Flat optics: structuring light with metasurfaces (Prof. F. Capasso)

Patterning surfaces with subwavelength spaced metallo-dielectric features (metasurfaces) allows one to generate complex 3D and 2D wavefronts by locally controlling the amplitude, phase and polarization of the scattered light. [more]

Developing Infrared Biofluid Diagnostics (Dr. M. Baker)

Spectroscopic analysis allows for the label-free objective classification of biological material on the molecular scale. This technique has been applied to histology, cytology and surgical pathology and can detect subtle changes in the proteome and metabolome. [more]

Experiments testing macroscopic quantum superpositions must be slow (Dr. A. Mari)

We consider a thought experiment where the preparation of a macroscopically massive or charged particle in a quantum superposition and the associated dynamics of a distant test particle apparently allow for superluminal communication. [more]

Natural orbitals of ultracold many-body systems: from experimental reconstruction to correlation analysis in coordinate and energy space (S. Krönke)

Deep insights into the structure of a many-body state can often be inferred from its natural orbitals (eigenvectors of the reduced one-body density operator) and their populations. [more]

Matrix Product States and the Fractional Quantum Hall Effect (N. Regnault)

The fractional quantum Hall effect is the most celebrate example of a two-dimensional phase that exhibits intrinsic topological order. [more]
