World sheets of spinning particles

open access: yes, 2017
The classical spinning particles are considered such that quantization of classical model leads to an irreducible massive representation of the Poincar\'e group.

Soft bounds for local triple products and the subconvexity‐QUE implication for GL2$\mathrm{GL}_2$

open access: yesMathematika, Volume 71, Issue 4, October 2025.
Abstract We give a soft proof of a uniform upper bound for the local factors in the triple product formula, sufficient for deducing effective and general forms of quantum unique ergodicity (QUE) from subconvexity.

Tropical conics for the layman [PDF]

open access: yes, 2008
We present a simple and elementary procedure to sketch the tropical conic given by a degree--two homogeneous tropical polynomial. These conics are trees of a very particular kind.

Analysis of density matrix embedding theory around the non‐interacting limit

open access: yesCommunications on Pure and Applied Mathematics, Volume 78, Issue 8, Page 1359-1410, August 2025.
Abstract This article provides the first mathematical analysis of the Density Matrix Embedding Theory (DMET) method. We prove that, under certain assumptions, (i) the exact ground‐state density matrix is a fixed‐point of the DMET map for non‐interacting systems, (ii) there exists a unique physical solution in the weakly‐interacting regime, and (iii ...

Rapid Design of Efficient Mn3O4‐Based Photocatalysts by Machine Learning and Density Functional Theory Calculations

open access: yesAdvanced Energy and Sustainability Research, Volume 6, Issue 7, July 2025.
A rapid design strategy is presented for efficient Al‐doped Mn3O4‐based photocatalysts by integrating density functional theory calculations, machine learning (ML) modeling, and experiments. The optimized Al0.5Mn2.5O4/35 wt%‐Ag3PO4 heterojunctions achieved a 27‐fold improvement in methylene blue degradation under visible light compared to pristine ...

Improving the Convergence of Markov Chains via Permutations and Projections

open access: yesRandom Structures &Algorithms, Volume 66, Issue 4, July 2025.
ABSTRACT This paper aims at improving the convergence to equilibrium of finite ergodic Markov chains via permutations and projections. First, we prove that a specific mixture of permuted Markov chains arises naturally as a projection under the KL divergence or the squared‐Frobenius norm.

Stabilized Krylov Subspace Recurrences via Randomized Sketching

open access: yesNumerical Linear Algebra with Applications, Volume 32, Issue 3, June 2025.
ABSTRACT Recurrences building orthonormal bases for polynomial Krylov spaces have been classically used for approximation purposes in various numerical linear algebra contexts. Variants aiming to limit memory and computational costs by using truncated recurrences often have convergence constraints.

Structure of hyperbolic polynomial automorphisms of C2${\mathbb {C}^2}$ with disconnected Julia sets

open access: yesProceedings of the London Mathematical Society, Volume 130, Issue 6, June 2025.
Abstract For a hyperbolic polynomial automorphism of C2$\mathbb {C}^2$ with a disconnected Julia set, and under a mild dissipativity condition, we give a topological description of the components of the Julia set. Namely, there are finitely many “quasi‐solenoids” that govern the asymptotic behavior of the orbits of all nontrivial components.

Singular Electromagnetics: From Phase Singularities to Optical Skyrmions and Beyond

open access: yesAdvanced Physics Research, Volume 4, Issue 5, May 2025.
Singular electromagnetics/optics studies multidimensional topological defects of electromagnetic fields (also known as optical singularities), including phase and polarization singularities, 3D singularities (e.g., optical skyrmions, merons, hopfions, knots, links, and Möbius strips), and even higher‐dimensional singularities.
