How tiny voids could make fusion targets more stable under powerful shockwaves

Picture two materials sandwiched together. The boundary between them may appear flat, but, in reality, it is full of tiny bumps and dents. Suddenly, the materials are hit with a shockwave. If that wave hits a bump in the material interface, it slows down. If it hits a dent, it accelerates forward. This imbalance creates […]

Generalized optical meta-spanners empower arbitrary light paths for multitasking optical manipulation

Have you ever wished to drive microscopic matter along an arbitrarily tailored trajectory instead of just a circle? That’s exactly what we set out to achieve.

Quantum model explains how single electrons cause damage inside silicon chips

Researchers in the UC Santa Barbara Materials Department have uncovered the elusive quantum mechanism by which energetic electrons break chemical bonds inside microelectronic devices—a detrimental process that slowly degrades performance over time. The discovery, published as an Editors’ Suggestion in Physical Review B, explains decades-old experimental puzzles and moves scientists closer to engineering more reliable […]

There’s a range of magic angles to study superconductivity in a twisted 2D semiconductor

Last year, tungsten diselenide (WSe2) had its magic moment. Two independent research groups discovered “magic angles” at which two atom-thin layers of the unique semiconductor, when twisted relative to one another into what’s known as a moire pattern, can superconduct electricity. Cory Dean and his colleagues at Columbia documented superconductivity at a 5° twist angle; […]

DESI completes planned 3D map of the universe and continues exploring

The Dark Energy Spectroscopic Instrument (DESI) has successfully completed the largest high-resolution 3D map of the universe ever made, a major milestone in understanding the force driving cosmic expansion. The milestone was reached when DESI’s 5,000 fiber-optic sensors captured their final scheduled observations, targeting a region of sky near the Little Dipper.

The moon might be more prone to fires

Engineers love a good practical challenge, especially when it comes to spaceflight. But there’s one particular challenge facing the crewed missions of the near future that scares mission planners above almost all others—fire. For decades, we’ve relied on a NASA test known as NASA-STD-6001B to screen material flammability for flight. But space is much more […]

Surprising link between metallicity and superconductivity uncovered in twisted trilayer graphene

Superconductivity is a state of matter characterized by an electrical resistance of zero, typically at very low temperatures. Past studies have found that in various materials, this unique state is accompanied by unusual electron arrangements.

Universal quantum protocol extracts maximum work without knowing a system’s state in advance

A new study published in Nature Communications has shown that in the asymptotic limit, extracting the maximum possible work from many copies of a quantum system does not require knowing exactly what state that system is in.

Bright quantum light emission achieved at room temperature in 2D semiconductors

A joint research team led by Professor Park Kyoung-Duck and Associate Director Suh Yung Doug of the Center for Multidimensional Carbon Materials within the Institute for Basic Science (IBS) has succeeded in realizing a high-efficiency quantum light source that emits bright lights even at room temperature. The study is published in the journal Science Advances. […]

Flat optics move toward market with 300-per-second metalens production
