Inflationary Fossils Beyond Perturbation Theory

Graded Unitarity in the SCFT/VOA Correspondence

This paper introduces the concept of "graded unitarity" to characterize the non-conventional unitarity of vertex algebras derived from four-dimensional $\mathcal{N}=2$ superconformal field theories and demonstrates that, for Virasoro and affine Kac–Moody algebras, this property uniquely selects the specific central charges and levels known to arise from such four-dimensional theories.

Black holes of multiple horizons without mass inflation

This paper constructs black hole solutions with multiple horizons that avoid mass inflation by utilizing a nonlinear Maxwell field to make coincident inner horizons have vanishing surface gravity, thereby eliminating the exponential growth of perturbations.

Krylov Complexity for Open Quantum System: Dissipation and Decoherence

This paper investigates Krylov complexity in open quantum systems using the Caldeira-Leggett model, revealing that while the complexity captures dissipative features, it remains insensitive to the onset of decoherence due to the mismatch between the Krylov basis and the conventional basis used to study decoherence.

Conformal gauge theory of vector-spinors and spin-3/2 particles

This paper establishes a unique off-shell conformal gauge theory for vector-spinors that resolves previous claims of classical inconsistency and Velo-Zwanziger instability, revealing a massive spin-3/2 particle coupled to a negative-norm spin-1/2 state while yielding a negative conformal anomaly consistent with the Hofman-Maldacena bound.

Fermionic Casimir densities for a uniformly accelerating mirror in the Fulling-Rindler vacuum

This paper investigates the local characteristics of the Fulling-Rindler vacuum for a massive Dirac field in $(D+1)$-dimensional spacetime with a uniformly accelerating mirror, decomposing the fermion condensate and energy-momentum tensor into boundary-free and boundary-induced contributions to reveal their distinct behaviors near the Rindler horizon and the mirror, as well as their contrasting properties compared to the Minkowski vacuum.

Self-gravitating baryonic tubes supported by $\pi$- and $\omega$-mesons and its flat limit

This paper constructs self-gravitating, singularity-free baryonic tube solitons in an $SU(N)$ Einstein non-linear sigma model coupled to $\omega$-mesons, demonstrating that increasing the number of flavors enhances physical predictions by reducing binding energy despite increasing total energy.

The Penrose Transform and the Kerr-Schild double copy

This paper argues that the Kerr-Schild and twistorial double copy prescriptions are equivalent for a broad class of self-dual vacuum solutions, a claim demonstrated through elementary null Lorentz transformations and illustrated with the self-dual Kerr-Taub-NUT spacetime.

Finite-gap potentials as a semiclassical limit of the thermodynamic Bethe Ansatz

This paper demonstrates that the semiclassical limit of the thermodynamic Bethe Ansatz for the Gross-Neveu model naturally reconstructs the algebro-geometric spectra of finite-gap periodic potentials, revealing that the underlying analytic structure is governed solely by the $D_N$ Dynkin diagram and its large-rank limit.
