Abstract: The Wigner rotation of quantum particles with spin is one of the fascinating consequences of interplay between special relativity and quantum mechanics. In this paper we show that a direct experimental verification of Wigner's rotation is in principle accessible in the regime of non-relativistic velocities at $\sim 10^3$ m/s for massive spin-$1/2$ particles. We discuss how the experiment could be carried out in a laboratory using cold neutrons. The measurement at non-relativistic velocities becomes possible through letting neutrons propagate for a sufficiently long time because Wigner rotation is a cumulative effect.

We show how an embedded spin affects the rotation of rapidly revolving quantum rotors due to the Einstein-de Haas and Barnett effects. This will open the door for future exploitations of quantum spin rotors for superposition experiments with massive objects.

We investigate the transition rates of a centripetally accelerated atom interacting with electromagnetic vacuum fluctuations inside a high-quality cavity. Our findings reveal that the emission and excitation rates can be extensively manipulated by adjusting the cavity's normal mode frequency and the rotational angular velocity.

Levitated diamond particles in high vacuum with internal spin qubits have been proposed for exploring quantum mechanics. We fabricate an integrated surface ion trap with multiple stabilization electrodes. This facilitates on-chip levitation and, for the first time, optically detected magnetic resonance measurements of a nanodiamond levitated in high vacuum.

Measurable fractional spin for quantum Hall quasiparticles on the disk [0.0]
We study the spin of the localised quasiparticles of lowest-Landau-level quantum Hall states defined on a disk. Since it is related to the quadrupole moment of the quasiparticle charge distribution, it can be measured in an experiment.

Dynamics of Spin Helices in the One-Dimensional $XX$ Model [0.0]
We analytically study the dynamics of spin helices in the one-dimensional $XX$ model. We find a separation of timescales between the in-plane and out-of-plane spin dynamics. One of our key findings is that the spin correlation functions decay as $t-1/2$ at long time, in contrast to the experimentally observed exponential decay.

Dispersive readout of molecular spin qudits [68.8204255655161]
We study the physics of a magnetic molecule described by a "giant" spin with multiple $d > 2$ spin states. We derive an expression for the output modes in the dispersive regime of operation. We find that the measurement of the cavity transmission allows to uniquely determine the spin state of the qudits.

Quantum control of nuclear spin qubits in a rapidly rotating diamond [62.997667081978825]
Nuclear spins in certain solids couple weakly to their environment, making them attractive candidates for quantum information processing and inertial sensing. We demonstrate optical nuclear spin polarization and rapid quantum control of nuclear spins in a diamond physically rotating at $1,$kHz, faster than the nuclear spin coherence time. Our work liberates a previously inaccessible degree of freedom of the NV nuclear spin, unlocking new approaches to quantum control and rotation sensing.

Visualizing spinon Fermi surfaces with time-dependent spectroscopy [62.997667081978825]
We propose applying time-dependent photo-emission spectroscopy, an established tool in solid state systems, in cold atom quantum simulators. 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.

Anisotropic electron-nuclear interactions in a rotating quantum spin 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.
