• Authors: Daisuke Miki, Akira Matsumura, and Kazuhiro Yamamoto
• Abstract summary: We analyze the dynamics of a gravity-induced entanglement for N massive particles. As the particle number increases, the specific particle pair decoheres more easily due to the gravitational interaction with other particles. We also discuss the entanglement dynamics of initially entangled particles, which exemplify the monogamy of the gravity-induced entanglement.

• Abstract: We analyze the dynamics of a gravity-induced entanglement for N massive particles. Considering the linear configuration of these particles, we investigate the entanglement between a specific pair of particles under the influence of the gravitational interaction between the massive particles. As the particle number increases, the specific particle pair decoheres more easily due to the gravitational interaction with other particles. The time scale of the gravity-induced decoherence is analytically determined. We also discuss the entanglement dynamics of initially entangled particles, which exemplify the monogamy of the gravity-induced entanglement.

• Quantumness of gravitational field: A perspective on monogamy relation [0.0]
  The purpose of this study is to deepen our understanding of the phenomenon of quantum superposition of gravitational fields. We consider a trade-off relation of entanglement in a tripartite system consisting of two massive particles and a gravitational field that may be entangled with each other. Our results may help understand the relationship between the quantization of the gravitational field and the meaning of the quantum superposition of the gravitational field.

  We study the large-scale dynamics of charged particles in a rapidly oscillating field and formulate its classical and quantum effective theory description. Remarkably, the action models the effects of general relativity on the motion of nonrelativistic particles, with the values of the emergent curvature and speed of light determined by the field spatial distribution and frequency.

  Quasiparticles are emergent excitations of matter that underlie much of our understanding of quantum many-body systems. We take advantage of the clean setting of homogeneous quantum gases and fast radio-frequency control to manipulate Fermi polarons. We measure the decay rate and the quasiparticle residue of the driven polaron from the Rabi oscillations between the two internal states.

• Intrinsic quantum dynamics of particles in brane gravity [0.0]
  We show that the stability of particle trajectories on the brane gives us the Bohr--Sommerfeld quantization condition. The particle's motion along the extra dimension allows us to formulate a geometrical version of the uncertainty principle. We show that the particle's motion along the extra dimension yields a quantized energy spectrum for bound states.

• Effects of photon field on entanglement generation in charged particles [0.0]
  We analyze the entanglement generation between two charged particles coupled to a photon field. It is observed that the entanglement is suppressed by the decoherence due to the vacuum fluctuations of the photon field. The similar structures between the gravity theory and electromagnetic theory suggests that a similar feature may be observed in the entanglement generation by quantum gravitational radiation.

  We show the emergence and dynamics of intra-particle entanglement in Dirac fermions. The entanglement is a complex dynamic quantity but is generally large, independent of the initial state. These features are also expected to impact entanglement between pairs of particles, and may be detectable in experiments that combine Cooper pair splitting with nonlocal measurements of spin-spin correlation in mesoscopic devices based on Dirac materials.
