This paper utilizes topological arguments to prove that heterotic horizons preserving six supersymmetries must have spatial sections diffeomorphic to , while simultaneously demonstrating the non-existence of such heterotic AdS solutions under compactness assumptions, and further re-examines the conditions for four-supersymmetry backgrounds in light of recent Calabi-Yau manifold classifications.
This paper derives the non-local non-stabiliserness (magic) in gluon and graviton scattering, demonstrating that the helicity basis naturally manifests this quantum resource for standard interactions but fails to do so when new physics operators are introduced.
This paper proposes that inflationary gravitational particle production generates significant late-time dark matter fluctuations, thereby expanding the viable parameter space for four distinct dark matter scenarios (Inert, WIMPy, UFOy, and FIMPy) while remaining consistent with current cosmological constraints.
This paper investigates non-minimally coupled scalar field inflation within Loop Quantum Cosmology with inverse-volume corrections, demonstrating that the model's predictions for inflationary observables align with current observational data while the non-minimal coupling significantly enhances the probability of achieving sufficient inflation by enlarging the favorable phase-space volume.
This paper establishes the existence of nonlinear wave operators and proves small-data asymptotic completeness for the Maxwell-Higgs system with scalar potential on subextremal Kerr spacetimes by constructing a gauge-invariant scattering map that relies on a transfer principle from linear estimates, provided the absence of superradiant instability.
This paper utilizes modern amplitude methods and a heavy-mass effective field theory to compute and resum the third post-Minkowskian gravitational scattering dynamics of spinning black holes, demonstrating that the resulting eikonal phase correctly reproduces the characteristic ring singularity of the Kerr metric.
This paper demonstrates that single-minus tree-level -graviton scattering amplitudes are nonvanishing for specific kinematic configurations, deriving a Berends-Giele recursion relation that simplifies to a product of soft factors in a restricted decay region and reveals a connection to a recursive Ward identity.
This paper investigates the Casimir effect for a massive scalar field in a five-dimensional Lorentz-violating aether compactification, deriving closed-form expressions that reveal how the quasiperiodic parameter controls the transition between attractive and repulsive forces, while the Lorentz-violating parameter amplifies vacuum interactions and the compactification ratio stabilizes the system, particularly in high-compactification regimes.
This paper proposes that Hermiticity in quantum mechanics is a symmetry arising from global inner product conservation, which becomes obstructed by causal horizons in black hole geometries, thereby inducing effective non-Hermitian dynamics that unify gravity, entropy production, and the generalized second law of thermodynamics.
Using high-resolution Lyman- forest data and new Sherwood-Relics simulations, this study presents updated constraints on the isocurvature fraction of post-inflationary axion-like particles, revealing a tentative detection of a non-zero contribution while establishing competitive upper bounds that surpass previous large-scale structure limits.
This dissertation employs self-consistent holographic Einstein-Maxwell-dilaton and Einstein-Born-Infeld-dilaton models to investigate the mass spectra and melting dynamics of heavy and exotic mesons under finite temperature, baryon density, and external magnetic fields, revealing sequential dissociation patterns and anisotropic magnetic catalysis effects.
Using the miniDSE scheme of Dyson-Schwinger equations, this study demonstrates that including dynamical charm quark fluctuations in QCD induces a moderate but noticeable shift of approximately 2–3% to lower chemical potential in the location of the critical endpoint, highlighting the significance of heavy-flavor dynamics in precision studies of the QCD phase structure.
This paper demonstrates that a lunar laser interferometer can directly probe the kinetic sector of the effective field theory of dark energy by measuring horizon-scale metric fluctuations, thereby enabling constraints on the dark energy sound speed and kinetic operators that are inaccessible to traditional background expansion probes.
This paper analytically confirms the N^(3/2) scaling of the free energy for a family of 3d N = 2 chiral quiver gauge theories constructed via un-higgsing by utilizing exact integral identities from Giveon-Kutasov duality to map them to non-chiral quivers with chiral flavors where the scaling is already established.
Employing the STOchastic LAttice Simulation (STOLAS) code, this study investigates the spatial profiles and topological structures of curvature perturbations in multi-waterfall hybrid inflation models, validating the stochastic-N algorithm while revealing how stochastic noise drives defect reconnection and imposes upper bounds on perturbations in cubic potential scenarios.
The authors construct and classify asymptotically flat dyonic hairy black hole solutions in U(1) gauge-invariant scalar-vector-tensor theories with cubic and quartic interactions, demonstrating that magnetic charge activates specific interaction sectors to generate new solution branches and requires consistency conditions to ensure the field equations remain second-order.
This study investigates the magnetic moments of strange hidden-bottom pentaquark states within the constituent quark model across molecular and compact configurations, finding that their electromagnetic properties are primarily governed by global spin–flavor correlations and light–strange quark dynamics rather than specific internal clustering details due to heavy-quark mass suppression.
This paper employs linear and non-linear dimensionality reduction techniques, including physics-informed autoencoders, and topological data analysis to compress the high-dimensional parameter space of Type IIB flux vacua, revealing non-trivial correlations and organizing them by phenomenological features as a necessary step towards foundation models in string phenomenology.
This paper analyzes the exact marginality of orbifold resolution deformations using closed superstring field theory, demonstrating that the deformation is unobstructed up to third order and reproduces the Eguchi-Hanson gravitational instanton metric in the field theory limit.
This thesis establishes a rigorous, algorithmic framework for restoring gauge and BRST invariance in chiral gauge theories using the BMHV scheme with non-anticommuting , successfully demonstrating its feasibility through the complete 4-loop renormalisation of an Abelian theory and the 1-loop renormalisation of the full Standard Model.
