A No-Cloning Trade-off Between Black Hole No-Hair and Horizon Smoothness

Sudhanva Joshi, Sunil Kumar Mishra ยท 2026

The black hole no-hair theorem is traditionally derived from the uniqueness theorems of general relativity. We show that a quantitative form follows from unitarity together with the standard semiclassโ€ฆ

A Cosmological Uncertainty Relation and Late-Universe Acceleration

Savvas M. Koushiappas ยท 2026

We propose that the size of the universe and its rate of expansion cannot be simultaneously specified with arbitrary precision, a quantum mechanical statement encoded in a deformed commutation relatioโ€ฆ

The quantum group structure of long-range integrable deformations

Koen Schouten, Marius de Leeuw ยท 2026

Quantum integrable spin chains are known to possess a large family of long-range deformations generated by the local, boost and bilocal operators. Although these deformations are well-understood on thโ€ฆ

The A Supergiant Eclipsing Binary BM Cas: An Evolved, Intermediate Mass System

T. J. Davidge ยท 2026

The evolutionary state of the 198 day eclipsing binary BM Cas is examined using spectra that cover five orbital cycles. Radial velocities measured from SiII 6347 and SiII 6371 track the motion of the โ€ฆ

Scalene Yang-Baxter maps and Lax triples

S. Konstantinou-Rizos, T. Kouloukas ยท 2026

We study a generalisation of the set-theoretic Yang-Baxter equation and investigate the connection between its solutions and matrix refactorisation problems. We refer to such solutions as scalene Yangโ€ฆ

On matrix Lax representations for (1+1)-dimensional evolutionary differential-difference equations

Sergei Igonin ยท 2026

Differential-difference matrix Lax representations (Lax pairs), gauge transformations, and discrete Miura-type transformations (MTs) belong to the main tools in the theory of (nonlinear) integrable diโ€ฆ

Nanohertz gravitational waves from the baryon-dark matter coincidence

Alessia Musumeci, Jacopo Nava, Silvia Pascoli, Filippo Sala ยท 2026

The nanohertz gravitational waves (GW) observed by pulsar timing arrays may originate from a cosmological first-order phase transition (PT) at $\sim$ 100 MeV. Taking this possibility seriously motivatโ€ฆ

Integrable Deformations of the Breitenlohner-Maison Model from 4d Chern-Simons Theory

Meer Ashwinkumar, Matthias Blau ยท 2026

We derive integrable deformations of the 2d Breitenlohner-Maison (BM) sigma model that describes the stationary, axisymmetric sector of 4d general relativity, as well as higher-rank generalisations thโ€ฆ

Quarter-indices for basic ortho-symplectic corners

Yasuyuki Hatsuda, Tadashi Okazaki ยท 2026

We study supersymmetric quarter-indices for corner configurations in 4d $\mathcal{N}=4$ super Yang-Mills theory with orthogonal and symplectic gauge groups. For the basic Y-junctions, we obtain exact โ€ฆ

Distortion of a relativistic jet echoing a magnetic flux eruption

Krzysztof Nalewajko, Mateusz Kapusta, Bart Ripperda, Alexander A. Philippov ยท 2026

Magnetized accretion onto spinning black holes can accumulate a large magnetic flux across the event horizon and launch a pair of relativistic jets via the Blandford-Znajek mechanism. In the magneticaโ€ฆ
