Entangled quantum Stirling heat engine based on two particles Heisenberg model with Dzyaloshinskii-Moriya interaction

open access: yesFrontiers in Physics
Quantum heat engines have attracted significant attention in recent years due to their potential to surpass classical thermodynamic limits by leveraging quantum effects such as entanglement and coherence. In this study, we analyze a quantum Stirling heat

Leveraging Biodiversity Net Gain to address invertebrate declines in England

open access: yesInsect Conservation and Diversity, EarlyView.
Biodiversity Net Gain (BNG) is a new approach to infrastructural development in England, mandating that developers achieve a 10% BNG by enhancing and creating habitats. As currently implemented, BNG risks creating smaller, homogeneous, structurally simple and poorly connected habitats.

‘I Can Just Do Work I'm Paid to Do’: Hybrid Work and Tertiary Labour Time Gains

open access: yesIndustrial Relations Journal, EarlyView.
ABSTRACT This paper adopts a moral economy framework to analyse the unique and collective experience of remote work during the UK pandemic lockdowns. Through analysis of qualitative interviews with workers based at home during periods of lockdown, we explore how this offered workers a new opportunity to evaluate a particular type of work ...

Representing, Re‐presenting, or Producing the Past? Memory Work amongst Museum Employees

open access: yesJournal of Management Studies, EarlyView.
Abstract Though it is widely understood that the past can be an important resource for organizations, less is known about the micro‐level skills and choices that help to materialize different representations of the past. We understand these micro‐level skills and choices as a practice: ‘memory work’ – a banner term gathering various activities that ...
