Nuclear ground state masses and deformations [PDF]
, 1993 We tabulate the atomic mass excesses and nuclear ground-state deformations of 8979 nuclei ranging from 16O to A = 339. The calculations are based on the finite-range droplet macroscopic model and the folded-Yukawa single-particle microscopic model ...

Simultaneous ground-state cooling of two mechanical modes of a levitated nanoparticle [PDF]
Nature Physics, 2022 A levitated nanoparticle in an optical cavity has been cooled to its motional ground state in two degrees of freedom at the same time. Control of the cavity properties also enabled the observation of the transition from 1D to 2D ground-state cooling. The

Identifying the ground state structures of point defects in solids [PDF]
npj Computational Materials, 2022 Point defects are a universal feature of crystals. Their identification is addressed by combining experimental measurements with theoretical models. The standard modelling approach is, however, prone to missing the ground state atomic configurations ...

Approaching the motional ground state of a 10-kg object [PDF]
Science, 2021 Really cool mirrors Cooling objects to low temperature can increase the sensitivity of sensors and the operational performance of most devices. Removing most of the thermal vibrations—or phonons—such that the object reaches its motional quantum ground ...

The ferroelectric photo ground state of SrTiO3: Cavity materials engineering [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2021 Significance Controlling collective phenomena in quantum materials is a promising route toward engineering material properties on demand. Strong THz lasers have been successful at inducing ferroelectricity in SrTiO3.

Assembly of a Rovibrational Ground State Molecule in an Optical Tweezer. [PDF]
Physical Review Letters, 2021 We demonstrate the coherent creation of a single NaCs molecule in its rotational, vibrational, and electronic (rovibronic) ground state in an optical tweezer. Starting with a weakly bound Feshbach molecule, we locate a two-photon transition via the |c^{3}

Near-optimal ground state preparation [PDF]
Quantum, 2020 Preparing the ground state of a given Hamiltonian and estimating its ground energy are important but computationally hard tasks. However, given some additional information, these problems can be solved efficiently on a quantum computer. We assume that an
