In a new study published in JCAP, Robson Christie, Jaewoo Joo, Greg Kaplanek, Vincent Vennin and David Wands used a simplified model to investigate what determines which vacuum a field may end up in within an expanding Universe.

n South Africa’s Karoo region, contemporary radio astronomy is meeting the astronomical knowledge of communities descended from the San. A practice insight published in JCOM proposes a model for dialogue between historical archives, local memory and moder
A study based on mathematical models shows that, when competing populations colonize new territory, greater fitness is not enough: position and expansion speed also matter.
A new version of the Daydreaming algorithm allows artificial memory systems to work reliably even with biased and imperfect data, like those found in the real world.
Nobel laureate Giorgio Parisi and physicist Francesco Zamponi, with the help of artificial intelligence, solve a mathematical problem that had remained open for more than a decade and document the entire process.
Why giving dark matter an extra attractive force does not necessarily lead to "clumpier matter”
A new study explores how transfer learning reduces the cost of cosmological simulations while revealing the risks of “negative transfer” in the search for physics beyond the standard model
Turning films into a gateway to science. New paper in JCOM
A simple physics-inspired model sheds light on how neural networks learn, offering new clues to the surprising efficiency and stability of modern AI systems
A study published in JCAP shows how a team of undergraduate students built a small-scale detector to search for axions, setting new limits on their properties with a low-cost experimental setup
