A New Bite Into Dark Matter with the SNSPD-Based QROCODILE Experiment [55.46105000075592]
We present the first results from the Quantum Resolution-d Cryogenic Observatory for Dark matter Incident at Low Energy (QROCODILE) The QROCODILE experiment uses a microwire-based superconducting nanowire single-photon detector (SNSPD) as a target and sensor for dark matter scattering and absorption. We report new world-leading constraints on the interactions of sub-MeV dark matter particles with masses as low as 30 keV.

Cooperative atomic emission from a line of atoms interacting with a resonant plane surface [0.0]
Casimir-Polder effects can modify collective atomic frequency shifts and decay rates. We show that cooperative effects, expected in free space, are absent when the atoms are close to a surface. We propose the study of Cesium 6P3/2 atoms in front of a resonant metasurface as the most promising scenario for experimentally demonstrating the results of our study.

Confinement Induced Resonances in Spherical Shell Traps [0.0]
We have computed exactly the energy spectrum and corresponding wave functions of two bosonic particles confined in a shell-shaped trap. By working close to the found CIRs, these results offer a new way to enhance the atom-atom interaction in the atomic gas.

Dispersive cavity-mediated quantum gate between driven dot-donor nuclear spins [0.0]
We study the interaction of a microwave resonator with a hybrid quantum dot-donor system. We find that driving the QDD system allows to compensate the frequency mismatch between the donor nuclear spin splitting in the MHz regime and typical superconducting resonator frequencies in the GHz regime. While we expect this coupling to be weak, we predict that coupling the nuclear spins of two distant QDD systems dispersively to the microwave resonator allows the implementation of a resonator mediated nuclear spin two-qubit $sqrtimathrmSWAP$ gate.

Controlled coherent dynamics of [VO(TPP)], a prototype molecular nuclear qudit with an electronic ancilla [50.002949299918136]
We show that [VO(TPP)] (vanadyl tetraphenylporphyrinate) is a promising system suitable to implement quantum computation algorithms. It embeds an electronic spin 1/2 coupled through hyperfine interaction to a nuclear spin 7/2, both characterized by remarkable coherence.

Room Temperature Coherent Control of Spin Defects in hexagonal Boron Nitride [0.0]
Optically active defects in solids with accessible spin states are promising candidates for solid state quantum information and sensing applications. We realize coherent control of ensembles of boron vacancy centers in hexagonal boron nitride (hBN) Our results are important for employment of van der Waals materials for quantum technologies.

Optically pumped spin polarization as a probe of many-body thermalization [50.591267188664666]
We study the spin diffusion dynamics of 13C in diamond, which we dynamically polarize at room temperature via optical spin pumping of engineered color centers. We find good thermal contact throughout the nuclear spin bath, virtually independent of the hyperfine coupling strength. Our results open intriguing opportunities to study the onset of thermalization in a system by controlling the internal interactions within the bath.

Effect of phonons on the electron spin resonance absorption spectrum [62.997667081978825]
We model the effect of phonons and temperature on the electron spin resonance (ESR) signal in magnetically active systems. We find that the suppression of ESR signals is due to phonon broadening but not based on the common assumption of orbital quenching.
