Three Dimensional Quantum Nanomaterials

Introduction

Quantum nanomaterials are highly relevant for today’s society, playing a key role in existing technologies and promising revolutionary changes addressing global issues. They offer the possibility for new computing architectures and highly efficient devices.

Background

Until now, most studies of quantum nanomaterials have been two-dimensional. Extending to three dimensions results in opportunities for increased density and interconnectivity, with the potential to go beyond the physics of planar systems. This has recently been exemplified by nanomagnetism, where advances in methodologies have driven breakthroughs in our physical understanding, leading to the discovery of exotic spin textures, non-reciprocal dynamics, and curvature-induced effects.

However, the extension of a wider range of quantum nanomaterials to 3D geometries faces experimental challenges.

Project Proposal

In this ERC project, I propose to explore the physics of quantum nanomaterials in three dimensions. This will involve developing state-of-the-art experimental techniques and establishing a common experimental methodology to study the fundamental physics of 3D quantum nanomaterials.

Scientific Cases

This project will address three scientific cases:

1. 3D Antiferromagnetic Imaging: I will develop 3D antiferromagnetic imaging to explore the formation of topological textures in antiferromagnets and their current-induced dynamics.

2. Dynamics of 3D Nanomagnets: I will measure the dynamics of 3D nanomagnets, realizing non-reciprocal domain wall motion and spin waves in a low-symmetry 3D geometry.

3. 3D Superconducting Nanocircuits: I will harness new nanofabrication capabilities to explore the physics of 3D superconducting nanocircuits, achieving local control of the state, as well as exploring the behavior of superconducting vortices.

Expected Outcomes

This project will lead to advances both in experimental capabilities and in our understanding of the influence of 3D nanogeometries on the physics of quantum materials. The project will facilitate a change of paradigm for quantum nanomaterials, impacting both fundamental research and technological applications.
