CCNY physicists make quantum emitter discovery in diamonds

2025-09-03
(Press-News.org) Researchers at The City College of New York have shown how a quantum emitter, the nitrogen-vacancy (NV) center in diamond, interacts in unexpected ways with a specially engineered photonic structure when moved around with a scanning tip. The study, led by Carlos A. Meriles, Martin and Michele Cohen Professor of Physics in the Division of Science and entitled “Emission of Nitrogen–Vacancy Centres in Diamond Shaped by Topological Photonic Waveguide Modes,” appears in the journal Nature Nanotechnology.

What has long been considered a drawback of the NV center—its broad and messy emission spectrum—turns out to enable a new type of coupling that reshapes its light in ways not seen before. This discovery has fundamental importance for quantum information technologies, since such coupling could help overcome long-standing challenges like spectral diffusion and open pathways toward robust spin–photon and spin–spin entanglement on a chip. 

At the same time, the work demonstrates a novel sensing capability: by analyzing the NV emission, the team could reconstruct detailed, polarization-resolved images of the photonic modes with remarkable contrast. 

“Beyond photonic structures, this polarization sensitivity could eventually be applied to detecting chiral molecules, which are central to biology and medicine,” said Meriles.

He added that follow-up research will continue along both directions—probing quantum emitter–structure interactions more deeply and developing new sensing applications based on the same principles.

Loneliness is bad for health and wealth in the U.K.

2025-09-03
In the U.K., 4 in 10 citizens identify as being lonely at least some of the time, and people who report being often lonely incur about £850 more in annual National Health Service costs than their non-lonely counterparts, according to a study published September 3, 2025 in the open-access journal PLOS One by Nia Morrish from the University of Exeter, U.K., and colleagues. The World Health Organization recognizes loneliness as a ‘priority public health problem.’ Research supports this claim, but the effect of loneliness on healthcare costs remains largely unknown. Morrish and colleagues analysed the Understanding Society U.K. Household Longitudinal ...

Climate change is making rollercoaster harvests the new normal

2025-09-03
From corn chips to tofu, climate change is messing with the menu. A new global study led by the University of British Columbia shows that hotter and drier conditions are making food production more volatile, with crop yields swinging more sharply from year to year. For some, it may mean pricier burgers; for others, it can bring financial strain and hunger. Published today in Science Advances, the study is the first to show at a global scale how climate change is affecting yield swings of three of the world’s most important food crops: corn, soybean and sorghum. For every degree of warming, year-to-year ...

Misdirected: Increased dementia risk associated with errors of the 'brain’s compass'

2025-09-03
Individuals with an increased risk for dementia due to Alzheimer’s disease can have impaired spatial orientation skills. DZNE researchers come to this conclusion based on a study involving around 100 older adults who were tasked with determining their position within a virtual environment. In this, participants with “subjective cognitive decline” (SCD) – a risk factor for Alzheimer’s disease – performed worse than members of the control group. In contrast, there were no significant differences ...

Sip smarter: Apple juice effects on oral health are short-lived, study suggests

Vegan dog food provides similar nutrients to meat-based diets, new study finds

2025-09-03
A new study, led by experts at the University of Nottingham, has found that vegan diets for dogs sold in the UK provide similar nutrition to meat-based diets. The study, led by Rebecca Brociek from the School of Veterinary Medicine and Science, and published in PLOS One, highlights the importance of a balanced and nutritional diet for our canine companions. Dogs, like humans, are omnivores and require specific nutrients rather than specific ingredients. As plant-based diets gain popularity in human nutrition, the pet food industry is following suit with vegan diets becoming ...
