Summary: This paper reports the first experimental verification of the area law of mutual information in quantum field theory, a fundamental feature of field theories with a gapped Hamiltonian. This work is a major step toward measuring entanglement in extended quantum field simulators.

Summary: This paper studies the dynamics of correlations propagating as fronts—located on the light-cone—and explains their curvature, reflection, and recurrences through theoretical modeling based on the geodesics of the simulated geometry. The work introduces a versatile platform for detailed studies of quantum field theories in inhomogeneous spacetime.

Summary: This paper presents a novel method for designing arbitrary one-dimensional potentials on an atom chip. We built and implemented an optical setup based on a digital micromirror device to combine optical dipole traps with the magnetic trap produced by the atom chip. This major advancement enabled us to realize static mand dynamic trapping potentials to investigate
