• Abstract summary: We investigate how entanglement affects the evolution of the particles using a modified version of the shutter quantum model. We derive a transient concurrence to momentum-space entanglement, and show that modulates the interference correlation of the joint probability density. We derive analytical expressions that reveal a direct connection between entanglement and the characteristic oscillations of the Hanbury-Brown and Twiss effect.

• Abstract: Transient dynamics of copropagating entangled bosons and fermions remains an unexplored aspect of quantum mechanics. We investigate how entanglement affects the spatiotemporal evolution of the particles using a modified version of the quantum shutter model. We derive a transient concurrence to quantify momentum-space entanglement, and show that it modulates the interference correlation of the joint probability density, allowing us to visualize the active regions where probabilistic bunching and antibunching phenomena emerge. Furthermore, we derive analytical expressions that reveal a direct connection between entanglement and the characteristic oscillations of the Hanbury-Brown and Twiss effect, highlighting the modulation of the phenomenon by quantum concurrence.

  We consider a two-dimensional tight-binding model that interacts with a background of classical spins in thermal equilibrium. To capture the salient features of the classical transition, we focus on the strong coupling limit. We provide evidence that the classical phase transition might induce a delocalization-localization transition in the quantum system at certain energies.

  Quantum interference can terminate energy growth in a continually kicked system, via a single-particle ergodicity-breaking mechanism known as dynamical localization. We report the experimental realization of a tunably-interacting kicked quantum rotor ensemble using a Bose-Einstein condensate in a pulsed optical lattice. Results quantitatively elucidate the dynamical transition to many-body quantum chaos, advance our understanding of quantum anomalous diffusion, and delimit some possibilities for protecting quantum information in interacting systems.

  Hong-Ou-Mandel (HOM) effect can lead to a perfect suppression of two-particle coincidences between the output ports of a balanced beam splitter. In this work, we demonstrate experimentally that the two-particle coincidence statistics of two bosons can instead be seamlessly tuned to substantial enhancement. Our findings reveal a new approach to harnessing non-Hermitian settings for the manipulation of multi-particle quantum states.

  We report observation of quasiparticle pair-production and characterize quantum entanglement created by a modulational instability in an atomic superfluid. By quenching the atomic interaction to attractive and then back to weakly repulsive, we produce correlated quasiparticles. We observe large amplitude growth in the power spectrum and subsequent coherent oscillations in a wide spatial frequency band within our resolution limit.
