Convergence properties of dynamic mode decomposition for analytic interval maps

open access: yesCommunications on Pure and Applied Mathematics, Volume 79, Issue 2, Page 179-206, February 2026.
Abstract Extended dynamic mode decomposition (EDMD) is a data‐driven algorithm for approximating spectral data of the Koopman operator associated to a dynamical system, combining a Galerkin method with N$N$ functions and a quadrature method with M$M$ quadrature nodes.

Dimer models and conformal structures

open access: yesCommunications on Pure and Applied Mathematics, Volume 79, Issue 2, Page 340-446, February 2026.
Abstract Dimer models have been the focus of intense research efforts over the last years. Our paper grew out of an effort to develop new methods to study minimizers or the asymptotic height functions of general dimer models and the geometry of their frozen boundaries.

Ideal MTL algebras(理想MTL代数)

open access: yesZhejiang Daxue xuebao. Lixue ban
Ideal theory plays a crucial role in investigating properties of MTL-algebras, which serves as the algebraic semantics for fuzzy logic systems based on left-continuous T-norms.

On Multilevel Energy‐Based Fragmentation Methods

open access: yesInternational Journal of Quantum Chemistry, Volume 126, Issue 3, January 30, 2026.
We investigate the working equations of energy‐based fragmentation methods and present ML‐SUPANOVA, a Möbius‐inversion‐based multilevel fragmentation scheme that enables adaptive, quasi‐optimal truncations to efficiently approximate Born‐Oppenheimer potentials across hierarchies of electronic‐structure methods and basis sets.

Generalized Surface Conductivity Model for Anisotropic Phonon Polaritons in van der Waals Slabs

open access: yesNanophotonics, Volume 15, Issue 2, 27 January 2026.
Herein, we report a generalized surface conductivity model which includes all waveguide polariton branches, by taking into account the out‐of‐plane dimension. Using this generalized 2D model can separate and examine each individual polaritonic mode in van der Waals slabs and further clarify their contributions in near‐field light matter interactions ...

Spatiotemporally Resolved Orbital Hall Effect in a Topological Semimetal

open access: yesAdvanced Materials, Volume 38, Issue 4, 16 January 2026.
Real‐space mapping of orbital angular momentum (OAM) transport is achieved using contact‐free polarimetric terahertz spectroscopy. This principle is applied to the topological semimetal Td‐WTe2, revealing the spatial separation of electrons into two distinct regions characterized by opposite out‐of‐plane OAM (±Lz).

Manipulating Individual Topological Solitons and Bisolitons in an Electronic System

open access: yesAdvanced Materials, Volume 38, Issue 3, 13 January 2026.
While localized topological modes in quantum materials promise loss‐less delivery of classical and quantum information, manipulating them individually has been challenging. This work succeeded in manipulating topological solitons formed along atomic wires on silicon surfaces with high reproducibility in various ways, including translating, transforming

Quantum GraviElectro Dynamics

open access: yesAnnalen der Physik, Volume 538, Issue 1, January 2026.
The BRST invariant Lagrangian of the gravitationally interacting U(1)$U(1)$ gauge theory, namely the Quantum GraviElectro Dynamics (QGED). The Yan–Mills theory with the Hilbert–Einstein gravitational Lagrangian, namely the Yang–Mills–Utiyama (YMU) theory, is defined and quantised using the standard procedure. The theory is perturbatively renormalisable,

Implicative algebras and Heyting algebras can be residuated lattices

open access: yes, 2017
The commutative residuated lattices were first introduced by M. Ward and R.P. Dilworth as generalization of ideal lattices of rings. Complete studies on residuated lattices were developed by H. Ono, T. Kowalski, P. Jipsen and C. Tsinakis. Also, the concept of lattice implication algebra is due to Y. Xu.

A Probabilistic Cut Finite Element Method With Random Field Generator and Bayesian Model Calibration for Flow Through Rough Cracks

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 1, Page 298-320, January 2026.
ABSTRACT A new model for the simulation of fluid flow through rough cracks is presented. The model combines a probabilistic cut finite element method (PCutFEM) to capture the unfitted boundary condition at the fluid interface, with a stochastic random field generator to represent the crack asperities.
