Nonlocal electrodynamics of two‐dimensional anisotropic magnetoplasmons

Nanophotonics, Volume 14, Issue 25, Page 4495-4511, December 2025.
Abstract We present a hydrodynamic model, grounded in Madelung’s formalism, to describe collective electronic motion in anisotropic materials. This model incorporates nonlocal contributions from the Thomas–Fermi quantum pressure and quantum effects arising from the Bohm potential.

Geometric phases and coherent states for commensurate bichromatic polarization and astigmatic cavities

Nanophotonics, Volume 14, Issue 24, Page 4285-4299, December 2025.
Abstract Both the polarization state of coherent bichromatic fields produced by harmonic generation and a class of anisotropic paraxial optical cavities are examples of commensurate two‐dimensional harmonic oscillators. The geometric phase for these systems is studied here, both in the classical/ray and quantum/wave regimes. The quantum geometric phase

Increasing entanglement between Gaussian states by coherent photon subtraction

, 2007
We experimentally demonstrate that the entanglement between Gaussian entangled states can be increased by non-Gaussian operations. Coherent subtraction of single photons from Gaussian quadrature-entangled light pulses, created by a non-degenerate ...

Tunable BIC metamaterials with Dirac semimetals

Nanophotonics, Volume 14, Issue 27, Page 4875-4925, December 2025.
Abstract Proposed by von Neuman and Wigner in 1929, bound states in the continuum (BIC) exhibit the merits of ultrahigh Q–factor and strongly confined modes, solving the inherent high dissipation of metamaterials (MMs) and plasmonic devices. Dirac semimetal (DSM) possesses the advantages of high carrier mobility and outstanding tunable properties ...

Density‐functional tight binding meets Maxwell: unraveling the mysteries of (strong) light–matter coupling efficiently

Nanophotonics, Volume 14, Issue 27, Page 4941-4955, December 2025.
Abstract Controlling chemical and material properties through strong light–matter coupling in optical cavities has gained considerable attention over the past decade. However, the underlying mechanisms remain insufficiently understood, and a significant gap persists between experimental observations and theoretical descriptions.

Wigner-Weyl isomorphism for quantum mechanics on Lie groups

, 2004
The Wigner-Weyl isomorphism for quantum mechanics on a compact simple Lie group $G$ is developed in detail. Several New features are shown to arise which have no counterparts in the familiar Cartesian case.

Programming Defects and Cavities into Colloidal Crystals Engineered With DNA

Advanced Materials, Volume 37, Issue 41, October 16, 2025.
Seed‐mediated crystallization is adapted for colloidal crystals to design cavities and defect architectures through chemically programmed DNA sequences and appropriate seed particle geometry. This synthetic approach combines tenets from both atomic and colloidal crystallization to deliberately control defect formation in superlattices and enables the ...

Average‐Case Matrix Discrepancy: Satisfiability Bounds

Random Structures &Algorithms, Volume 67, Issue 3, October 2025.
ABSTRACT Given a sequence of d×d$$ d\times d $$ symmetric matrices {Wi}i=1n$$ {\left\{{\mathbf{W}}_i\right\}}_{i=1}^n $$, and a margin Δ>0$$ \Delta >0 $$, we investigate whether it is possible to find signs (ε1,…,εn)∈{±1}n$$ \left({\varepsilon}_1,\dots, {\varepsilon}_n\right)\in {\left\{\pm 1\right\}}^n $$ such that the operator norm of the signed sum ...

Deterministic creation of entangled atom-light Schr\"odinger-cat states

, 2019
Quantum physics allows for entanglement between microscopic and macroscopic objects, described by discrete and continuous variables, respectively. As in Schr\"odinger's famous cat gedanken experiment, a box enclosing the objects can keep the entanglement

MUMOTT: a Python package for the analysis of multi‐modal tensor tomography data

Journal of Applied Crystallography, Volume 58, Issue 5, Page 1834-1845, October 2025.
The MUMOTT Python package facilitates the analysis of small‐ and wide‐angle X‐ray scattering tensor tomography data, using CPU and GPU acceleration to simplify complex computational tasks. Designed for ease of use, extensibility and efficiency, MUMOTT aims to lower barriers to adopting tensor tomography methods within the wider research community.Small‐
