- Plasmonic metamaterial time crystalFollowing the funding of the QUANTUM2DTMD project in 2023, the teams involved from MPQ, LSI, and CdF recently published an article in Nature. Spatial photonic crystals (SPCs) are unique structures for light–matter interactions because they achieve a large and spatially periodic dielectric contrast on wavelength scales. Their temporal analogues, photonic time crystals (PTCs), promise similar… Read more: Plasmonic metamaterial time crystal
- Non-Gaussian statistics of the order parameter across a phase transitionThe Helium on networks team at LCF recently published an article in Nature. Second-order phase transitions are characterized by critical scaling and universality. The singular behaviour of thermodynamic quantities at the transition, in particular, is determined by critical exponents of the universality class of the transition. However, critical properties are also characterized by the probability… Read more: Non-Gaussian statistics of the order parameter across a phase transition

The Fermi Gas team at Laboratoire Kastler Brossel recently published an article in Physical Review Letter. Atom-based quantum simulators offer a unique platform that enables the imaging of each particle in a many-body system. Until now, however, this capability has been limited to quantum systems in discretized space such as optical lattices and tweezers, where… Read more: Quantum Gas Microscopy of Fermions in the Continuum - In-situ Imaging of a Single-Atom Wave Packet in Continuous Space
The Fermi Gas team at LKB recently published an article in the journal Physical Review Letters. The authors: We report on the imaging of the in situ spatial distribution of deterministically prepared single-atom wave packets as they expand in a plane, finding excellent agreement with the scaling dynamics predicted by the Schrödinger equation. Our measurement provides a direct… Read more: In-situ Imaging of a Single-Atom Wave Packet in Continuous Space - Sub-MHz homogeneous linewidth in epitaxial Y2O3: Eu3+ thin film on silicon
