Abstract: We study a nonrelativistic system made of two quantum particles constrained to move on a line and a spin located at a fixed point of the line. Initially the two particles are in a maximally entangled state and the spin is down. The first particle interacts with the spin while the second particle is free, i.e., it does not interact neither with the first particle nor with the spin. We rigorously prove that there is a correlation between the state of the spin and the state of the second particle. More precisely, we show that, in a suitable scaling limit, if the first particle flips the spin, then the second particle possesses a definite momentum in the direction opposite to the spin.

We consider a pair of particles that interact in a one-dimensional setting via a delta-function potential.<n>The free particle is incident from the left with specified energy, and it may cause changes in state of the confined particle before flying away to the left or to the right.

Entanglement autodistillation from particle decays [0.0]
We show that for a spin-entangled pair of particles the entanglement of the system can increase after the decay of one particle. This unique phenomenon has no equivalent for stable particles and could be observable in top pair production at a high-energy polarized $e+ e-$r.

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.

We study theoretically repelling quantum states of two spinless particles in a one-dimensional tight-binding model. We demonstrate, that when the particles are not identical, their interaction drives nontrivial correlated two-particle states.

Two-particle topological Thouless spin pump [0.0]
We show that two particles interacting via spin exchange exhibit topological features found in one-dimensional single particle lattice models. By using the spin states as a synthetic spatial dimension, we show two particles are enough to simulate well known topological properties in condensed matter physics.

We show that non-contact friction enhances the decoherence of the moving atom. We suggest that measuring decoherence times through velocity dependence of coherences could indirectly demonstrate the existence of quantum friction.
