A particular strength of ultracold quantum gases is the range of versatile detection methods
that are available. As they are based on atom–light interactions, the whole quantum optics …

Phase transitions are driven by collective fluctuations of a system's constituents that emerge
at a critical point. This mechanism has been extensively explored for classical and quantum …

The Pauli exclusion principle is a fundamental law underpinning the structure of matter.
Because of their antisymmetric wave function, no two fermions can occupy the same …

On the fundamental level, quantum fluctuations or entanglement lead to complex dynamical
behaviour in many-body systems for which a description as emergent phenomena can be …

Bell correlations are a foundational demonstration of how quantum entanglement
contradicts the classical notion of local realism. Rigorous validation of quantum nonlocality …

The control and manipulation of quantum systems without excitation are challenging, due to
the complexities in fully modeling such systems accurately and the difficulties in controlling …

Many-body interference between indistinguishable particles can give rise to strong
correlations rooted in quantum statistics. We study such Hanbury Brown–Twiss-type …

Ghost imaging is a quantum optics technique that uses correlations between two beams to
reconstruct an image from photons that do not interact with the object being imaged. While …

We propose to simulate bosonic pair creation using large arrays of long-lived dipoles with
multilevel internal structure coupled to an undriven optical cavity. Entanglement between the …

Engineering pairs of massive particles that are simultaneously correlated in their external
and internal degrees of freedom is a major challenge, yet essential for advancing …
