Aeppli’s scientific research is currently focused on the applications of nanotechnology and photon science to biomedicine and quantum information processing. Projects include the development of optical and microwave tools for medical diagnostics and pharmacology, where we are interested in new drug-target and antibody-antigen binding assays.
Involvement since the early days of spintronics, recognition for his work on giant magnetoresistance (CPP-GMR).Magnetic relaxation of single nanostructures.
Professor Harald Brune’s research program focuses on the exploration of the novel physical and chemical properties arising when metals shrink to the nanoscale. Starting from a detailed understanding of epitaxial growth, derived from variable temperature.
Femtosecond dynamics of Cooper pairs condensate in superconductors, melting dynamics of quantum solids, dynamics of surface electric fields in nanostructures and membranes.
Our research program focusses on the study of the effects of spin-orbit interaction (SOI) on the electronic structure of a variety of materials. Most prominent examples are topological insulators and Rashba systems where the SOI lifts the spin degeneracy, making these materials promising candidates for spintronics applications. Our experimental method of choice is spin- and angle-resolved photoemission using synchrotron radiation.

The Earth and Planetary Science Laboratory works to apply the techniques of physics and chemistry to the behavior of Earth and planetary materials in order to understand processes of planetary surfaces, mantles and cores.
At the Laboratory of Electron Spectroscopy (LSE-IPN) I run a research program focussed on strong electronic correlations in solids and at surfaces. The main research tool is angle-resolved photoemission (ARPES) with very high energy and momentum resolution.

He is working on several aspects of the problem of strongly correlated electronic systems, with current emphasis on frustrated magnetism and low-dimensional conductors, in the context of several transition metal oxides as well as organic conductors.
The research activity covers the study of atomic-scale phenomena both from the structural and dynamical point of view. The aim is to complement experiment by providing a realistic description of the mechanisms occurring on the atomic and nanometer scale.
We study mainly magnetic phenomena in correlated electron materials ranging from local spin clusters to novel superconductors. Our thrust is on combination of the powerful techniques of neutron scattering at large scale facilities with in house measurements.
