This paper proposes a direct search for QCD axion dark matter using superconducting transmon qubits as quantum sensors, demonstrating that combining cavity resonance with entangled quantum circuits can enhance the detection signal to reach the parameter regions predicted by QCD axion models.
This paper demonstrates that, contrary to the limitations observed in DC magnetometry, entangled GHZ states can enhance the sensitivity of AC magnetometry under parallel Markovian decoherence by scaling the interaction time as to mitigate noise effects and improve the detectable frequency bandwidth.
By extending the IdylliQ model of Quarkyonic matter to include strangeness, this study demonstrates that -quark saturation delays the onset of hyperons to higher densities (--) and suppresses their occupation, thereby mitigating the hyperon puzzle and preserving the stiffness of neutron star equations of state.
Using the topological-diagram approach within the framework, this paper investigates two-body decays into light scalar mesons and demonstrates that interpreting these mesons as tetraquark states provides a consistent explanation for experimental data, including the unexpectedly large branching fraction of , while predicting new decay rates that are accessible to current and future experiments.
This paper investigates how a symmetry-breaking term in composite hybrid inflation triggers a tachyonic instability that generates primordial black holes and a stochastic gravitational wave background, with their specific mass and frequency scales determined by the anomalous dimensions of pion operators and potentially detectable by future observatories.
This paper proposes a universal quantum measurement protocol that extracts the velocity and direction of light dark matter wind from the phase differences between quantum sensors, offering superior sensitivity compared to classical correlation methods without compromising detector performance.
This paper demonstrates that the ionization of dense molecular clouds provides a powerful and competitive method for constraining sub-keV dark matter models that produce UV or X-ray photons through annihilation or decay, with potential for significant improvements through refined observational samples and modeling.
This paper delineates the maximal parameter space for sterile neutrino dark matter by demonstrating that large, flavor-specific lepton asymmetries (with vanishing total asymmetry) can significantly enhance production rates and extend viable mixing angles by up to two orders of magnitude for masses up to 60 keV, while remaining consistent with cosmological constraints.
Using the functional renormalization group method within the two-flavor quark-meson model, this study demonstrates that fluctuation effects significantly lower the critical isospin chemical potential for meson condensation and reveal a phase structure featuring second-order and first-order transitions separating the -dominated phase from other regions.
This paper presents a suite of cosmological simulations incorporating primordial non-Gaussianities from collider physics to characterize their nonlinear signatures in late-time observables and forecasts competitive constraints on these signals using future Vera C. Rubin Observatory weak-lensing data.
