Solid-state physics: Probing the geometry of energy bands

Posted by in categories: computing, mobile phones, particle physics, quantum physics

Scientists at Ludwig-Maximilians-Universitaet (LMU) in Munich and the Max Planck Institute for Quantum Optics (MPQ) have devised a new interferometer to probe the geometry of band structures.

The geometry and topology of electronic states in solids play a central role in a wide range of modern condensed-matter systems, including graphene and topological insulators. However, experimentally accessing this information has proven to be challenging, especially when the bands are not well isolated from one another. As reported by Tracy Li et al. in last week’s issue of Science (Science, May 27, 2016, DOI: 10.1126/science.aad5812), an international team of researchers led by Professor Immanuel Bloch and Dr. Ulrich Schneider at LMU Munich and the Max Planck Institute of Quantum Optics has devised a straightforward method with which to probe band geometry using ultracold atoms in an optical lattice. Their method, which combines the controlled transport of atoms through the energy bands with atom interferometry, is an important step in the endeavor to investigate geometric and topological phenomena in synthetic band structures.

A wide array of fundamental issues in condensed-matter physics, such as why some materials are insulators while others are metals, can be understood simply by examining the energies of the material’s constituent electrons. Indeed, band theory, which describes these electron energies, was one of the earliest triumphs of quantum mechanics, and has driven many of the technological advances of our time, from the computer chips in our laptops to the liquid-crystal displays on our smartphones. We now know, however, that traditional band theory is incomplete.

What Will Electronics & Semiconductors Be Like In 100 Years?

Posted by in categories: computing, electronics, information science, nanotechnology, singularity

When I 1st read this headline, I had to pause and ask myself “was the article’s author informed at all on QC?” especially given China’s own efforts much less D-Wave, Google, and University of Sydney. And, then I read the article and I still have to wonder if the author is on top of the emerging technologies such as BMI, graphene, QC, and other nanotechnology that are already being tested to go live in the next 7 to 10 years plus much of the content is very superficial at best. I am glad that the author did put the tid bit on Singularity as the endpoint state; however, that is pretty well known. Nonetheles, sharing to let you be the judge.


For decades, we relied on silicon as the semiconductor for our computer chips. But now, working at nanometer scales, it looks like physical limitations may end the current methods to include more and more processing power onto each individual chip.

Many companies are making billion-dollar investments to continue scaling down semiconductor technology. The pressures of big data and cloud computing are pushing the limits of the current semiconductor technology in terms of bandwidth, memory, processing speed, and device power consumption.

The case for black holes being nothing but holograms just got even stronger

Posted by in categories: cosmology, physics

If anything can sum up just how little we truly know about the Universe, it’s black holes.

We can’t see them because not even light can escape their gravitational pull, we have no idea what they’re made of, and where does everything inside go once a black hole dies?

Physicists can’t even agree on whether black holes are massive, three-dimensional behemoths, or just two-dimensional surfaces that are projected in 3D just like a hologram.

Aimed at the big boys, India’s “Google tax” could end up hurting the small and vulnerable — By Suneera Tandon and Manu Balachandran | Quartz

“It’s been dubbed the Google tax, but it will likely hit every global internet company operating in India—and, in turn, the country’s fledgling startup and digital advertising ecosystems.”

Elon Musk goes on a ‘machines building machines’ rant about the future of manufacturing

Posted by in categories: Elon Musk, engineering, transportation

Tesla’s 2016 Shareholders Meeting yesterday was an unusual one. CEO Elon Musk and CTO JB Straubel were on stage for close to 4 hours and went through the bulk of Tesla’s history – recounting stories from the early days with longtime employees of the automaker.

We already reported on important nuggets of information the execs released about the Gigafactory and the Model 3 during the event, but what probably stands out the most from the event – from my perspective at least – is Musk’s rant about the importance of the “machine that makes the machine.”

The CEO said that he recently – in the last 2 or 3 months – came to the realization that the potential for improvement is at least a factor of 10 greater in manufacturing vehicles than in the actual vehicle engineering.

Vitamin Found To Increase Lifespan and Halt Aging In Muscle Tissues

Posted by in categories: biotech/medical, life extension

Scientists have long used NAD+ as a powerful anti-aging tool. While trying to find a cure for aging, scientists increased the levels of NAD+ within the mitochondria. The mitochondria responded by increasing their performance and energy, which effectively neutralizes the effects of aging.

Lead researcher Johan Auwerx explained that “this work could have very important implications in the field of regenerative medicine,” adding that it may one day be possible to bypass surgery and repair the body with a dietary supplement.

Specifically, nicotinamide riboside “effectively delayed early- and late-stage disease progression, by robustly inducing mitochondrial biogenesis in skeletal muscle and brown adipose tissue, preventing mitochondrial ultrastructure abnormalities and [mitochondrial DNA] deletion formation.”
