  1. 20. Quantum Sensing and Radiative Decay
    Miguel Angel Soto Alcaraz
    16/11/2025, 11:00

    A novel strategy for detecting radiative decay of very weakly interacting particles is explored by leveraging the extreme sensitivity of quantum devices, to faint electromagnetic signals. By modeling the effective electric field induced by the decay photons, the response of quantum sensors is evaluated across two particle physics scenarios: the cosmic neutrino background and two-component dark...

  2. 18. Helicity space entanglement in 2-2 scattering
    Rahul Muraleedharan (University of Oklahoma)

    Recent studies suggest that the symmetries underlying fundamental interactions may have a quantum-information–theoretic origin.By analyzing the relativistic S-matrix as a quantum logic gate acting on the bipartite Hilbert space, one can explicitly trace how Lagrangian-level symmetries are realized in the space of quantum states. In this work, we focus on the entanglement structure in the...

  3. 2. Constraints on Symmetric Dark Matter from Neutron Star Capture and Collapse
    Yuxin Liu (International Centre for Theoretical Physics Asia-Pacific)

    Dark matter (DM) models with a conserved particle$-$antiparticle number, $n_\chi-n_{\tilde \chi}$, and the asymmetry in the cosmological abundance $n_\chi\neq n_{\tilde \chi}$, are known to be challenged by the existence of old neutron stars (NSs), as the sufficient accumulation of DM will lead to the collapse of NSs into black holes. We demonstrate that the applicability of these constraints...

  4. 9. Quantum Entanglement in Yang-Mills
    Kunfeng Lyu

    We study the quantum entanglement in Yang-Mills theory. Due to the Color-Kinematic duality, the color and helicity parts are separable which enables the study of the quantum entanglement in color space and helicity space individually. In color space, we compute the quantum entanglement in the SU(2) and SU(3) gauge group and display the large N limit. The Dimension-six operators preserve this...

  5. 33. Gravitational Waves from Phase Transitions in an Early Matter Dominated Epoch
    Fazlollah Hajkarim (University of Oklahoma)
    16/11/2025, 12:12

    We study how an early matter dominated (EMD) epoch affects the thermal history and first-order phase transitions (FOPT) in the early Universe. A heavy scalar with field-dependent decay width drives reheating, producing non-adiabatic cooling and heating phases. These transitions change the expansion of Universe, shaping the primordial gravitational wave (GW) spectra from FOPT, which can exhibit...

  6. 28. Gravitational Waves and Primordial Black Holes in First-Order Phase Transitions
    Cash Hauptmann (University of Nebraska - Lincoln)
    16/11/2025, 12:30

    Many extensions to the Standard Model are expected to yield first-order phase transitions (FOPTs) which could produce detectable signals of gravitational waves (GWs) and observable abundances of primordial black holes (PBHs). We study such FOPTs within conformal $B-L$ models, which naturally accommodate stronger GW signals due to supercooling. By scanning large regions of parameter space, we...
