Hep-Th, or high-energy theoretical physics, explores the fundamental building blocks of our universe and the forces that govern them. Researchers in this field use complex mathematics to understand everything from subatomic particles to the behavior of black holes, often pushing the boundaries of what we know about space and time.
At Gist.Science, we monitor the arXiv repository to ensure you stay ahead of the curve in this rapidly evolving discipline. For every new preprint uploaded to arXiv under this category, our team generates both accessible plain-language overviews and detailed technical summaries, making cutting-edge research understandable regardless of your background.
Below are the latest papers in high-energy theoretical physics, curated to help you navigate the most significant recent discoveries.
This paper elucidates the physical distinction between ghosts and unstable particles in quantum field theory by analyzing their differing asymptotic behaviors and analytic structures, demonstrating that ghosts do not decay but are masked by multi-particle interference, thereby confirming the absence of freely propagating ghost particles in the asymptotic limit.
This paper demonstrates that universal properties of 2+1d topological phases, including those beyond standard and matrices, can be extracted from ground-state bulk entanglement on locally-achiral manifolds, while also establishing a connection between the vanishing Pontryagin number in four dimensions and the existence of nontrivial time-reversal symmetry-protected topological order detectable via a new entanglement measure.
This paper presents the first construction of exact, positive-energy, normalizable Dirac wave packets in an attractive Coulomb-like potential, revealing unique families that exhibit spin-independent probability densities, a freezing of time evolution at critical coupling, and a direct correspondence to free-Schrödinger Hermite-Gauss wave packets in the nonrelativistic limit.
This paper proposes a holographic dual for a two-dimensional PT-symmetric boundary conformal field theory using an imaginary scalar field on an end-of-the-world brane, revealing spontaneous PT symmetry breaking at strong coupling and demonstrating that the resulting quantum quenched state exhibits entanglement entropy growth exceeding standard Cardy state predictions.
This paper constructs the simplest pseudo-Hermitian supersymmetric quantum field theory by formulating a pseudo-Hermitian Wess-Zumino model with symplectic fermions and a spin-half boson, demonstrating that its inability to support non-vanishing cubic interactions can be resolved by coupling it with a Hermitian Wess-Zumino model while preserving supersymmetry.
This paper proposes a dynamical mechanism where a new scalar field induces a transient bias to trigger the decay of CP domain walls formed by spontaneous CP violation, thereby resolving the associated cosmological constraint while simultaneously providing a dark matter candidate through the field's coherent oscillations.
This paper establishes a nonlinear graviton theorem for higher-spin self-dual gravity by demonstrating that small deformations of the complex structure in non-projective twistor space generate an infinite-dimensional manifold of holomorphic planes, which encodes solutions to the theory and reveals its integrability through a Lax pair.
This paper presents a universal, closed-form expression for the dynamical Love numbers of Schwarzschild black holes that holds to all orders for any spin and multipole, revealing a factorized structure rooted in near-zone anomalous dimensions and far-zone Newtonian phase effects, which is independently verified using shell effective field theory up to .
This paper derives the operator product expansion for two operators in a spin-orbit coupled bosonic system, with a specific focus on determining the contact density term that governs the system's universal physics.
This paper extends force-free magnetosphere studies to rotating Kerr black holes by explicitly constructing the electromagnetic field and its backreaction on spacetime via linearized Einstein equations, revealing significant modifications to accretion disk observables and jet-launching mechanisms.
