A self-consistent framework with generalized local order parameters is derived for the Kuramoto model with dyadic and triadic interactions on hypergraphs, showing bistability onset depends on eigenvector correlations between dyadic and triadic structures.
A novel identity connects reduced-model drift and diffusion to the conditional score of the finite-time transition density, turning calibration into a least-squares problem over stationary lagged pairs that preserves invariant statistics and dynamical correlations.
A geometric indicator from the normal width of the stochastic separatrix in a random two-state ecosystem model scales linearly with noise intensity and yields an affine relation to the logarithm of mean transition time.
Fast driving across first-order transitions in relativistic scalar fields produces temperature- and dimension-independent finite-time scaling matching mean-field theory, crossing over to Kibble-Zurek scaling near criticality and nucleation-dominated dynamics at low temperatures.
A duplex voter model on multiplex networks exhibits spontaneous symmetry-breaking and a cusp bifurcation with noise that unfolds explosive versus non-explosive transitions.
Coupled-channel calculations in K- Ξ0, K̄0 Ξ-, K*- Ξ0 and K̄*0 Ξ- channels generate an isoscalar 1/2- resonance at 2109 MeV strongly correlated with the K̄* Ξ system.
A higher-order network comparison of real Ile-de-France mobility traces against a synthetic simulator finds the simulator promising yet limited on path-level statistics.
Void x CMB lensing from Roman mocks is robust to catalog construction choices and forecasts S/N of 13-31 sigma with Planck, SO, and CMB-S4-like data for 2D and 3D voids.
A perturbative analytical model of gravitational waves on an exact Bianchi IV background is derived via the proper-time method and shown to be stable.
The authors introduce analog matching to generate Roman Space Telescope mock catalogs that reproduce emission-line galaxy statistics and highlight the need to match void properties separately from two-point clustering for CMB cross-correlation studies.
The thesis solves coupled Boltzmann equations for freeze-in production and cannibal interactions in scalar theories with Z2/Z3 symmetries, mediator-coupled dark matter, cannibal production during reheating, and a hidden U(1) sector that can undergo an inverse first-order phase transition.
Hybrid neutron star EOS constructed from DDME2 hadronic and two-flavor NJL quark models with quintic interpolation requires early crossover near saturation density to satisfy PSR J0740+6620 mass and NICER radius constraints.
Graph neural network tagging of semi-visible jets from Higgs portal dark sectors at FCC-ee can constrain exotic Higgs branching ratios to dark quarks at the per-mille level across varied invisible fractions.
MeerKLASS reports successful single-dish HI intensity mapping detections that validate the technique for SKAO cosmology surveys.
Momentum-dependent nuclear mean field with K0=230 MeV provides a good description of proton and kaon production and collective flows in 3 GeV Au+Au collisions, outperforming momentum-independent fields.
A review of thermal modifications to light and heavy hadron properties via imaginary-time formalism, effective field theories, unitarized approaches, and lattice QCD, with links to heavy-ion phenomenology.
Quantum confinement in 2D hexagonal crystals like graphene and TMDs produces discrete electronic and excitonic spectra with strongly amplified interactions that enable correlated quantum states.
