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 theoretically extends the Lifshitz formula to demonstrate that the anomalous magnetic moment of Dirac fermions significantly enhances the fermionic Casimir energy under magnetic fields, particularly through the gapless behavior of the lowest Landau level, while providing quantitative estimates for electrons, muons, and constituent quarks.
Using Monte Carlo simulations on SU(3) gauge theory lattices, this study investigates topologically stable strings formed at domain wall junctions in the deconfined phase, revealing that their free energy is dominated by the walls and that thermal fluctuations near the transition point cause these structures to decay into confined-deconfined interfaces.
This contribution applies the string-Carroll expansion scheme to systematically analyze and classify the dynamics of closed bosonic strings in the spacetime background of a non-extremal BTZ black hole near the horizon, thereby revealing new features of their solution space.
This paper identifies a novel noncompact Lie symmetry, generated by on-site U(1) fermion number and non-on-site Majorana translation, that enforces the existence of Fermi surfaces with at least two noncontractible components in quantum lattice fermion models, thereby realizing a powerful form of symmetry-enforced gaplessness.
This paper re-derives gauge-invariant stochastic inflation equations incorporating all metric and scalar degrees of freedom, validates their numerical implementation within the BSSN formulation of Numerical Relativity across slow-roll and ultra slow-roll scenarios, and demonstrates their robustness in simulating fully non-linear stochastic dynamics with retained gradients and anisotropic expansion.
This work calculates the static Love numbers for scalar and Dirac perturbations of acoustic black holes in (3+1) and (2+1) dimensions and shows that while scalar responses exhibit dimension-dependent behavior, including vanishing for certain modes, fermionic responses universally follow simple power laws, thereby highlighting fundamental qualitative differences between integer- and half-integer-spin fields in analog gravity systems.
This review synthesizes recent advancements in black hole thermodynamics by utilizing topological numbers to categorize diverse black hole systems into universality classes, thereby analyzing critical points, phase transitions, and their implications for quantum gravity.
This paper investigates the asymptotic causal structure of gravitational effective field theories in black-hole backgrounds, demonstrating that while genuine asymptotic superluminality can occur in spacetime dimensions greater than four, the four-dimensional case remains causally identical to the Schwarzschild solution regardless of higher-derivative corrections, necessitating alternative definitions of superluminality such as asymptotically AdS backgrounds or finite-distance cut-offs.
This paper analyzes charged particle multiplicity distributions in proton-proton collisions to identify a reciprocal symmetry () in KNO scaling violations observed by ATLAS and CMS, utilizing a derived local constraint at the mean multiplicity to extract entanglement entropy while avoiding uncertainties from the distribution tail.
Using a holographic AdS/QCD model, this paper demonstrates that introducing an energy scale in anti-de Sitter space alters the topological class of black holes, thereby mapping the confined-deconfined phase transition to a change in topological charge that occurs at a finite critical temperature via the Hawking-Page transition.
