Coulomb branch algebras via symplectic cohomology

Journal of Topology, Volume 19, Issue 2, June 2026.
Abstract Let (M¯,ω)$(\bar{M}, \omega)$ be a compact symplectic manifold with convex boundary and c1(TM¯)=0$c_1(T\bar{M})=0$. Suppose that (M¯,ω)$(\bar{M}, \omega)$ is equipped with a convex Hamiltonian G$G$‐action for some connected, compact Lie group G$G$.

A Chain, a Bath, a Sink, and a Wall

Entropy, 2017
We numerically investigate out-of-equilibrium stationary processes emerging in a Discrete Nonlinear Schrödinger chain in contact with a heat reservoir (a bath) at temperature T L and a pure dissipator (a sink) acting on opposite edges.

Geometry of Supergravity and the Batalin–Vilkovisky Formulation of the N=1$\mathcal N=1$ Theory in Ten Dimensions

Fortschritte der Physik, Volume 74, Issue 5, May 2026.
ABSTRACT We provide full details of a BV formulation of N=1$\mathcal N=1$ supergravity in 10 dimensions, to all orders in fermions, built from the generalised geometry description of the theory. In contrast to standard treatments, we introduce neither the degrees of freedom corresponding to orthonormal frames for the metric nor the local Lorentz ...

Chaos dynamics of charged particles near Gibbons-Maeda-Garfinkle-Horowitz-Strominger black holes

Nuclear Physics B
The Gibbons-Maeda-Garfinkle-Horowitz-Strominger (GMGHS) dilatonic black hole, a key solution in low-energy string theory, exhibits previously unexplored chaotic dynamics for charged test particles under electromagnetic influence.

Quantum Theory of Distributed‐Feedback Parametric Amplifiers and Oscillators

Advanced Quantum Technologies, Volume 9, Issue 5, May 2026.
A new class of quantum light source is emerging from optical parametric cavities formed by Bragg reflectors, a so‐called distributed‐feedback design. Such devices are especially promising for quantum technologies such as sensing. Here, an analytic quantum model of these sources reveals their key properties, such as the parametric oscillation threshold,

The Lp$L^p$‐diameter of the space of contractible loops

Bulletin of the London Mathematical Society, Volume 58, Issue 5, May 2026.
Abstract We prove that the space of contractible simple loops of a given fixed area in any compact oriented surface has infinite diameter as a homogeneous space of the group of area‐preserving diffeomorphisms endowed with the Lp$L^p$‐metric. As a special case, this resolves the Lp$L^p$‐metric analog of the well‐known question in symplectic topology ...

Leveraging Hamiltonian neural flow for robust single-cell multi-omics integration: application to Alzheimer’s disease

Frontiers in Genetics
Alzheimer’s disease (AD) progression involves complex molecular interactions across multiple biological layers, yet integrating high-dimensional single-cell multi-omics data remains computationally challenging.

Which singular tangent bundles are isomorphic?

Journal of the London Mathematical Society, Volume 113, Issue 5, May 2026.
Abstract Logarithmic and b$ b$‐tangent bundles provide a versatile framework for addressing singularities in geometry. Introduced by Deligne and Melrose, these modified bundles resolve singularities by reframing singular vector fields as well‐behaved sections of these singular bundles.
