This thesis investigates large- melonic quantum field theories, including Sachdev-Ye-Kitaev-like models, by developing the -extremization method to solve their strongly-coupled infrared conformal limits and demonstrating these techniques through the analysis of a quartic Yukawa tensor model.
By employing multiparticle factorization and soft kinematics, this paper demonstrates that the infinite tower of higher-spin string excitations imposes such rigid constraints that the bosonic string's Regge intercept is uniquely fixed and specific deformations of superstring amplitudes are strictly forbidden by unitarity.
This paper proposes a covariant orbital-spin decomposed amplitude using massive canonical-spinor variables to streamline partial wave analysis of complex decay chains, a method validated by consistent results in the TF-PWA framework for the decay.
This paper verifies the hypothesis that counterexamples to the Lattice Weak Gravity Conjecture in heterotic string compactifications necessarily feature fractionally charged confined monopoles, demonstrating that the degree of such violation is bounded by the maximal order of the gauge group's center.
This paper demonstrates that while BPS geodesics with enhanced symmetry remain unchanged in the scattering of multiple Abelian-Higgs vortices, the excitation of massive bound modes introduces forces that significantly deform generic vortex trajectories and enhance chaotic behavior in the final state.
This paper uncovers new nonlinear facets of gravity within the Einstein-Klein-Gordon system, demonstrating higher harmonic generation, spectral broadening, and focusing, while showing that weak frequency sensitivity in vacuum wave scattering at quadratic order helps explain the smooth behavior of black hole mergers yet cautions against overly simplistic waveform interpretations.
This paper reformulates the strong coupling expansion of large- QCD as constrained one-dimensional spin chains, demonstrating that while specific subsectors remain integrable, the full system loses integrability due to zigzag symmetry constraints, yet still successfully estimates the roughening transition point.
This paper demonstrates that the adjoint sector of large- SU() matrix quantum mechanics exhibits universal Regge trajectories at criticality, corresponding to oscillatory excitations of short folded open strings in dual two-dimensional string theory, which transition into long strings extending into the Liouville direction slightly away from criticality.
This paper derives characteristic identities for the split Casimir operator of the Lie algebra in spinor representations to construct invariant projectors, calculate colour factors for ladder Feynman diagrams in gauge theories, and obtain a new -invariant solution to the Yang-Baxter equation.
This paper constructs diverse families of exact solutions in General Relativity coupled to non-linear sigma models—including bumpy black holes, stars, and cosmologies in various dimensions—by utilizing first-order Bogomol'nyi-Prasad-Sommerfield relations for coset scalars.
This paper utilizes the method of resurgent continuation of transseries to establish a novel correspondence between the -series counting quarter-BPS black hole degeneracies and invariants of Chern-Simons theory on specific orientation-reversed 3-manifolds.
This paper employs a distributional formalism to derive generalized junction conditions for arbitrary gravitational theories based on curvature invariants, establishing specific continuity requirements for the Riemann tensor and its derivatives that determine the existence of thin shells, gravitational double layers, or impulsive waves.
This article reviews the fifty-year evolution of supersymmetry and supergravity from 1974 to 2024, highlighting their pivotal role in unifying fundamental interactions, their profound impact on cosmology and string theory, and the ongoing experimental efforts to validate these models.
This paper proposes that probabilistic classical field theories are equivalent to quantum field theories when formulated using fluctuating field observables, which introduce non-commuting operators and a functional integral formalism derived from classical probability laws.
This paper introduces a novel virtual rishon framework that enforces gauge symmetry via intermediate quantum-link representations to enable scalable simulations of lattice gauge theories in d+1 dimensions using both classical tensor networks and near-term quantum hardware, validated by benchmarking on the multi-flavor Schwinger model and 2D string tension.
This paper utilizes the isomorphism between the six-dimensional nilpotence variety and within the pure spinor superfield formalism to classify and explicitly construct various six-dimensional supermultiplets, including vector, hyper, and supergravity multiplets, by associating them with line bundles and higher-rank equivariant vector bundles on projective spaces.
This paper investigates the dynamics of chiral gauge theories with spinor fermions using supersymmetric limits and anomaly-mediated breaking, predicting that the theory is gapped for while exhibiting spontaneous breaking of the global symmetry to for .
This paper establishes a relative Poincaré–Verdier duality for supermanifolds via Berezin fiber integration to rigorously define picture changing operators and prove the equivalence of component, superspace, and geometric formulations of 3d supergravity.
This paper investigates the relationship between non-local magic and entanglement in quantum many-body systems, establishing bounds on classical simulation hardness and conjecturing a linear scaling in conformal field theories, while proving that in holographic duals, non-local magic vanishes precisely when gravitational back-reaction is absent and is approximately equal to the rate of change of minimal surface area with respect to cosmic brane tension.
This paper proposes that the patterns of spontaneous symmetry breaking and vacuum degeneracy in scalar and gauge field systems can be qualitatively classified by modeling the vacuum manifold as a principal groupoid bundle and analyzing the singular foliation it induces on the moduli space of vacuum expectation values.
