In the traditional theory of linear elasticity, superposition dictates that the response of a material does not depend on the sequence of the applied mechanical actuations.

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

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.

Detecting nanoscopic objects plays an important role in nanoscience in particular, in the rapidly growing field of nanobiology. The forebear to modern super-resolution microscopy for single molecule investigation, is fluorescence microscopy.

This thesis covers various applications of topology in condensed matter physics and quantum information.

In this work the reconstruction of a tau neutrino signal in the KM3NeT detector is discussed.

This thesis explores interfacial conductance and electric field-effects in LaAlO3/SrTiO3 heterostructures.

The main focus of this thesis is the behaviour of two-dimensional materials, namely (anti)-ferromagnetic materials in the first two chapters, which show topological phases, and energetic square ice in the third and fourth chapter.

Op 23 en 24 november vond op het Europees Universitair Instituut in Florence een bijeenkomst plaats ter gelegenheid van het 25 jarig bestaan van de Ruimte van Vrijheid, Veiligheid en Recht. Dit is het beleidsterrein waarbinnen de Europese Unie zich bezighoudt met Justitie en Binnenlandse Zaken.

What are the pressing issues of our time, and how can different disciplines come together to address them? Studium Generale and Leiden University College (LUC) present the Global Challenges series: events that bring together researchers from LUC and experts from other disciplines to tackle a shared…

Woensdag 6 april nam Willemien den Ouden afscheid als Dean van de Honours Academy met een debat over referenda in de Europese Unie. Niesco Dubbelboer (initiatiefnemer Wet Raadgevend Referendum), Chris Aalberts (politiek journalist) en Wim Voermans (hoogleraar Staats- en Bestuursrecht) gingen met elkaar…

Erik Zürcher (1928 – 2008) geldt nog altijd als gezaghebbende bron in het onderzoek naar Chinees boeddhisme. Een nieuwe bundel met zijn publicaties is aanleiding voor een internationaal boeddhisme-congres in Leiden. Prinses Beatrix, die hem goed kende, is aanwezig bij de opening.

This thesis presents the results of a study on the interfaces of insulating oxides with and without the insertion of a magnetic layer.

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.

This dissertation revolves around the design and implementation of novel instrumentation and related measurement techniques, at the single molecule level, for use in biophysical research. Chapter 1 presents an introduction to the field of fluorescence-based single molecule measurements. In particular,…

Early time-resolved experiments by Frauenfelder on the ensemble of the kinetic rebinding of CO to myoglobin molecules resulted in a stretched exponential relaxa-tion due to a very large spread of the reaction rates of individual molecules.

This thesis is a collection of experimental attempts to enhance photoluminescence of fluorescent molecules and quantum dots with single gold nanorods (GNRs) and relevant applications.

In human cells, a meter-long DNA is condensed inside a micrometer-sized cell nucleus. Simultaneously, the genetic code must remain accessible for its replication and transcription to functional proteins.

Graphene nanoribbons (GNRs) are used as a current carrying substrate in investigation of current-induced forces in a low-temperature STM (chapter 2).

This dissertation is an experimental study of laser-generated, atmospheric pressure, transient toroidal helium plasmas.

Scattering of light in the presence of nano-structured materials, i.e. with features in the order of the wavelength of the light or smaller, reveals details of how light interacts with matter at the nanoscale.

DNA carries various forms of information. Out of these forms of information the most well-known is classical genetic information.

In this thesis, we study systems of electrons in which strong correlations give rise to emergent exotic physics.

Mechanical metamaterials are carefully engineered materials whose properties are controlled by their structure, not by their composition, which allows using metamaterials to study and control physical effects in detail⁠.

Single-molecule spectroscopy has become a powerful method for using organic fluorescent molecules in numerous applications.
