The researchers originally thought the lithium would be best housed in a “metal box” with an opening at the top. The plasma would flow into the gap so the lithium could dissipate the heat of the plasma before reaching the metal walls. Now, the researchers say a cave—geometrically just the inner half of a box—full of lithium vapor would be simpler than a box. The difference is more than just semantics: It impacts where the lithium travels and how effectively it dissipates heat.

“For years, we thought we needed a full, four-sided box, but now we know we can make something much simpler,” said Emdee. Data from new simulations pointed them in a different direction when the research team realized they could contain the lithium just as well if they cut their box in half. “Now we call it the cave,” Emdee said.

In the cave configuration, the device would have walls on the top, bottom and side closest to the center of the tokamak. This optimizes the path for the evaporating lithium, setting it on a better course for capturing the most heat from the private flux region while minimizing the complexity of the device.

Many fundamental processes of life, and their synthetic counterparts in nanotechnology, are based on the autonomous assembly of individual particles into complex patterns. LMU physicist Professor Erwin Frey, Chair of Statistical and Biological Physics at LMU Munich and member of the ORIGINS Excellence Cluster, investigates the fundamental principles of this self-organization.

The rapid development of technologies such as the internet, mobile communications, and artificial intelligence has dramatically increased the demand for high-capacity communication systems. Among various solutions, mode-division multiplexing (MDM) has emerged as a crucial technique, utilizing spatial modes like orbital angular momentum (OAM) to enhance communication capacity.

Solution-processed semiconductor nanocrystals are also called colloidal quantum dots (QDs). While the concept of size-dependent quantum effects had long been known to physicists, a sculpture of the theory into real nanodimensional objects remained impossible till the discovery of QDs. The size-dependent colors of QDs are essentially naked-eye, ambient-condition visualizations of the quantum size effect.

Governments, medical institutions and other bodies require accurate models on health-related matters in order to better organize their activities.

As the International Space Station is phased out, a new generation of commercial space stations from private companies will take its place.

I expect that space-based atom interferometry will lead to exciting new discoveries and fantastic quantum technologies impacting everyday life, and will transport us into a quantum future.

“Both TOI-1408 b and TOI-1408 c are incredibly close to their parent star compared to the planets in our solar system,” research lead author Judith Korth of Lund University told Space.com. “Imagine our solar system, but instead, Jupiter is orbiting very close to the sun nearly every four days, one-twentieth of the period of Mercury.

This is already very close to the star, and still, we detected another planet even closer to the star that interacts strongly with its big neighbor, causing their orbits to wobble in ways we’ve never seen before.

This engine was predicted by Edison 200 years ago, and now has been created: It’s neither electric nor hydrogen, but something miles ahead.
