Magnetic imaging provides invaluable insights into material properties that are not accessible via bulk measurements or conventional imaging. To image vdW magnets in the 2D limit, nanometer-scale spatial resolution and the sensitivity to resolve single atomic layers...

The desire to probe and control individual quantum systems has driven significant scientific and engineering advances in quantum coherent nanoscience. Meanwhile, single atoms and molecules on surfaces have been extensively studied in search of novel electronic and...

In this flat club I will first introduce altermagnets, a new class of magnetic systems where opposite spin sublattices are connected by symmetries that enforce a vanishing net magnetization (like in antiferromagnets) but still allow for a finite spin-splitting of...

Controlling how light propagates and is confined on nanometre scales is a central challenge in both fundamental photonics research and the development of nanoscale optical technologies. Strong progress in this area has come from using crystal anisotropy to guide...

Anomalous gating effects-such as gate ineffectiveness and pronounced hysteresis-have been observed in graphene-based systems encapsulated in boron nitride (BN) and linked to a possible ferroelectric state. However, their origin, stability, and reproducibility remain...

As predicted by E. Wigner in 1934, the long-range Coulomb interaction between electrons can lead to a phase transition, when the density becomes very low, from a (quantum) liquid or gas phase to a crystallized phase of electrons, now called a Wigner crystal. In three...

Hybridizing superconductivity with the quantum Hall effects has major potential for designing novel circuits capable of inducing and manipulating non-Abelian states. In this talk I will present our recent results on quantum Hall Josephson junctions based on graphene...

Liquids are traditionally described within classical physics, whereas solids require the tools of quantum mechanics. I will discuss how in nanoscale systems, this distinction no longer holds. The dynamics of liquids confined to nanometer-scale channels can couple to...

Resonant inelastic x-ray scattering (RIXS) allows to study electronic and magnetic excitations and their momentum and energy dependencies. For example, the absence of dd excitations at the interfaces of KTaO3 films suggests a deficiency of localized Ta 5d electrons...
