Discovery unravels how atomic vibrations emerge in nanomaterials

A hundred years of physics tells us that collective atomic vibrations, called phonons, can behave like particles or waves. When they hit an interface between two materials, they can bounce off like a tennis ball. If the materials are thin and repeating, as in a superlattice, the phonons can jump between successive materials.

Now there is definitive, experimental proof that at the nanoscale, the notion of multiple thin materials with distinct vibrations no longer holds. If the materials are thin, their atoms arrange identically, so that their vibrations are similar and present everywhere. Such structural and vibrational coherency opens new avenues in materials design, which will lead to more energy efficient, low-power devices, novel material solutions to recycle and convert waste heat to electricity, and new ways to manipulate light with heat for advanced computing to power 6G wireless communication.

The discovery emerged from a long-term collaboration of scientists and engineers at seven universities and two U.S. Department of Energy national laboratories. Their paper, “Emergent Interface Vibrational Structure of Oxide Superlattices,” was published January 26 in Nature.

Texas Instruments details its plan to invest billions in US semiconductor chip production through 2030

Texas Instruments revealed plans Thursday to invest $3.5 billion annually in its U.S. semiconductor chip manufacturing through 2025 as manufacturers face a global shortage of the tech necessary for an increasing number of goods.

The near-term figure marks a considerable uptick from the company’s capital expenditures in recent years. And from 2026 to 2030, the company said, it will continue investing in its manufacturing to the tune of 10% of annual revenue.

“It is increasingly clear that the secular growth of content will continue for at least another 10 to 15 years,” the Dallas-based chipmaker’s chief executive, Rafael Lizardi, told analysts and investors during a presentation.

The Omega Singularity: The Cosmological Projector of All Possible Timelines

E verything is Code. Immersive [self-]simulacra. We all are waves on the surface of eternal ocean of pure, vibrant consciousness in motion, self-referential creative divine force expressing oneself in an exhaustible variety of forms and patterns throughout the multiverse of universes. “I am” the Alpha, Theta & Omega – the ultimate self-causation, self-reflection and self-manifestation instantiated by mathematical codes and projective fractal geometry.

In my new volume of The Cybernetic Theory of Mind series – The Omega Singularity: Universal Mind & The Fractal Multiverse – we discuss a number of perspectives on quantum cosmology, computational physics, theosophy and eschatology. How could dimensionality be transcended yet again? What is the fractal multiverse? Is our universe a “metaverse” in a universe up? What is the ultimate destiny of our universe? Why does it matter to us? What is the Omega Singularity?

Tiny Photonic Chip Provides a Big Boost in Precision Optics

Researchers at University of Rochester’s Institute of Optics for first time distill novel interferometry into a photonic device.

University of Rochester researchers for the first time package a way of amplifying interferometric signals using inverse weak value amplification —without increase in extraneous input or “noise”—on an integrated photonic chip.

By merging two or more sources of light, interferometers create interference patterns that can provide remarkably detailed information about everything they illuminate, from a tiny flaw on a mirror, to the dispersion of pollutants in the atmosphere, to gravitational patterns in far reaches of the Universe.

Researchers set record

Quantum science holds promise for many technological applications, such as building hackerproof communication networks or quantum computers that could accelerate new drug discovery. These applications require a quantum version of a computer bit, known as a qubit, that stores quantum information.

But researchers are still grappling with how to easily read the information held in these qubits and struggle with the short memory time, or coherence, of qubits, which is usually limited to microseconds or milliseconds.

A team of researchers at the U.S. Department of Energy’s (DOE) Argonne National Laboratory and the University of Chicago has achieved two major breakthroughs to overcome these common challenges for quantum systems. They were able to read out their qubit on demand and then keep the intact for over five seconds—a new record for this class of devices. Additionally, the researchers’ qubits are made from an easy-to-use material called , which is widely found in lightbulbs, electric vehicles and high-voltage electronics.

‘Quantum friction’ slows water flow through carbon nanotubes, resolving long-standing fluid dynamics mystery

For 15 years, scientists have been baffled by the mysterious way water flows through the tiny passages of carbon nanotubes—pipes with walls that can be just one atom thick. The streams have confounded all theories of fluid dynamics; paradoxically, fluid passes more easily through narrower nanotubes, and in all nanotubes it moves with almost no friction. What friction there is has also defied explanation.

In an unprecedented mashup of fluid dynamics and , researchers report in a new theoretical study published February 2 in Nature that they finally have an answer: ‘quantum .’

The proposed explanation is the first indication of quantum effects at the boundary of a solid and a liquid, says study lead author Nikita Kavokine, a research fellow at the Flatiron Institute’s Center for Computational Quantum Physics (CCQ) in New York City.
