Cooperativity and entanglement pave way for ground-state cooling using nitrogen vacancy centers

Posted by in categories: engineering, nanotechnology, particle physics, quantum physics

Center for Nanoscale Materials researchers present a quantum model for achieving ground-state cooling in low frequency mechanical resonators and show how cooperativity and entanglement are key factors to enhance the cooling figure of merit.

A resonator with near-zero thermal noise has better performance characteristics in nanoscale sensing, quantum memories, and quantum information processing applications. Passive cryogenic cooling techniques, such as dilution refrigerators, have successfully cooled high-frequency resonators but are not sufficient for lower frequency systems. The optomechanical effect has been applied successfully to cool low-frequency systems after an initial cooling stage. This method parametrically couples a mechanical resonator to a driven optical cavity, and, through careful tuning of the drive frequency, achieves the desired cooling effect. The optomechanical effect is expanded to an alternative approach for ground-state cooling based on embedded solid-state defects. Engineering the atom-resonator coupling parameters is proposed, using the strain profile of the mechanical resonator allowing cooling to proceed through the dark entangled states of the two-level system ensemble.

New Wearable Respiratory Sensor Will Monitor a Child’s Every Breath

Posted by in categories: biotech/medical, engineering, wearables

Michelle Khine is a professor of biomedical engineering at the University of California, Irvine. Nine months ago, her newborn son was hospitalized for complications during childbirth and was admitted to the neonatal intensive care unit (NICU). While in the NICU, her son was connected to several machines that were supplying oxygen and monitoring his breathing.


A biomedical engineering research team from the University of California has developed a new wearable respiratory sensor to monitor children with chronic pulmonary conditions. The design was built with inspiration from a favorite childhood toy, Shrinky Dinks.

Elon Musk: Mars Base Will Have “Outdoorsy, Fun Atmosphere”

Posted by in categories: Elon Musk, engineering, environmental, food, space

In an interview newly published by Popular Mechanics, SpaceX CEO Elon Musk shared his thoughts on colonizing Mars — from how the first settlers will grow food to the friendly vibe he envisions at the first base on the Red Planet.

“For having an outdoorsy, fun atmosphere, you’d probably want to have some faceted glass dome, with a park, so you can walk around without a suit,” Musk told the magazine. “Eventually if you terraform the planet, then you can walk around without a suit. But for say, the next 100-plus years, you’ll have to have a giant pressurized glass dome.”

China’s Greater Bay Area still has hurdles to clear if it wants to be a tech challenger to Silicon Valley

Posted by in categories: education, engineering, policy

However, a shortage of hi-tech research capacity in the region is turning into a hindrance, according to analysts, with most of China’s top-notch science and engineering schools located in the northern and eastern provinces. Although Hong Kong has several universities in the world’s top 100, only a few of them have a science and technology focus.


China’s ‘Greater Bay Area’ plan aims to erase barriers between cities in the region in terms of policy, financing, logistics and talent.

Researchers develop new therapeutic approach to treating osteoarthritis

Posted by in categories: biotech/medical, engineering

Researchers from Texas A&M University, led by Dr. Akhilesh K. Gaharwar, have developed a new way to deliver treatment for cartilage regeneration.

Gaharwar, assistant professor in the Department of Biomedical Engineering at Texas A&M, said the nanoclay-based platform for sustained and prolonged delivery of protein therapeutics has the potential to impact treating osteoarthritis, a degenerative disease that affects nearly 27 million Americans and is caused by breakdown of cartilage that can lead to damage of the underlying bone.

As America’s population ages, the number of osteoarthritis incidences is likely to increase. One of the greatest challenges with treating osteoarthritis and subsequent joint damage is repairing the damaged tissue, especially as cartilage tissue is difficult to regenerate.
