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

Note on Hamiltonicity of Basis Graphs of Even Delta‐Matroids
Journal of Graph Theory, Volume 109, Issue 4, Page 446-453, August 2025.ABSTRACT We show that the basis graph of an even delta‐matroid is Hamiltonian if it has more than two vertices. More strongly, we prove that for two distinct edges e and f sharing a common end, it has a Hamiltonian cycle using e and avoiding f unless it has at most two vertices or it is a cycle of length at most four.

Geophysical Research Letters, Volume 52, Issue 13, 16 July 2025.Abstract Discrepancies in historical global mean surface temperature (GMST) estimates largely stem from differences in bias corrections applied to sea surface temperature (SST) records. Here, using the amplitude of the diurnal cycle in SST, we provide evidence that wooden‐to‐canvas bucket transitions were mostly complete by the early 1900s, earlier ...

Improving the Convergence of Markov Chains via Permutations and Projections
Random 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.

Angewandte Chemie, Volume 137, Issue 24, June 10, 2025.Entropy‐driven competitive adsorption modulation in perovskite electrocatalysts enables hybrid conversion Zn–air batteries that couple sustainable energy storage and green chemical synthesis. Abstract Hybrid conversion Zn–air batteries (HC‐ZABs) epitomize a typical integrated energy storage and conversion device that advances green chemistry and ...
