Observation of quantized heating in quantum matter

Posted by in categories: energy, law, mathematics, quantum physics

Shaking a physical system typically heats it up, in the sense that the system continuously absorbs energy. When considering a circular shaking pattern, the amount of energy that is absorbed can potentially depend on the orientation of the circular drive (clockwise/anti-clockwise), a general phenomenon known as circular dichroism.

In 2017, Nathan Goldman (ULB, Brussels), Peter Zoller (IQOQI, Innsbruck) and coworkers predicted that can be quantized in (heating is then constrained by strict integers) forming a “topological state.” According to this , the quantization of energy absorption upon circular driving can be directly related to topology, a fundamental mathematical concept that characterizes these intriguing states of matter.

Writing in Nature Physics, the experimental group of Klaus Sengstock and Christof Weitenberg (Hamburg), in collaboration with the team of Nathan Goldman, reports on the first observation of quantized circular dichroism. Following the theoretical proposal of Goldman, Zoller et al., the experimentalists realized a topological state using an ultracold atomic gas subjected to , and studied its heating properties upon circular shaking of the gas. By finely monitoring the heating rates of their system, for a wide range of driving frequencies, they were able to validate the quantization law predicted by Goldman, Zoller et al. in 2017, in agreement with the underlying topological state realized in the laboratory.

Giant Wind Power Transmission Project Could Spark New Wind Rush In Wind Belt

Posted by in category: energy

Wow, anybody remember the Grain Belt Express? No? No wonder! The massive 700-mile wind power transmission project in the US Midwest has been on the boards since at least 2011. It got off to a promising start but suffered death by a thousand cuts when state officials in Missouri balked.

Well, it looks like the naysayers forgot to cut off its head or at least sever the spinal cord, because the Grain Belt Express could come back to walk the Earth once more.

Talga reports positive test results on its graphene silicon Li-ion battery anode project

Posted by in categories: energy, materials

Talga Resources has revealed new test results on the ongoing optimization of its graphene silicon Li-ion battery anode product, Talnode™- Si. According to Talga, the battery anode product returns further performance gains, now delivering ~70% more energy density than commercial graphite-only anodes.

The product reportedly provides a “drop in” solution for improving current Li-ion battery performance. Commercial samples under confidentiality and material transfer agreements are scheduled to commence delivery around the end of February 2019 — recipients are said to include some of the world’s largest electronic corporations.

For your convenience, a search was performed using the query ‘talga reports positive test results its graphene silicon li ion battery anode project talnode si’:

China to test magnetized plasma artillery

Posted by in categories: energy, military

The Chinese military is looking to procure test systems for magnetized plasma artillery, according to a notice on the People’s Liberation Army (PLA) weapon and equipment procurement website last week.

Released on Wednesday and due expire on Thursday, the notice invites tenders for a theory-testing and a launch system for magnetized plasma artillery.

Although the weapon sounds as if it comes from a sci-fi movie, it will probably not shoot high-energy plasma but ultra-high velocity cannon shells.

Plans for first Chinese solar power station in space revealed

Posted by in categories: energy, space, sustainability, transportation

Electric cars could be charged at any time and any place.

It could reliably supply energy 99 per cent of the time, at six-times the intensity of solar farms on earth, he said.

Chinese scientists first plan to build and launch small to medium-sized solar power stations to be launched into the stratosphere to generate electricity, between 2021 and 2025.

NASA posts image of ghostly blue objects, deep in the cosmos

Posted by in categories: energy, space

When a star is born, a chaotic light show ensues.

NASA’s long-lived Hubble Space Telescope captured vivid bright clumps moving through the cosmos at some 1,000 light years from Earth. The space agency called these objects clear “smoking gun” evidence of a newly formed star — as new stars blast colossal amounts of energy-rich matter into space, known as plasma.

Seen as the vivid blue, ephemeral clumps in the top center of the new image below, these are telltale signs of an energy-rich gas, or plasma, colliding with a huge collection of dust and gas in deep space.

Scottish space firm unveils world’s largest 3D printed rocket engine

Posted by in categories: 3D printing, energy, engineering, satellites

Scottish space firm Orbex has unveiled an engineering prototype of a rocket that’s at the heart of plans to develop a UK satellite launch capability.

The company, which is involved in plans to develop the UK’s first spaceport in Sutherland, Scotland unveiled the rocket at the opening of its new headquarters and rocket design facility in Forres in the Scottish Highlands.

Designed to deliver small satellites into Earth’s orbit, Orbex Prime is a two-stage rocket that’s claimed to be up to 30% lighter and 20% more efficient than any other vehicle in the small launcher category. It is also the first commercial rocket engine designed to work with bio-propane, a clean-burning, renewable fuel source that cuts carbon emissions by 90% compared to fossil hydrocarbon fuels.
