Nanophotonics, Volume 15, Issue 10, 27 May 2026.Phase‐enabled nonlinear gating with unbalanced intensity (PENGUIN) enables reconstruction of the complete ultrafast optical field from one‐dimensional nonlinear interferometric autocorrelation traces. Combined with deep learning, the DeepPENGUIN framework enables real‐time spectral phase retrieval without spectrally resolved detection or iterative ...

Almost Hermitian Structures From Almost Contact Metric Manifolds and Their Curvature Properties
In this manuscript, we consider almost Hermitian manifolds and almost contact metric manifolds. We construct almost Hermitian manifolds from the product of almost contact metric manifolds with R by warped product.

Singular hermitian metrics on holomorphic vector bundles
Arkiv för Matematik, 2015 We introduce and study a notion of singular hermitian metrics on holomorphic vector bundles, following Berndtsson and P{ă}un. We define what it means for such a metric to be curved in the sense of Griffiths and investigate the assumptions needed in order to locally define the cuvature $Θ^h$ as a matrix of currents.

PATH INTEGRALS FOR QUASI-HERMITIAN HAMILTONIANS
, 2011 Inner products in quasi-Hermitian quantum theories, and hence probabilities, are defined through a metric that depends on the details of the Hamiltonians themselves.

Heat flow for the Yang-Mills-Higgs field and the Hermitian Yang-Mills-Higgs metric
, 2001 For a parameter lambda > 0, we study a type of vortex equations, which generalize the well-known Hermitian-Einstein equation, for a connection A and a section phi of a holomorphic vector bundle E over a Kahler manifold X.

Metric operator for the non-Hermitian Hamiltonian model and pseudo-super-symmetry
, 2013 We have obtained the metric operator Theta = exp T for the non-Hermitian Hamiltonian model H = omega (a(dagger)a + 1/2) + alpha (a(2) - a(dagger 2)). We also found the intertwining operator that connects the Hamiltonian to the adjoint of its pseudo-super-
