Exact projective-steering boundary and sample-size optimization for angularly averaged hyperon-antihyperon states
In hyperon-antihyperon production through electron-positron annihilation, quantum steering provides a stricter test of nonclassical spin correlations than entanglement.Nambu-Goldstone Bosons and Quantum Fisher Information
The quantum Fisher matrix and geometric tensor are powerful tools for quantifying the nature of quantum systems.Annihilation feedback on elastic scattering in self-interacting dark matter
Sizable dark-matter self-interactions, motivated by observations of galactic structure, often arise from the exchange of light force mediators.Self-interacting dark matter from radiative bound-state-formation feedback
Observations of galactic structure motivate sizable dark-matter self-interactions at low velocities, naturally realized through light force mediators.This is SParTA: A modular, efficient and scalable transformer architecture for jet-tagging
We present the Sparse Particle-interaction Transformer Architecture (SParTA), a modular, scalable, and efficient transformer for jet tagging at high-energy colliders.Searching for Dense Perturbers in Cold Dark Matter Simulations
Recently, several low-mass, dense perturbers have been inferred from astrophysical observations of gravitational lensing, stellar streams, and satellite galaxies.Non-Classicality in $tW$ system via negativity and geometric quantum discord
We perform a phenomenological study of non-classical correlations in the mixed-dimensional qubit-qutrit system realized by leading order $pp\to tW$ production at $\sqrt{s}=13$ TeV in the leptonic…Real-time quantum simulation of hadron production in deep inelastic scattering
We develop a quantum simulation framework for meson production in deep inelastic scattering based on light-front QCD Hamiltonian formalism.Impact of Irrep Truncations on Quantum Simulations of QCD
Quantum simulations of lattice gauge theories with continuous gauge groups require a choice of basis (how states of the gauge theory map to the qubit computational basis) and truncation scheme…Electric Flux as a Criterion for String Breaking and Schwinger Pair Production
We define string breaking by the midpoint electric field falling to half a flux unit.Testing the inelastic dark matter interpretation of the LZ event with heavy-element experiments
We consider the inelastic dark matter interpretation of the recent 248 keV event observed by LZ and identify different experiments that could test it.Minkowski Functionals of CII Line Intensity Maps: Probing Astrophysics and Primordial Features
Line intensity mapping aims to measure the total cumulative light of spectral lines from galaxies, without resolving individual sources.One generation of the Standard Model as a quantum error-correcting code
Together with a right-handed neutrino, the fermions of one generation of the Standard Model are labelled by five bits, a combinatorial structure tied to anomaly cancellation.Jianmu-Q: Bridging Quantum Field Theory and Quantum Hardware with AI Agents
Quantum computing offers a promising approach to non-perturbative simulations of quantum field theories, particularly for real-time dynamics and systems affected by the sign problem.Entropy Production and Thermalization in Heavy-Quark Langevin Dynamics
Heavy quarks are often treated as Brownian probes of the quark-gluon plasma.Minimal-length kinematics of coherent light and a proposed two-color vacuum chronoscopy
The unification of quantum theory and general relativity suggests the existence of a minimal measurable length, leading to a generalized uncertainty principle (GUP) and an energy-dependent vacuum…Quantum-enhanced Search for Galactic Dark Photons Using Cat-State Cavities
We present a quantum-enhanced search for the Galactic dark-photon background (GDPB), a relativistic and anisotropic vector field that can be produced by dark-matter decay or annihilation in the…Can bosenovae deplete the galactic dark matter?
No: neither through the bosenovae of gravitational atoms formed around stars and compact objects, nor through those of boson stars formed in the galactic dark-matter halo.Efficient numerical evolution of self-gravitating systems with dark-matter-baryon scattering
We present a fast algorithm to numerically evolve a spherically symmetric system consisting of dark matter and gas, including dark-matter-baryon scattering.Ergodic topology sampling toward the continuum with Stochastic Normalizing Flows
In this work we provide numerical evidence that topological freezing in $\mathrm{SU}(3)$ Yang-Mills theory can be mitigated with a flow-based approach, as tested at lattice spacings as fine as…
