Quantum batteries are energy-storing devices, governed by quantum mechanics, that promise high charging performance thanks to collective effects. Because of its experimental feasibility, the Dicke battery-which comprises N two-level systems coupled to a common photon mode-is one of the most promising designs for quantum batteries. However, the chaotic nature of the model severely hinders the extractable energy (ergotropy).

Monolayers of transition metal dichalcogenides (TMDs) offer inherent 2D confinement and possess significant exciton binding energies, making them promising candidates for achieving electric-field-based confinement of excitons without dissociation. Exploiting the valley degree of freedom associated with these confined states further broadens the prospects for exciton engineering.

- Seasonal influenza poses a public health challenge with socioeconomic impacts, and wastewater-based epidemiology (WBE) is a promising method for monitoring its spread and enhancing public health strategies.
- In a study conducted in Italy, wastewater samples were analyzed to detect influenza virus RNA, revealing a strong correlation between viral RNA loads and influenza-like illness cases reported in the community.
- The findings suggest that while WBE is not a substitute for traditional methods, it can significantly enhance the understanding of influenza dynamics and incidence trends.
Article Synopsis
- Topological photonics allows for light control that is resilient against manufacturing flaws, but past experiments have mostly worked at the vacuum wavelength level.* -
- This study demonstrates deep subwavelength topological edge states in a van der Waals heterostructure, achieving confinement in a volume much smaller than the corresponding free-space wavelength.* -
- The findings suggest potential applications in integrating various polaritonic materials, enhancing operational frequency ranges, and aligning with electronic systems.*
There is increasing evidence of the use of wastewater-based epidemiology to integrate conventional monitoring assessing disease symptoms and signs of viruses in a specific territory. We present the results of SARS-CoV-2 environmental surveillance activity in wastewater samples collected between September 2020 and July 2021 in 9 wastewater treatment plants (WTPs) located in central and western Sicily, serving over 570,000 residents. The presence of SARS-CoV-2, determined in 206 wastewater samples using RT-qPCR assays, was correlated with the notified and geo-referenced cases on the areas served by the WTPs in the same study period.
