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 demonstrates that the trace-free Einstein tensor cannot be derived from any local action functional via variation with respect to the metric, even when the requirement of diffeomorphism invariance is removed.
This paper investigates Krylov complexity in Schrödinger field theory with positive chemical potential, revealing that the resulting single-sided, truncated Wightman spectrum induces a dynamical transition in Lanczos coefficients that drives a crossover from early-time hyperbolic growth to late-time quadratic complexity growth.
This paper computes the hadronic vacuum polarization to three loops in two-flavor chiral perturbation theory, identifying six elliptic master integrals and establishing previously unknown relations essential for renormalizability to provide a foundation for phenomenological and lattice QCD applications.
This paper proposes that semiclassical baby universes in AdS/CFT function as logical qubits encoded via pseudorandom dynamics, which resolves paradoxes of state cloning and singularity fate by ensuring that their microstates remain inaccessible to any single boundary observer through emergent complementarity.
This paper resolves the ambiguity of field space geometry in gravitational effective field theories by developing a frame-covariant framework that interprets conformal frames as distinct foliations of a higher-dimensional auxiliary geometry, thereby demonstrating that key Swampland Distance Conjectures are universal consequences of frame covariance rather than specific quantum gravity constraints.
This paper investigates the vacuum expectation values of the field squared and energy-momentum tensor for a charged scalar field on a (2+1)-dimensional Beltrami pseudosphere with a compactified azimuthal coordinate, revealing that while geometric contributions are divergent, topological effects are finite and exhibit distinct power-law behaviors depending on the field mass, curvature coupling, and compactification scale.
This paper investigates how a time-dependent Newton constant and non-conserved energy-momentum tensor, constrained by the Bianchi identity and thermodynamic principles, lead to specific power-law relations between and black hole mass that determine the black hole's evaporation behavior and temperature evolution based on the chosen entropy definition.
This paper presents a new family of multi-centered extremal rotating black hole solutions in five-dimensional vacuum Einstein gravity, constructed by promoting harmonic functions of the Myers-Perry solution to multiple sources, which yield smooth, singularity-free spacetimes with bubble-supported binary configurations and no closed timelike curves.
This paper demonstrates that while the lowest-order Blandford-Znajek jet power is universal across generic stationary and axisymmetric black-hole spacetimes, the next-leading-order corrections depend on the specific spacetime geometry, offering a potential method to distinguish rapidly rotating black holes through combined measurements of jet luminosity and angular velocity.
This paper proposes a continuum QED description with emergent symmetries for the multicritical point in a staggered Fradkin-Shenker model, demonstrating how it connects to the original model and establishing a duality with the easy-plane model that implies a deconfined quantum multicritical point separating a gapped spin liquid from a Néel phase.
