Why do black holes emit thermal radiation? And how does a closed quantum system thermalize?

A plasma is an ionized gas with very low electrical resistivity. As such, magnetic field lines are 'frozen in' and move with the fluid. Magnetic field lines that are linked, knotted and tangled, cannot be undone by the fluid motions.

In this thesis, we show that we can use Shimura’s CM theory to explicitly compute the Hilbert class field of any primitive quartic CM field.

This thesis explores how electron paramagnetic resonance (EPR) spectroscopy can be used to investigate key biochemical processes.

Hoogleraar getaltheorie Manjul Bhargava heeft een Fields Medal gekregen, ook wel de ‘Nobelprijs voor de wiskunde’ genoemd. Dat is woensdag 13 augustus 2014 bekend gemaakt. Bhargava is hoogleraar in Princeton en daarnaast sinds 2010 Stieltjes hoogleraar in Leiden. 'Alles wat hij aanraakt verandert in…

Advanced UHF MRI techniques provide powerful tools for studying the zebrafish brain, an emerging model in neurological research. In this work, various MRI and localized MRS methods are optimized and employed for UHF strength for studying the zebrafish brain.

The recently introduced nature-originated deep eutectic solvents, so-called natural deep eutectic solvents (NADES) are considered as truly green solvents, which composed of natural ingredients found abundantly in organisms.

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.

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

Protein–protein complexes are formed via transient states called encounter complexes that greatly influence the formation of the stereospecific complex.

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.

In this thesis, classes of strongly interacting quantum field theories, have been studied.

Archeoloog Mike Field besteedde zijn vakantie in augustus aan de zwaarste paardenrace ter wereld, de Mongol Derby: duizend kilometer in tien dagen over de Mongoolse steppe, de postbodes van Dzjengis Khan achterna. Field werd drie keer uit het zadel geworpen maar haalde de finish.

Hoe kan complexiteitswetenschap de transformatie van inlichtingen bevorderen?

Faciliteiten waar LIBC leden gebruik van kunnen maken (in het Engels):

The genetic information of all living organisms is contained in their DNA. Cells modify the degree of DNA compaction by epigenetics, which largely determines what genes are read out and which genes are transcriptionally silent.

This dissertation is a collection of four research articles devoted to the study of Kummer theory for commutative algebraic groups.

This thesis utilises the exceptional sensitivity and resolution of LOFAR to explore the low-frequency Universe, while simultaneously advancing the telescope's capabilities to enable new scientific discovery.

This thesis is dedicated to the exploration of the primordial dark ages: unknown physics during the earliest stages of the Universe’s expansion that have not yet been directly probed by observations. Cosmic inflation is a burst of exponential expansion of space after the “Big Bang”.

In this thesis we study the landscape of gravitational models which modify GR by introducing an additional scalar degree of freedom (d.o.f.) to source Cosmic Acceleration.

By growing in a soil plants change the biotic and abiotic properties of the soil in which they grow.

This thesis studies the geometry of representation varieties and character stacks. These are spaces parametrizing the representations of a finitely generated group, typically the fundamental group of a compact manifold, into an algebraic group G.

Electrons in a crystal lattice have properties that may differ from those of a free electron in vacuum.

The challenge of achieving fast quantification in metabolomics is the presence of severe matrix effects during the MS analysis of complex samples.

De film MعLMIN van Visuele Ethnografie alumna Loes Moree wordt vertoond tijdens de komende editie van Field Recordings.

De editie van Archeologie Magazine van juni 2022 staat gedeeltelijk in het teken van Armenië. In het blad verhaalt archeobotanicus Mike Field over de bijzondere, tijdloze flora van dit Kaukasische land. Veel van de planten die voorkwamen in Pleistoceen Europa vind je tegenwoordig nog altijd in Armen…

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

The thesis mainly contributes to the characterization of Majorana fermions as they appear in the Condensed Matter context.

Een internationaal team onderzoekers onder Leidse leiding heeft negen gigantische botsingen in kaart gebracht van clusters van sterrenstelsels. De botsingen vonden zeven miljard jaar geleden plaats. De onderzoekers publiceren hun bevindingen op 2 november in het vakblad Nature Astronomy.
