Below are the latest papers in Atom-Ph, offering fresh insights into the structure and behavior of the atomic scale.
This paper provides a comprehensive and up-to-date reference of physical and optical properties for neutral fermionic Yb, consolidating experimental results and theoretical estimates to support applications in quantum optics, precision metrology, and quantum computing.
This paper presents a compact, low-SWaP magneto-optical trap for 87Rb atoms that integrates a monolithic dual-functional metasurface and a planar coil chip to replace bulky optical and magnetic components, achieving nearly an order-of-magnitude performance improvement while drastically reducing size, weight, and power consumption.
This paper derives analytical expressions for the shift in the Bose-Einstein condensation critical temperature of a bosonic species caused by interactions with a second atomic species, distinguishing between cases where the second species is above or below its own critical temperature and applying these results to a Na-K mixture.
This paper presents a new technique for sympathetically cooling arbitrary charged particles in Penning traps using self-cooled electrons from a distant trap that decay to their motional ground state via cyclotron radiation, enabling ultra-low temperature tests of fundamental physics with initial results from the ELCOTRAP experiment at the Max Planck Institute for Nuclear Physics.
This paper proposes a hybrid quantum platform combining polar molecules and neutral atoms to overcome limitations in state detection and interaction speed, utilizing a fast atom-molecule gate based on resonant dipole-dipole exchange to enable high-fidelity quantum logic control, rapid entanglement generation, and diverse applications such as molecular GHZ state preparation and topological qudit states.
This paper demonstrates the first 3D-printed glass atomic vapour cell using vat polymerisation, showcasing its ability to achieve ultra-high vacuum and support advanced quantum applications like laser frequency stabilisation through integrated multi-material architectures and surface functionalisation.
This paper establishes a general framework for quantizing light-matter theories with time-dependent constraints, demonstrating that the irrotational gauge is uniquely suited for such scenarios while showing that the Coulomb gauge is not generally irrotational and thus lacks a special status in time-dependent interactions.
This paper demonstrates a portable two-photon rubidium optical frequency standard utilizing a narrow-linewidth photonic integrated circuit Brillouin laser to achieve a record short-term fractional frequency stability of at one second by overcoming previous shot-noise and intermodulation limitations.
This study experimentally investigates Rydberg-mediated photon-photon interactions in cold-atom EIT systems, revealing distinct nonlinear spectral behaviors in three- and four-level configurations that are explained by conditional superatom and dephasing models respectively, thereby advancing the understanding of many-body physics and the development of unbiased microwave sensors.
This paper demonstrates a method to generate and control a synthetic gauge phase in room-temperature rubidium vapor using Rydberg electromagnetically induced transparency, where the relative polarization angle of laser fields modulates EIT transmission and Rydberg interactions without the need for laser cooling or dipole traps.
