Integrability for the spectrum of Jordanian AdS/CFT

This paper demonstrates that the spectrum of the sl(2,R)\mathfrak{sl}(2,R) sector in Jordanian-deformed AdS5×S5AdS_5\times S^5 string theory remains integrable and solvable via the Baxter framework despite the breaking of highest-weight symmetry by a non-abelian Drinfel'd twist, yielding analytic results that match the deformed string spectrum at the one-loop level.

Operator Formalism for Laser-Plasma Wakefield Acceleration

This paper introduces a novel operator-based framework for laser-plasma wakefield acceleration that utilizes specific mathematical operators to systematically describe coupled laser-plasma dynamics, establishes a formal connection to Hilbert-space theory for analyzing energy transfer, and integrates neural operators to enable efficient reduced-order modeling and predictive control.

Analytic approach to boundary integrability with application to mixed-flux AdS3×S3AdS_3 \times S^3

This paper proposes an analytic approach to determine integrable boundary conditions in two-dimensional sigma-models by analyzing the divisor structure of the Lax connection, which is applied to open strings on AdS3×S3AdS_3 \times S^3 with mixed flux to identify two distinct branches of integrable boundaries that generalize known conformal D-branes.

Integrable Free and Interacting Fermions

This paper establishes rigorous integrability conditions for one-dimensional quantum systems to be classified as free or interacting fermions by defining free fermions through the simultaneous satisfaction of the Yang-Baxter equation and Shastry's decorated star-triangle relation, and provides a procedure to construct integrable interacting models, such as the Hubbard and XY models, via deformations of these free fermionic RR-matrices.

Cut and project schemes in the Poincaré disc: From cocompact Fuchsian groups to chaotic Delone sets

This paper establishes a cut and project scheme based on cocompact Fuchsian groups acting on the Poincaré disc, demonstrating that specific fundamental domains generate chaotic Delone sets with countably infinite tile lengths, thereby addressing the potential for improved graded metamaterials and extending previous work on hyperbolic aperiodic structures.

Scattering for Defocusing NLS with Inhomogeneous Nonlinear Damping and Nonlinear Trapping Potential

This paper establishes the global existence, uniform H1H^1 boundedness, and scattering of solutions for an energy-subcritical defocusing nonlinear Schrödinger equation in R3\mathbb{R}^3 with inhomogeneous nonlinear damping and trapping potential by introducing a novel virial-modified energy to overcome the loss of energy monotonicity caused by spatially dependent damping.

What is a minimum work transition in stochastic thermodynamics?

This paper demonstrates that formulating a well-posed minimum work transition problem in finite-time stochastic thermodynamics requires imposing speed limits on control protocols, a constraint that distinguishes optimal equilibration from minimum work processes and reveals that only generalized Schrödinger bridges remain physically consistent when such limits are removed.
