Gauge theories constitute the basis of the Standard Model and provide useful descriptions of
various phenomena in condensed matter. Realizing gauge theories on tunable tabletop …

Atomic gases confined in curved geometries are characterized by distinctive features that
are absent in their flat counterparts, such as periodic boundaries, local curvature and …

Gravity simulators are laboratory systems in which small excitations such as sound or
surface waves, behave as fields propagating on a curved spacetime geometry. The analogy …

In a multi-fold universe, gravity emerges from entanglement through the multi-fold
mechanisms. As a result, gravity-like effects appear in between entangled particles, whether …

We investigate signal propagation in a quantum field simulator of the Klein–Gordon model
realized by two strongly coupled parallel one-dimensional quasi-condensates. By …

Explicitly covariant analytical expressions are derived that describe the boundaries of
shadows cast by massive particles scattered by a gravitating object. This covers scenarios …

In this study, we investigate the influence of Hawking decoherence on the quantum
correlations of Dirac fields between Alice and Bob. Initially, they share a Gisin state near the …

Experimental platforms based on ultracold atomic gases have significantly advanced the
quantum simulation of complex systems, yet the exploration of phenomena driven by long …

Quantum simulators offer powerful means to investigate strongly correlated quantum matter.
However, interpreting measurement outcomes in such systems poses significant challenges …

We present a general class of entanglement criteria for continuous variable systems. Our
criteria are based on the Husimi Q distribution and allow for optimization over the set of all …
