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

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

Quantum Probe to the Higher Dimensional Yang-Mills Singularity

M. Mangut, O. Gurtug, M. Halilsoy ยท 2026

We investigate the quantum nature of naked curvature singularities in Einstein-Yang-Mills (EYM) theory using the Horowitz-Marolf (HM) criterion, which assesses quantum singularities via the evolution โ€ฆ

Intergalactic Magnetic Field constraints from detected very high-energy Gamma-Ray Bursts using the Cherenkov Telescope Array Observatory

Teneman Keita, Renaud Belmont, Thierry Stolarczyk ยท 2026

Defined as the magnetic field permeating cosmic voids, the Intergalactic Magnetic Field (IGMF) is thought to be a relic of the Big Bang, tracing a primordial magnetic seed at the origin of all astrophโ€ฆ

Coherent Rollout Oracles for Finite-Horizon Sequential Decision Problems

Nishant Shukla ยท 2026

Coherent quantum rollout for sequential decision problems requires a unitary simulator: randomness must live in explicit quantum registers, and basis-state selectors must be mapped to actions reversibโ€ฆ

Cartan Fluxes in $SU(3)$ Lattice Gauge Theory

Tereza Mendes, Luis E. Oxman, Gustavo M. Simoes, Rafael C.S. Tonhon ยท 2026

We propose and analyze a new method of detecting center vortices and monopoles in lattice Yang-Mills theory. This procedure is sensitive to the intrinsic degeneracy of the center charges, which play aโ€ฆ
