Quantization of Polaritons Confined in Dielectric Structures

open access: yesLaser &Photonics Reviews, EarlyView.
This study addresses the limitations of the Hopfield model of strong light‐matter coupling in the case of structured dieletrics. A method to derive quantum models in the polariton basis using Bogoliubov transformation and third quantization is introduced, demonstrating how to boost interaction strength and engineer nonlocal interactions for strongly ...

Theory of Supercritical Coupling and Generalized Bound States in the Continuum

open access: yesLaser &Photonics Reviews, EarlyView.
We develop a general theory of supercritical coupling and generalized bound states in the continuum (gBICs), revealing how interference between radiative and absorptive channels enables quality factors beyond conventional material‐loss limits. The framework unifies non‐Hermitian mode coupling, causality‐driven reactive interactions, and interference ...

Kernel Bounds for Parabolic Operators Having First‐Order Degeneracy at the Boundary

open access: yesMathematische Nachrichten, EarlyView.
ABSTRACT We study kernel estimates for parabolic problems governed by singular elliptic operators ∑i,j=1N+1qijDij+cDyy,cγ+1>0,γ=qN+1,N+1,$$\begin{equation*} \sum _{i,j=1}^{N+1}q_{ij}D_{ij}+c\frac{D_y}{y},\qquad \frac{c}{\gamma }+1>0, \quad \gamma =q_{N+1,N+1}, \end{equation*}$$in the half‐space R+N+1={(x,y):x∈RN,y>0}$\mathbb {R}^{N+1}_+=\lbrace (x,y ...

Improving Affordability and Accessibility for Socially‐Beneficial Services via Government Incentives

open access: yesNaval Research Logistics (NRL), EarlyView.
ABSTRACT Many socially‐beneficial services, like dental care, suffer from a dual challenge: Low affordability for citizens and long waiting times due to insufficient provider capacity. We model a government's problem of designing subsidy policies to address this issue.

Optimizing Household Waste Recycling Centre Network Reorganization in Hampshire

open access: yesNetworks, EarlyView.
ABSTRACT Local councils across the UK are facing sustained financial pressures, and Household Waste Recycling Centres (HWRCs) are being increasingly considered for closure to reduce expenditure. In 2024, Hampshire County Council, which operates the largest HWRC network in the UK, proposed closing either five or twelve existing sites.

Area‐restricted search under realistic constraints

open access: yesOikos, EarlyView.
Abstract Area‐restricted search (ARS) is one of the most influential and widely used concepts in foraging theory, capturing a simple rule by which animals intensify local search following a resource encounter. Because ARS performs well in many spatially structured environments, it serves as a basic model for interpreting movement patterns across taxa ...

Stabilising Routines in Complex Emergencies: How Basic Service Continuity Shapes Perceived Security

open access: yesPublic Administration and Development, EarlyView.
ABSTRACT This study examines how locally embedded actors describe the relationship between basic service continuity and perceived security in complex emergencies, with particular attention to the stabilisation of everyday routines. Using Proximity‐Predictability‐Attributability (PPA) as an analytic lens, we trace how interviewees relate access to water,

Environmental Footprint of Diffuse Emissions in European Functional Urban Areas

open access: yesSustainable Development, EarlyView.
ABSTRACT This paper quantifies the environmental footprint of diffuse air emissions across 776 European functional urban areas (FUAs) from 2005 to 2022 by coupling Copernicus Atmosphere Monitoring Service (CAMS) gridded inventories with the Environmental Footprint (EF) 3.1 framework.

Sustainable Business Models and Environmental Innovation Capacity: The Moderating Role of Board Effectiveness

open access: yesSustainable Development, EarlyView.
ABSTRACT Sustainable Business Models (SBMs) reflect the degree to which sustainability principles are embedded across firms' business model architectures. However, the mere adoption of these models does not guarantee improvements in environmental innovation capacity due to internal organizational inertia.

Promoting Climate‐Friendly Behaviour Under Cognitive and Coordination Constraints: A Multi‐Level Framework for Sustainable Development Governance

open access: yesSustainable Development, EarlyView.
ABSTRACT Despite widespread concern about climate change, climate‐friendly behaviour remains difficult to sustain in practice. This article argues that the core challenge lies less in insufficient motivation than in the cognitive and coordination demands imposed by prevailing decision environments.
