Analysis

This paper explores eigenfunctions of many-body system Hamiltonians related to twisted Cherednik operators, connecting them to non-symmetric Macdonald polynomials and the Ding-Iohara-Miki (DIM) algebra. It offers a new perspective on integrable systems by focusing on non-symmetric polynomials and provides a formula to construct eigenfunctions from non-symmetric Macdonald polynomials. This work contributes to the understanding of integrable systems and the relationship between different mathematical objects.
Reference

The eigenfunctions admit an expansion with universal coefficients so that the dependence on the twist $a$ is hidden only in these ground state eigenfunctions, and we suggest a general formula that allows one to construct these eigenfunctions from non-symmetric Macdonald polynomials.

ArXiv

Analysis

This paper investigates the structure of twisted Jacquet modules of principal series representations of GL(2n) over a local or finite field. Understanding these modules is crucial for classifying representations and studying their properties, particularly in the context of non-generic representations and Shalika models. The paper's contribution lies in providing a detailed description of the module's structure, conditions for its non-vanishing, and applications to specific representation types. The connection to Prasad's conjecture suggests broader implications for representation theory.

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.

Analysis

This paper addresses the important problem of decoding non-Generalized Reed-Solomon (GRS) codes, specifically Twisted GRS (TGRS) and Roth-Lempel codes. These codes are of interest because they offer alternatives to GRS codes, which have limitations in certain applications like cryptography. The paper's contribution lies in developing efficient decoding algorithms (list and unique decoding) for these codes, achieving near-linear running time, which is a significant improvement over previous quadratic-time algorithms. The paper also extends prior work by handling more complex TGRS codes and provides the first efficient decoder for Roth-Lempel codes. Furthermore, the incorporation of Algebraic Manipulation Detection (AMD) codes enhances the practical utility of the list decoding framework.
Reference

The paper proposes list and unique decoding algorithms for TGRS codes and Roth-Lempel codes based on the Guruswami-Sudan algorithm, achieving near-linear running time.

Geometric Approach to Quantum Mechanics

Published:Dec 30, 2025 00:48

ArXiv

Analysis

This paper offers a geometric perspective on one-dimensional quantum mechanics, using the framework of De Haro's Geometric View of Theories. It clarifies the relationship between position and momentum representations as different trivializations of a Hilbert bundle, and the Fourier transform as a transition function. The analysis extends to the circle, incorporating twisted boundary conditions and connections. This approach provides a novel way to understand quantum mechanical representations and dualities.
Reference

The paper demonstrates how the Geometric View organizes quantum-mechanical representations and dualities in geometric terms.

Analysis

This paper explores the interfaces between gapless quantum phases, particularly those with internal symmetries. It argues that these interfaces, rather than boundaries, provide a more robust way to distinguish between different phases. The key finding is that interfaces between conformal field theories (CFTs) that differ in symmetry charge assignments must flow to non-invertible defects. This offers a new perspective on the interplay between topology and gapless phases, providing a physical indicator for symmetry-enriched criticality.
Reference

Whenever two 1+1d conformal field theories (CFTs) differ in symmetry charge assignments of local operators or twisted sectors, any symmetry-preserving spatial interface between the theories must flow to a non-invertible defect.

Analysis

This paper provides a theoretical framework, using a noncommutative version of twisted de Rham theory, to prove the double-copy relationship between open- and closed-string amplitudes in Anti-de Sitter (AdS) space. This is significant because it provides a mathematical foundation for understanding the relationship between these amplitudes, which is crucial for studying string theory in AdS space and understanding the AdS/CFT correspondence. The work builds upon existing knowledge of double-copy relationships in flat space and extends it to the more complex AdS setting, potentially offering new insights into the behavior of string amplitudes under curvature corrections.
Reference

The inverse of this intersection number is precisely the AdS double-copy kernel for the four-point open- and closed-string generating functions.

Analysis

This article likely discusses the interaction of twisted light (light with orbital angular momentum) with matter, focusing on how the light's angular momentum is absorbed. The terms "paraxial" and "nonparaxial" refer to different approximations used in optics, with paraxial being a simpler approximation valid for light traveling nearly parallel to an axis. The research likely explores the behavior of this absorption under different conditions and approximations.

    This paper investigates the interplay between topological order and symmetry breaking phases in twisted bilayer MoTe2, a material where fractional quantum anomalous Hall (FQAH) states have been experimentally observed. The study uses large-scale DMRG simulations to explore the system's behavior at a specific filling factor. The findings provide numerical evidence for FQAH ground states and anyon excitations, supporting the 'anyon density-wave halo' picture. The paper also maps out a phase diagram, revealing charge-ordered states emerging from the FQAH, including a quantum anomalous Hall crystal (QAHC). This work is significant because it contributes to understanding correlated topological phases in moiré systems, which are of great interest in condensed matter physics.
