• Title: Detecting circular Unruh effect with quantum entanglement
• Authors: Yuebing Zhou, Jiawei Hu, Hongwei Yu
• Abstract summary: We show that the state of a quantum system composed of two atoms in circular motion in vacuum can be entangled when the angular velocity and the radius of the orbit are appropriate. The entanglement as a result of centripetal acceleration is initial-state independent and can be viewed as a manifestation of the circular version of the Unruh effect.

• Abstract: We show that the asymptotic state of a quantum system composed of two atoms in circular motion in vacuum can be entangled when the angular velocity and the radius of the orbit are appropriate. The asymptotic entanglement as a result of centripetal acceleration is initial-state independent and can be viewed as a manifestation of the circular version of the Unruh effect. Based on this phenomenon, we propose an optomechanical setup to detect the circular Unruh effect with the state-of-the-art technologies.

  We investigate the dynamics of ultra-cold atoms confined in a toroidal trap with a ring-lattice along the azimuth angle. In the presence of external rotation of small angular acceleration, or prescribed linear chirp between the two beams, the measured angular momentum of trapped atoms displays a specific periodic behaviour in time.

  We study the backreaction effects of quantum field processes in Dynamical Casimir effect (DCE) and cosmological particle creation (CPC) We find that for 1+1D, the only quantum field effect due to the trace anomaly tends to accelerate the contraction of the ring over and above that due to the attractive force in the static Casimir effect. Our findings comply with what is known as the quantum Lenz law, found in cosmological backreaction problems.

• Coulomb problem for classical spinning particle [0.0]
  We consider a weakly relativistic charged particle with an arbitrary spin in central potential $e/r$ in terms of classical mechanics. We show that the spin-orbital interaction causes the precession of the plane of orbit around the vector of total angular momentum. The effective potential for in-plane motion is central, with the corrections to Coulomb terms coming from spin-orbital interaction.

We show in exact diagonalization simulations of the one-dimensional $t-J$ model that the spinons start to populate previously unoccupied states in an effective band structure. The dependence of the spectral function on the time after the pump pulse reveals collective interactions among spinons.

  We show that the Zitterbewegung effect manifests itself as a series of quantum beats of the particle density in the long-time limit. We also find a time-domain where the particle density of the point source is governed by the propagation of a main wavefront. The relative positions of these wavefronts are used to investigate the time-delay of quantum waves in the Klein-tunneling regime.
