Abstract: In the framework of linearized quantum gravity, we study the quantum gravitational interaction between two nonpointlike objects induced by fluctuating gravitomagnetic fields in vacuum. We find that, in addition to the quantum gravitational interaction induced by fluctuating gravitoelectric fields previously studied, there exists a quantum gravitomagnetic interaction. This interaction originates from the interaction between the instantaneous localized mass currents in nonpointlike objects induced by the fluctuating gravitomagnetic fields. Using fourth-order perturbation theory, we derive the explicit form of the quantum gravitomagnetic interaction energy, which shows an $r^{-10}$ dependence in the near regime and an $r^{-11}$ dependence in the far regime, where $r$ is the distance between the two objects. This interaction energy is expected to be significant when the gravitomagnetic polarizability of the objects is large.

Quantum entanglement of masses with non-local gravitational interaction [0.0]
We consider an energy-momentum tensor describing two test particles of equal mass with each possessing some non-zero momentum. We find that the change in the gravitational energy due to the self-interaction terms is finite. We study the quantum gravity induced entanglement of masses for two different scenarios.

Mechanism for the quantum natured gravitons to entangle masses [0.0]
This paper points out the importance of the quantum nature of the gravitational interaction with matter in a linearized theory of quantum gravity induced entanglement of masses (QGEM) We will show how the quantum interaction entangles the steady states of a closed system of two test masses placed in the harmonic traps, and how such a quantum matter-matter interaction emerges from an underlying quantum gravitational field.

Relativistic aspects of orbital and magnetic anisotropies in the chemical bonding and structure of lanthanide molecules [60.17174832243075]
We study the electronic and ro-vibrational states of heavy homonuclear lanthanide Er2 and Tm2 molecules by applying state-of-the-art relativistic methods. We were able to obtain reliable spin-orbit and correlation-induced splittings between the 91 Er2 and 36 Tm2 electronic potentials dissociating to two ground-state atoms.

Quantum interference in external gravitational fields beyond General Relativity [0.0]
We study the phenomenon of quantum interference in the presence of external gravitational fields. In the non-relativistic regime, it is possible to come across a gravitational counterpart of the Bohm-Aharonov effect. On the other hand, beyond the Newtonian approximation, the relativistic nature of gravity plays a crucial role.

We study the effects of cavity mediated long range magnetic interactions and optical lattices in ultracold matter.

Gravitational waves affect vacuum entanglement [68.8204255655161]
The entanglement harvesting protocol is an operational way to probe vacuum entanglement. Using this protocol, it is demonstrated that while the transition probability of an individual atom is unaffected by the presence of a gravitational wave, the entanglement harvested by two atoms depends sensitively on the frequency of the gravitational wave. This suggests that the entanglement signature left by a gravitational wave may be useful in characterizing its properties, and potentially useful in exploring the gravitational-wave memory effect and gravitational-wave induced decoherence.

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.
