Unconventional superconductivity arises at the border between the strong coupling regime with local magnetic moments and the weak coupling regime with itinerant electrons, and stems from the physics of criticality that dissects the two. Unveiling the nature of the quasiparticles close to quantum criticality is fundamental to understand the phase diagram of quantum materials. Here, using resonant inelastic x-ray scattering (RIXS) and $${\rm{Fe}}-{{\rm{K}}}_{\beta }$$Fe−Kβ emission spectroscopy… Expand

Tuning spin excitations in magnetic films by confinement
The thickness dependence of the dispersion of spin waves in mesoscopic iron films is measured and found to be renormalized in the out-of-plane direction as the thickness is reduced, highlighting the effects of mesoscopic scaling on spin dynamics and identifying thickness as a knob for fine tuning and controlling magnetic properties.

Anisotropic softening of magnetic excitations along the nodal direction in superconducting cuprates.
The high-Tc cuprate superconductors are close to antiferromagnetic order and excitation spectra composed of particle-hole excitations suggest that superconductivity emerges from a coherent treatment of electronic spin and charge in the form of quasiparticles with very strong magnetic correlations.

Persistent high-energy spin excitations in iron-pnictide superconductors.
The persistence of spin excitations well into the superconducting phase suggests that the spin fluctuations in Fe-pnictide superconductors originate from a distinctly correlated spin state, and connects Fe pnictides to cuprates, for which, in spite of fundamental electronic structure differences, similar paramagnons are present.
