“…In Refs. [19,22], the computed resonances are clearly narrower than the ones obtained in the present work, and the fact that the two energies given for the lowest 3/2 − and 5/2 + states are similar to ours, but with the quantum numbers exchanged, is probably just an accidental coincidence. The reason for this difference is difficult to determine.…”

“…The present investigation is triggered by the recent experiments [19] on the mirror nucleus, 11 O, which was preceded by related experiments on 10 N [20,21], and quickly followed up by theoretical papers on these and a few neighboring nuclei [22][23][24]. Several previous publications on 11 O and 10 N are available [25][26][27].…”

We investigate the dripline mirror nuclei 11 Li and 11 O, located on the neutron and proton dripline, respectively. We calculate the lowest four states, 3/2 − , 1/2 + , 3/2 + , and 5/2 + , built on double occupancy in the nuclear s 1/2 and p 1/2 valence single-particle states. We use the hyperspherical adiabatic expansion method to solve the three-body problem for a frozen nuclear core surrounded by two identical nucleons. The four analog states in 11 O are obtained with precisely the same interactions as used for the four states in 11 Li, except for addition of the Coulomb interaction from the charge of the substituted valence protons. Surprisingly, the four energies deviate from each other only by less than a few hundred keV. Any of them could then turn out to be the ground state, due to the uncertainty related to the angular momentum and parity dependence of the three-body potential. Still, our calculations marginally favor the 1/2 + state. The structures of these four states in 11 O deviate substantially from the analog states in the mirror, 11 Li.

Convenient Location of a Near-Threshold Proton-Emitting Resonance in B11

The presence of cluster-like narrow resonances in the vicinity of reaction/decay thresholds is a ubiquitous phenomenon with profound consequences. We argue that the continuum coupling, present in the open quantum system description of the atomic nucleus, can profoundly impact the nature of near-threshold states. In this Letter, we discuss the structure of the recently observed near-threshold resonance in 11 B, whose very existence explains the puzzling beta-delayed proton emission of the neutron-rich 11 Be.

Resonant‐Opto‐Thermomechanical Oscillator (ROTMO): A Low‐Power, Large Displacement, High‐Frequency Optically Driven Microactuator

A light‐driven micromechanical oscillator is presented, which can be operated by a low optical power (in the mW, or even the µW range), can produce large mechanical displacements (>5–100 µm), and can be designed to operate at frequencies from sub‐kHz up to more than 200 kHz. The actuation of the oscillator is achieved by an asymmetrically metal‐coated optical microwire configured into a silica micromechanical oscillator. The metalized optical microwire confines and absorbs the light strongly over a short distance, which results in a controlled optical power conversion into heat, and, consequently, into mechanical actuation through the temperature rise and the difference in thermal expansions of the silica microwire and the asymmetrically applied metal layer. Mechanical displacements are amplified further by the resonance operation of the oscillator, which is driven by a low‐power, harmonic optical excitation signal generated by a current‐modulated laser diode. Proper selection of the micromechanical oscillator's geometrical configuration and materials allows for a high‐frequency operation at large mechanical displacements of the oscillator, while relying on low excitation optical power. The presented concept of a fully optically driven micromechanical oscillator may, thus, present a basis for realization of new classes of actuated micro‐opto‐mechanical Systems and similar photonics microdevices.
