Resurgence of Black Holes in Thermal OPE
The momentum-space thermal OPE generically gives an asymptotic high-energy expansion of thermal two-point functions. We study the resurgent structure of this expansion in holographic CFTs at infinite…

Reflected constraint algebras of open Carroll--Weyl null strings
We study whether open null strings admit the full Carroll--Weyl gauge symmetry consistently with endpoint conditions and nontrivial physical degrees of freedom. For endpoints constrained to timelike…

Recovering the leading quantum correction to Newton Potential beyond the Trace Anomaly
The leading quantum correction to the Newton potential induced by the one-loop vacuum effective action of gravity is of order 1/r3. One-loop corrections are also responsible for the trace anomaly.…

Exact TT-Like flows in Integrable Sigma Models
Recently, a general exact autonomy framework for TT-like deformations of 2D integrable sigma models and 4D nonlinear electrodynamics has been developed. The theories are characterized by the…

Entanglement Bounds on Cardy Growth in Higher Dimensions
We propose bounds relating thermal entropy to entanglement in unitary conformal field theories: f4π2a in four dimensions and f2.99830949…\,F in three dimensions. Here f is the…

On the geometric origin of central charges in gravity
Central extensions of asymptotic symmetry algebras are traditionally determined through an explicit computation of the algebra of conserved charges. We show that, within an ambiguity-free covariant…

Two types of hairy black holes in the (3+1)-dimensional O(3) sigma-model
We construct stationary axially symmetric black holes with scalar hair in the gravitating nonlinear O(3) sigma model with a partly negative symmetry-breaking potential. Our results show that it…

On 2-loop AdS2 superstring partition function in AdS5 × S5 and AdS4× CP3
We revisit the 2-loop computation of the partition function of the GS superstring expanded near the AdS2 surface in AdS5× S5 and AdS4× CP3, dual to 12 BPS…

Scattering amplitudes from geometry of kernel-free functionals on piecewise random null paths with memory
We introduce a simple functional of algebra-valued fields with definite Lorentz properties that is kernel-free yet it encodes the structure of tree-level scattering amplitudes. The fields are…

Another Brick in the Wall: Spectral Form Factor of Normal Modes in Horizonless Geometries
We compute the normal mode spectrum and its spectral form factor for a probe scalar wave in smooth horizonless backgrounds. We first consider the BTZ black hole with a brickwall that hides the…

Momentum-space entanglement and mutual information in Kaluza-Klein reduction
In theories with compact extra dimensions, the four-dimensional effective description is obtained by Kaluza-Klein reduction. The state available to a four-dimensional observer is the reduced density…
