Title: Control of the Radiative Heat Transfer in a Pair of Rotating Nanostructures
Authors: Juan R. Deop-Ruano and Alejandro Manjavacas
Abstract summary: We investigate the simultaneous transfer of energy and angular momentum in a pair of rotating nanostructures. We demonstrate that, due to the rotation of the nanostructures, the radiative heat transfer between them can be increased, decreased, or even reversed with respect to the transfer that occurs in absence of rotation. This work unravels the unintuitive phenomena arising from the simultaneous transfer of energy and angular momentum in pairs of rotating nanostructures.

Abstract: The fluctuations of the electromagnetic field are at the origin of the near-field radiative heat transfer between nanostructures, as well as the Casimir forces and torques that they exert on each other. Here, working within the formalism of fluctuational electrodynamics, we investigate the simultaneous transfer of energy and angular momentum in a pair of rotating nanostructures. We demonstrate that, due to the rotation of the nanostructures, the radiative heat transfer between them can be increased, decreased, or even reversed with respect to the transfer that occurs in absence of rotation, which is solely determined by the difference in the temperature of the nanostructures. This work unravels the unintuitive phenomena arising from the simultaneous transfer of energy and angular momentum in pairs of rotating nanostructures.

Force-Gradient Sensing and Entanglement via Feedback Cooling of Interacting Nanoparticles [0.0]
We show that feedback-cooling of two levitated, interacting nanoparticles enables differential sensing of forces and the observation of stationary entanglement. We predict that force-gradient sensing at the zepto-Newton per micron range is feasible and that entanglement due to the Coulomb interaction between charged particles can be realistically observed in state-of-the-art setups.

Long range magnetic dipole-dipole interaction mediated by a superconductor [0.0]
Quantum computation and simulation requires strong coherent coupling between qubits, which may be spatially separated. Here we theoretically investigate a method for achieving such coupling, based on superconducting nano-structures designed to channel the magnetic flux created by the qubits. We show that such structures could channel the magnetic flux, enhancing the dipole-dipole interaction between spin qubits and changing its scaling with distance, thus potentially paving the way for controllably engineering an interacting spin system.

Magnetoconductance modulations due to interlayer tunneling in radial superlattices [4.4591512870240235]
Radial superlattices are nanostructured materials obtained by rolling-up thin solid films into spiral-like tubular structures. We show the appearance of magnetoconductance modulations in the presence of externally applied axial magnetic fields.

Chemical tuning of spin clock transitions in molecular monomers based on nuclear spin-free Ni(II) [52.259804540075514]
We report the existence of a sizeable quantum tunnelling splitting between the two lowest electronic spin levels of mononuclear Ni complexes. The level anti-crossing, or magnetic clock transition, associated with this gap has been directly monitored by heat capacity experiments. The comparison of these results with those obtained for a Co derivative, for which tunnelling is forbidden by symmetry, shows that the clock transition leads to an effective suppression of intermolecular spin-spin interactions.

Effects of the dynamical magnetization state on spin transfer [68.8204255655161]
We show that the complex interactions between the spin-polarized electrons and the dynamical states of the local spins can be decomposed into separate processes. Our results suggest that exquisite control of spin transfer efficiency and of the resulting dynamical magnetization states may be achievable.

Quantum coherent spin-electric control in a molecular nanomagnet at clock transitions [57.50861918173065]
Electrical control of spins at the nanoscale offers architectural advantages in spintronics. Recent demonstrations of electric-field (E-field) sensitivities in molecular spin materials are tantalising. E-field sensitivities reported so far are rather weak, prompting the question of how to design molecules with stronger spin-electric couplings.

Spin current generation and control in carbon nanotubes by combining rotation and magnetic field [78.72753218464803]
We study the quantum dynamics of ballistic electrons in rotating carbon nanotubes in the presence of a uniform magnetic field. By suitably combining the applied magnetic field intensity and rotation speed, one can tune one of the currents to zero while keeping the other one finite, giving rise to a spin current generator.
