With the tip of a scanning tunnel microscope as a tool, atoms can be assembled into one (1D)- or two-dimensional (2D) lattices on solid material surfaces (1,2). Simultaneously their spin-resolved spectral functions can be measured one atom at a time (3,4). Combining spin-carrying transition metal or rare earth atomic lattices with different substrates such as normal metals (2,4-7),...

High frequency gravitational waves could carry unique information about the early universe and physics beyond the standard model. However, measuring these elusive signals requires dramatic technology, such as superconducting microwave cavities, which are highly efficient resonators. I will introduce a gravitational wave detector based on such a cavity and explain how it could evade standard...

Current ground-based gravitational wave observatories are limited by controls induced displacement noise at low frequencies (below 30Hz). To increase the sensitivity of current observatories and reach the desired performance of the next generation we are developing new compact and ultra precise interferometric displacement sensors, which are limited by quantum noise and make use of novel...

Quantum topology is the branch of mathematics that connects entanglement in quantum mechanics with topological entanglement in low-dimensional topology, such as the knotting, tangling, and linking of strings in 3d space. At its core lie Artin’s braid groups, algebraic structures that capture the rules of intertwining strands. These same structures underpin topological quantum computation,...

Connectives like “and” and “or” allow us to construct sentences—whether in natural language, formal logic, or programming. In classical logic, variables within these sentences can be freely copied or discarded. However, when variables represent resources—such as quantum information—that freedom is no longer appropriate. This has motivated linear logic, a resource-sensitive refinement of...

Understanding the principles of quantum gravity is undoubtedly among the most important challenges for fundamental physics in the 21st century. Modern mathematics can guide the way towards uncovering such principles, especially in the context of string theory, and at the same time receives new inspiration from physics insights into quantum gravity. I will exemplify this cross-fertilisation of...

One of the most compelling questions of string phenomenology is how to find viable inflationary models stemming from string theory. While asymptotic regions of the moduli space have been extensively explored - with limited success - little is known about inflationary dynamics in transitional, or 'penumbral', regions. In this talk, I will focus on the complex structure moduli space of Type IIB...

Despite the huge number of different consistent low-energy effective gravitational theories that arise from string theory, there appear to be ubiquitous patterns in all such theories, which encode fundamental properties of quantum gravity. In additon, unraveling such patterns often involves a fascinating interplay between physics and geometry. In this talk, we will discuss a particular...

Conformal Field Theories serve as a cornerstone in theoretical physics, playing essential roles in the study of quantum field theory, string theory, statistical systems, and holography. When these theories admit exactly marginal couplings, they organize themselves into families described by conformal manifolds—moduli spaces endowed with rich geometric structures. Understanding these spaces...

In the absence of gravity, field theories in six dimensions can be UV-completed to either Superconformal Field Theories (SCFTs) or Little String Theories (LSTs) and can be geometrically engineered from string theory. Large classes of these theories can furthermore be understood as deformations of a few "parents" through a network of Renormalisation Group flows. After reviewing some of their...
