Analysis

This paper addresses a fundamental challenge in quantum transport: how to formulate thermodynamic uncertainty relations (TURs) for non-Abelian charges, where different charge components cannot be simultaneously measured. The authors derive a novel matrix TUR, providing a lower bound on the precision of currents based on entropy production. This is significant because it extends the applicability of TURs to more complex quantum systems.
Reference

The paper proves a fully nonlinear, saturable lower bound valid for arbitrary current vectors Δq: D_bath ≥ B(Δq,V,V'), where the bound depends only on the transported-charge signal Δq and the pre/post collision covariance matrices V and V'.

Analysis

This paper proposes a novel method for creating quantum gates using the geometric phases of vibrational modes in a three-body system. The use of shape space and the derivation of an SU(2) holonomy group for single-qubit control is a significant contribution. The paper also outlines a method for creating entangling gates and provides a concrete physical implementation using Rydberg trimers. The focus on experimental verification through interferometric protocols adds to the paper's value.
Reference

The paper shows that its restricted holonomy group is SU(2), implying universal single-qubit control by closed loops in shape space.

Analysis

This paper provides a general proof of S-duality in $\mathcal{N}=4$ super-Yang-Mills theory for non-Abelian monopoles. It addresses a significant gap in the understanding of S-duality beyond the maximally broken phase, offering a more complete picture of the theory's behavior. The construction of magnetic gauge transformation operators is a key contribution, allowing for the realization of the $H^s \times (H^{\vee})^s$ symmetry.
Reference

Each BPS monopole state is naturally labeled by a weight of the relevant $W$-boson representation of $(H^{\vee})^{s}$.

Proof of Nonexistence of a Specific Difference Set

Published:Dec 31, 2025 03:36
1 min read
ArXiv

Analysis

This paper solves a 70-year-old open problem in combinatorics by proving the nonexistence of a specific type of difference set. The approach is novel, utilizing category theory and association schemes, which suggests a potentially powerful new framework for tackling similar problems. The use of linear programming with quadratic constraints for the final reduction is also noteworthy.

Analysis

This paper explores the connections between holomorphic conformal field theory (CFT) and dualities in 3D topological quantum field theories (TQFTs), extending the concept of level-rank duality. It proposes that holomorphic CFTs with Kac-Moody subalgebras can define topological interfaces between Chern-Simons gauge theories. Condensing specific anyons on these interfaces leads to dualities between TQFTs. The work focuses on the c=24 holomorphic theories classified by Schellekens, uncovering new dualities, some involving non-abelian anyons and non-invertible symmetries. The findings generalize beyond c=24, including a duality between Spin(n^2)_2 and a twisted dihedral group gauge theory. The paper also identifies a sequence of holomorphic CFTs at c=2(k-1) with Spin(k)_2 fusion category symmetry.
Reference

The paper discovers novel sporadic dualities, some of which involve condensation of anyons with non-abelian statistics, i.e. gauging non-invertible one-form global symmetries.
