Author(s): Naman Jain, Jin Zhang, Marcus Culemann, and Philipp M. Preiss We demonstrate deterministic preparation of arbitrary two-component product states of fermionic $^{6}\mathrm{Li}$ atoms in an $8×8$ optical tweezer array, achieving motional ground-state fidelities above 98.5%. Leveraging the large differential magnetic moments for spin-resolution, with parallelized… [Phys. Rev. Lett. 136, 223402] Published Fri Jun 05, 2026

Author(s): Myrann Baker-Rasooli, Tangui Aladjidi, Tiago D. Ferreira, Alberto Bramati, Mathias Albert, Pierre-Élie Larré, and Quentin Glorieux A superfluid flows without friction below a critical velocity, exhibiting zero drag force on impurities. Above this threshold, superfluidity breaks down, and the internal energy is redistributed into incoherent excitations such as vortices. We demonstrate that a mobile, finite-mass impurity immersed… ...

Exquisitely tailoring the optical fields of diverse physical quantities has expanded the family of skyrmions, yet such skyrmions...

Softley, Katrin Dulitz, and Roland Wester Photodetachment spectroscopy of ${\mathrm{C}}_{2}^{−}$ anions across the thresholds to the two lowest electronic states of neutral ${\mathrm{C}}_{2}$ was carried out using rotationally cold trapped ions. The electron detachment was observed to follow $p$- and $s$-wave threshold behavior for transiti… [Phys....

Here, we introduce and experimentally validate an analog circuit emulator of Mie scattering by temporally dispersive spheres. The emulator reconstructs the full scattering respons… [Phys. Rev.

Author(s): Wu Wen, Jing Li, and Yunquan Liu We study tunable, nanoscale, femtosecond coherent radiation based on a coupled nanowire pair structure, which is transversely excited by a strong, linearly polarized laser pulse. The structure can function as a nanoscale undulator: the electrons moving through the nanogap are driven by a spatially p… [Phys. Rev. Lett. 136, 223801] Published Mon Jun 01, 2026

Author(s): Wanchen Tao, Ruisi Zhang, Qihe Guo, Lixin He, Tao-Yuan Du, Xingdong Guan, Pengfei Lan, and Peixiang Lu High-harmonic generation (HHG) from liquids offers a potential pathway to attosecond spectroscopy in chemically complex and disordered environments, yet fundamental questions remain open: whether liquid harmonic emission preserves well-defined attosecond synchronization, and whether harmonic emissio… [Phys.
