Cavity-enhanced fractional quantum Hall phases and cavity-modified spin splittings

Juin 2, 2025 | MPQ, THEORIE

A collaboration between the Equipe Théorie at MPQ and scientists from ETH Zurich and the Flatiron Institute has demonstrated, both theoretically and experimentally, that giant vacuum fields confined in a split-ring resonator cavity can profoundly alter...

Unravelling the nonlinear generation of designer vortices with dielectric metasurfaces

Jan 23, 2025 | DON, MPQ

Researchers from the DON team have demonstrated and analyzed the generation of high-purity second-harmonic vortices with dielectric metasurfaces. These results are published in Light: Science and Applications. Vortex beams are currently drawing a great deal of...

Thermal stability of high-entropy nanoalloys: reality or chimera?

Jan 11, 2025 | MEANS, MPQ

By studying at the atomic scale the thermal behavior of nanoparticles composed of gold, cobalt, copper, nickel and platinum, scientists have revealed that the stability of these so-called high-entropy nanoalloys is much lower than expected, as gold and copper...

Emergent quantum phase transition in superconducting circuits

Juil 8, 2024 | MPQ, THEORIE

The THEORIE team has recently published a significant theoretical study in Nature Communications on the topic of quantum critical phenomena. This research addresses a current debate that questions the traditional understanding of dissipative quantum phase transitions...

Probing and manipulating the superconducting state of NbSe2 in the 2D limit

Juin 22, 2024 | PostDoc

Context:. The dynamics of superconductors (SC) driven out-of-equilibrium is governed by their collective mode spectrum, and in particular the SC amplitude mode which is an analog of the Higgs mode in high-energy physics [1]. In many materials the coexistence of SC...
