Scientists make sound-waves from a quantum vacuum at the Black Hole laboratory — ScienceDaily

Researchers have developed a new theory for observing a quantum vacuum that could lead to new insights into the behaviour of black holes.

The Unruh effect combines quantum physics and the theory of relativity. So far it has not been possible to measure or observe it, but now new research from a team led by the University of Nottingham has shed light on how this could be achieved using sound particles. The team’s research has been published today in the journal Physical Review Letters.

The Unruh effect suggests that if you fly through a quantum vacuum with extreme acceleration, the vacuum no longer looks like a vacuum: rather, it looks like a warm bath full of particles. This phenomenon is closely related to the Hawking radiation from black holes.

Cerebras Systems and National Energy Technology Laboratory Set New Compute Milestone

At Two Hundred Times the Speed of a Supercomputer, CS-1 Delivers Performance Unattainable with CPUs and GPUs

Cerebras Systems, the pioneer in high performance artificial intelligence (AI) compute, today announced record-breaking performance on a scientific compute workload. In collaboration with the Department of Energy’s National Energy Technology Laboratory (NETL), Cerebras demonstrated its CS-1 delivering speeds beyond what either CPUs or GPUs are currently able to achieve. Specifically, the CS-1 was 200 times faster than the Joule Supercomputer on the key workload of Computational Fluid Dynamics (CFD).

“NETL researchers and the Cerebras team collaborated to extend the frontier of what is possible,” said Dr. Brian J. Anderson, Lab Director at NETL. “This work at the intersection of supercomputing and AI will extend our understanding of fundamental scientific phenomena, including combustion and how to make combustion more efficient. Together, NETL and Cerebras are using innovative new computer architectures to further the NETL

Fermilab is partner in Quantum Science Center based at Oak Ridge National Laboratory | US Department of Energy Science News


DOE/Fermi National Accelerator Laboratory

In August, the U.S. Department of Energy announced the establishment of five National Quantum Information Science Research Centers. Fermilab is the lead laboratory for one of them, the Superconducting Quantum Materials and Systems Center, which joins together 20 institutions to bring about revolutionary advances in quantum computing and sensing with the goal of building and deploying a beyond-state-of-the-art quantum computer.

In a separate effort, Fermilab also plays a key role in another center — Oak Ridge National Laboratory’s Quantum Science Center, or QSC.

QSC unites Oak Ridge’s powerhouse capabilities in supercomputing and materials science with Fermilab’s world-class high-energy physics instrumentation and measurement expertise and facilities.

Drawing on their experience building and operating experiments in cosmology and particle physics and in quantum information science, the Fermilab team is engaging in QSC efforts to develop novel, advanced quantum technologies.

Air Force opens new laboratory to test satellite components

The Air Force Research Laboratory’s Space Vehicles Directorate will use the new facility to test advanced composite materials and structures.

WASHINGTON — The Air Force Research Laboratory is opening a $4 million facility focused on spacecraft component testing, AFRL announced Nov. 3.

The so-called Deployable structures Laboratory will be part of AFRL’s Space Vehicles Directorate. A ribbon-cutting ceremony was held Oct. 29 at Kirtland Air Force Base, New Mexico. Construction of the 7,000 square-foot laboratory began in December 2019. 

“I’m excited to have a facility that was specifically built for testing novel deployable space structures,” Benjamin Urioste, AFRL research engineer, said in a news release.

Urioste said the new facility will be used by AFRL to test advanced composite materials and structures, bringing “large satellite capability” to smaller satellites. He said the testing equipment will help AFRL reduce the risk of future missions by ensuring satellites are more reliable,

Exploring the source of stars and planets in a laboratory

A new method for verifying a widely held but unproven theoretical explanation of the formation of stars and planets has been proposed by researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL). The method grows from simulation of the Princeton Magnetorotational Instability (MRI) Experiment, a unique laboratory device that aims to demonstrate the MRI process that is believed to have filled the cosmos with celestial bodies.

Cosmic dust

The novel device, designed to duplicate the process that causes swirling clouds of cosmic dust and plasma to collapse into stars and planets, consists of two fluid-filled concentric cylinders that rotate at different speeds. The device seeks to replicate the instabilities that are thought to cause the swirling clouds to gradually shed what is called their angular momentum and collapse into the growing

Information Technology Laboratory employees win HENAAC awards > U.S. Army Corps of Engineers Headquarters > Story Article View

Christine Lozano and Dr. Alicia Ruvinsky, both members of the U.S. Army Engineer Research and Development Center Information Technology Laboratory team, were named winners of the Hispanic Engineer National Achievement Association Conference (HENAAC) 2020 Great Minds in STEM award.

HENAAC’s annual awards have recognized America’s top engineers and scientists from the Hispanic community for the past 31 years. Lozano was named a STEM hero, while Ruvinsky was honored for professional achievement.

“When I was younger, I was introduced to a drafting class by a female architect,” said Lozano. “It was through this drafting class that I realized that my appreciation for art and creativity could go hand in hand with my strength in math. As I kept looking around, I had male engineering influences, who I am so thankful for because they nurtured my goals and desires, but I never really had a female STEM influence. One of my dreams
