- Abstract summary: We investigate the spin entanglement in few-nucleon scattering processes involving nucleons and deuterons.
In contrast to proton-neutron scattering, no universal low-energy features are evident in the spin entanglement in neutron-deuteron, proton-deuteron, and deuteron-deuteron scattering.

- Abstract: We investigate the spin entanglement in few-nucleon scattering processes
involving nucleons and deuterons. For this purpose, we consider the
entanglement power introduced by Beane et al. We analyze different entanglement
entropies as a basis to define the entanglement power of the strong interaction
and calculate the corresponding entanglement powers for proton-neutron,
neutron-deuteron, proton-deuteron, and deuteron-deuteron scattering. For the
latter two processes, we also take into account the modification from the
Coulomb interaction. In contrast to proton-neutron scattering, no universal
low-energy features are evident in the spin entanglement in neutron-deuteron,
proton-deuteron, and deuteron-deuteron scattering.

Changes in electron dynamics within the gas target have a negligible effect on dynamics of neutrons and protons.
We propose a theoretical approach to obtain these parameters from the momentum spectrum of ionized electrons within a hydrogen atomic gas target.

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.

We show that the orientation of the angular momentum transferred from the laser field to the rotons, is dictated by the centrifuge.
The observed decay of the coherent Raman signal suggests that the decoherence is governed by the scattering on thermal rotons and phonons.

hyperfine interactions [49.1574468325115]
This article demonstrates that the hyperfine coupling, which consists of Fermi contact and dipolar interactions, can mediate the application of spin-orbit torques acting on nuclear spins.
The reactions to the equilibrium and nonequilibrium components of the spin density is a torque on the nucleus with field-like and damping-like components.
This nuclear spin-orbit torque is a step toward stabilizing and controlling nuclear magnetic momenta, in magnitude and direction, and realizing nuclear spintronics.

We study entanglement entropies between the single-particle states of the hole space and its complement in nuclear systems.
We show that entanglement entropies are proportional to the particle number fluctuation and the depletion number of the hole space for sufficiently weak interactions.

Low-density neutron matter is characterized by the formation of Cooper pairs and the onset of superfluidity.
We model this density regime by capitalizing on the expressivity of the hidden-nucleon neural-network quantum states combined with variational Monte Carlo and reconfiguration techniques.

bath [55.41644538483948]
Spin-bath interactions are strongly anisotropic, and rapid physical rotation has long been used in solid-state nuclear magnetic resonance.
We show that the interaction between electron spins of nitrogen-vacancy centers and a bath of $13$C nuclear spins introduces decoherence into the system.
Our findings offer new insights into the use of physical rotation for quantum control with implications for quantum systems having motional and rotational degrees of freedom that are not fixed.

Twisted neutrons have definite quantized values of an angular momentum projection along the direction of propagation.

We show that quantum entanglement between causally separated regions of a nucleon in antineutrino-nucleon scattering manifests itself as a thermal component in the resulting pion momentum distribution.
For antineutrino scattering coherently from the (carbon) nucleus as a whole, this thermal component is absent, as expected by our quantum entanglement thermalization proposition.
