In this talk, I will briefly review the physics of two-dimensional vortex lattices in thin superconducting films. By exploring the interplay between magnetic field, thermal fluctuations and disorder, I will provide a short overview of the different glassy phases which...

Fractional Chern insulators (FCIs) are the lattice equivalent of the fractional quantum Hall effect, whereby the intrinsic properties of the lattice provide the necessary ingredients for the emergence of this strongly correlated phase. Their existence was first...

We are a few years into the “nickel age of superconductivity” now. In this presentation I will review what we know so far and what open questions remain to be answered. I will cover both square-planar nickelates and octahedral nickelates and compare to what we have...

Strain engineering is an effective approach to tune the electronic properties of materials by applying mechanical deformation to their lattice. Conventional straining methods for 3D materials, such as epitaxial growth on substrates with lattice mismatch, dielectric...

Over the last 20 years, a lot of progress has been made in the realisation of 2D arrangements of magnetic islands. The moment of each island must point along a local axis, and the system can be described by interacting Ising spins. If the magnetic moments are parallel...

Antiferromagnetic conductors with suitably broken spatial symmetries host spin-polarized bands, which lead to transport phenomena commonly observed in metallic ferromagnets. In bulk materials, it is the given crystalline structure that determines whether symmetries...

Changing the properties of materials on demand is crucial both for understanding the conditions which allow for the appearance of emergent order and for generating new functionalities. Using laser light for this purpose is a particularly interesting approach: It...

On conventional computers, the performance of AI models is limited by the data transfer between the memory and the processor. Compute-in-Memory architectures offer a new paradigm: Vector-Matrix Multiplications may be performed by a voltage drop through a matrix of...

The translational symmetry of the ionic potential in a crystal results in a periodic electronic structure in momentum space. Analogously, the periodic electric field of an intense light pulse can create replica of electronic states. These so-called Floquet state are...

I will illustrate the paradigm of computational materials discovery, as applied to the case of two-dimensional and one-dimensional materials.First, a high-throughput study of experimentally-known inorganic compounds identifies promising candidates that could be...
