Article Abstract

Rabi oscillation is an elementary laser-driven physical process in atoms and artificial atoms from solid-state systems, while it is rarely demonstrated in molecules. Here, we investigate the bond-length-dependent Rabi oscillations with varying Rabi frequencies in strong-laser-field dissociation of H. The coupling of the bond stretching and Rabi oscillations makes the nuclei gain different kinetic energies while the electron is alternatively absorbing and emitting photons. The resulting proton kinetic energy spectra show rich structures beyond the prediction of the Floquet theorem and the well-accepted resonant one-photon dissociation pathway. Our study shows that the laser-driven Rabi oscillations accompanied by nuclear motions are essential to understanding the bond-breaking mechanism and provide a time-resolved perspective to manipulate rich dynamics of the strong-laser-field dissociation of molecules.

Vibrationally resolved resonant Auger spectroscopy (RAS) on bound-continuum transitions enables highly sensitive probing of ultrafast dissociation in molecular core-excited states, where a distinct fragment band arises from Auger decay in dissociation fragments. Here, we theoretically investigate fragment band formation driven by ultrashort X-ray pulses. Unlike conventional molecular bands, fragment RAS peaks exhibit an insensitivity to strong X-ray Rabi oscillations.

Trapped-ion applications, such as in quantum information processing, precision measurements, optical clocks and mass spectrometry, rely on specialized high-performance ion traps. The last three of these applications typically use traditional machining to customize macroscopic 3D Paul traps, whereas quantum information processing experiments usually rely on photolithographic techniques to miniaturize the traps and meet scalability requirements. Using photolithography, however, it is challenging to fabricate the complex 3D electrode structures required for optimal confinement.

Organic luminescent diradicals have recently attracted more attention for their potential applications in quantum science. Here, we have investigated the spin dynamic properties of two solid-state Müller- and Chichibabin-type Kekulé diradicals featuring different distances between two radical centers. The continuous-wave EPR (cw-EPR) together with echo-detected field-swept spectrum (EDFS) prove the existence of a thermally accessible triplet state at room temperature, promising a potential candidate for quantum manipulation as a high-spin state.

Spins within molecules benefit from the atomistic control of synthetic chemistry for the realization of qubits. One advantage is that the quantum superpositions of the spin states encoding the qubit can be coherently manipulated using electromagnetic radiation. The main challenge is the fragility of these superpositions when qubits are to partake of solid-state devices.

Time-varying media break temporal translation symmetry, enabling advanced wave manipulation. However, this phenomenon remains largely unexplored in magnonic systems due to the challenge of achieving rapid and significant changes in magnon dispersion. Here, we construct a time-varying strong coupling between two magnon modes and observe chirped Rabi-like oscillations near the pulse edges.
