic, Greek, Latin, Coptic, and Arabic papyri from a sociohistorical, economic and linguistic perspective.

Governance and Data Science Group
The extensive use of electronic communication channels and other devices has opened new possibilities for collecting data on human behavior. This information is sometimes openly accessible, but largely part of administrative registration systems that are not open to the broader public. The data provides…

Focus on Emotions research group
We examine the effect of social learning on emotional competence in children and adolescents with a typical or atypical development.

Group representations in Banach spaces and Banach lattices
Promotor: S.M. Verduyn Lunel, Copromotores: M.F.E. de Jeu, B. de Pagter

Beenakker Group (Theoretical Nanophysics)
Our world is shrinking, or at least our electronic devices are. From PCs to mobile phones: everything is smaller and thinner. The smaller the chip, the better it can conduct electricity and pass on information.

Intense automorphisms of finite groups
In this thesis we classify the pairs (p,G), where p is a prime number and G is a finite pgroup possessing an intense automorphism, i.e. an automorphism that sends each subgroup of G to a Gconjugate, that is nontrivial and whose order is coprime to p.

Group behaviour: one for the team
Researchers at Leiden study group behaviour. One of their findings is that when people make sacrifices for another member of their group, it is probably instinctive. Insights of this kind enable us to better understand and influence the social processes in a neighbourhood or company.

Collaboration in groups during teacher education
Collaboration is increasingly common among teachers in schools. As such, teacher education should prepare prospective teachers to effectively interact with other teachers in different types of communities or groups.

Jan Zaanen Group (Quantum Matter Theory)
The focus of our theoretical physics research is the nature of macroscopic matter that is in one or the other way still in the grip of quantum physics.

Alexey Boyarsky Group (Particle and Astroparticle Physics)
My work is motivated by the necessity to extend Standard Model of Particle Physics in order to explain three observed phenomena that this great theory fails to accommodate

Selfinterest versus group interest
People are less willing to give up an interest when in a negotiation situation than when they can do it of their own free will, as Leiden University psychologist Eric van Dijk discovered. Knowledge of this kind can be used by policy makers, for instance, to motivate people to adopt certain desirable…
