Low‐Loss Polarization‐Maintaining Router for Single and Entangled Photons at a Telecom Wavelength
Advanced Quantum Technologies, EarlyView.A novel electro‐optic routing of arbitrarily polarized single photons and, crucially, multi‐photon entangled states is demonstrated. Utilizing optics with near‐normal incidence and cross‐aligned electro‐optic crystals, low‐loss polarization‐maintaining routing is achieved with a minimal number of components.

Dynamical Phase Transitions in Open Quantum Walks
Advanced Quantum Technologies, EarlyView.This work investigates dynamical phase transitions in discrete‐time quantum systems, highlighting the emergence of first‐ and second‐order transitions depending on whether detailed balance is preserved or broken. Using minimal quantum networks and quantum walks with internal degrees of freedom, the study reveals how spectral properties of the ...

A new class of non-Kähler metrics
Complex ManifoldsWe study the stability at blow-ups and deformations of a class of Hermitian metrics whose fundamental two-form ω\omega satisfies the condition ∂∂¯ωk=0\partial \bar{\partial }{\omega }^{k}=0, for any kk between 1 and n−1n-1 (where nn is the complex ...

International Journal of Robust and Nonlinear Control, EarlyView.ABSTRACT We review some known bounds on the eigenvalues of a matrix and use similar techniques to derive bounds for the class of nonlinear eigenproblems and, as a special case, the eigenvalues for LTI systems with delays. We present two classes of results.

Topological Polaritonic Metamaterials Realized in Bulk Transition Metal Dichalcogenide Crystals
Small Structures, EarlyView.Monolithic all‐van der Waals materials‐based polaritonic topological insulators are introduced and demonstrated that support robust boundary modes for extreme confinement and robust propagation of strongly coupled exciton‐photon hybrid particles, which are readily tunable with temperature. These monolithic polaritonic topological metasurfaces can serve

Journal of Microscopy, EarlyView.Abstract In the domain of battery research, the processing of high‐resolution microscopy images is a challenging task, as it involves dealing with complex images and requires a prior understanding of the components involved. The utilisation of deep learning methodologies for image analysis has attracted considerable interest in recent years, with ...

Exponential actions defined by vector configurations, Gale duality, and moment‐angle manifolds
Bulletin of the London Mathematical Society, EarlyView.Abstract Exponential actions defined by vector configurations provide a universal framework for several constructions of holomorphic dynamics, non‐Kähler complex geometry, toric geometry and topology. These include leaf spaces of holomorphic foliations, intersections of real and Hermitian quadrics, the quotient construction of simplicial toric ...
