A single self-assembled semiconductor quantum dot in a high-finesse optical microcavity - the subject of this thesis - is an interesting quantum-mechanical system for future quantum applications. For instance, this system allows trapping of an extra electron and thus can serve as a spin quantum memory,…

Mechanical metamaterials are man-made materials which derive their unusual properties from their structure rather than their composition.

From surface science towards industrial practice using high-pressure scanning tunneling microscopy.

The mission of our group is understanding how science communication works to improve the interaction between science and society. We believe better science communication can improve our society and engage many different groups with science, also improving science.

Systems with local constraints is a new finding in recent researches on complex systems. The heterogeneous spatial interactions and the temporal dependencies among those numerous units make it difficult to describe by traditional statistical physics.

It is an established fact that the Standard Model has to be extended to explain the so-called Beyond the Standard Model (BSM) phenomena: dark matter, matter-antimatter asymmetry of the Universe and neutrino flavour oscillations.

Synthetic microswimmers take an important place within the interdisciplinary field of active soft matter.

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”.

With among others a laser experiment compiled of household materials, they showed the possibilities to interest young people…

For an assignment for the course Medical Anthropology, students were asked to choose a theme related to the Covid-19 pandemic, find information and present their work in a creative way. The results are impressive.

On November 25, Dr Araceli Rojas presented her book El tiempo y la sabiduría: un calendario sagrado entre los ayöök de Oaxaca. The event took place in the Central Public Library of the State of Oaxaca, in the heart of Oaxaca City, at 7 pm.

Would you like to take a walk with a fellow student who you don’t know? That is the idea behind Walk & Talk. With this new initiative, International Studies aims to provide more opportunities for social contact.
