Physicists take molecules to a new ultracold limit to create a Bose-Einstein condensate

Posted by in categories: particle physics, quantum physics

There’s a hot new BEC in town that has nothing to do with bacon, egg, and cheese. You won’t find it at your local bodega, but in the coldest place in New York: the lab of Columbia physicist Sebastian Will, whose experimental group specializes in pushing atoms and molecules to temperatures just fractions of a degree above absolute zero.

Writing in Nature (“Observation of Bose-Einstein Condensation of Dipolar Molecules”), the Will lab, supported by theoretical collaborator Tijs Karman at Radboud University in the Netherlands, has successfully created a unique quantum state of matter called a Bose-Einstein Condensate (BEC) out of molecules.

Their BEC, cooled to just five nanoKelvin, or about-459.66 F, and stable for a strikingly long two seconds, is made from sodium-cesium molecules. Like water molecules, these molecules are polar, meaning they carry both a positive and a negative charge. The imbalanced distribution of electric charge facilitates the long-range interactions that make for the most interesting physics, noted Will.

Exploring the Unknown: A Unique Quantum State of Matter Emerges at Columbia

Physicists at Columbia University have taken molecules to a new ultracold limit and created a state of matter where quantum mechanics reigns.

Astrophotographer captures planetary parade with the moon in stunning photo

Posted by in category: cosmology

The much-hyped planetary alignment of June may not have been the jaw-dropping naked-eye spectacle some made it out to be, but it still made for some stunning astrophotography.

Josh Dury of Somerset, England caught the planetary parade on June 1, 2024, from atop Crooks Peak, a popular and historic outcropping of rock in the Mendip Hills.

Our universe may have an anti-universe twin on the other side of the Big Bang, say physicists

Posted by in categories: cosmology, particle physics

It’s possible that our universe is the antimatter counterpart of an antimatter universe that existed earlier in time than the Big Bang. So claim physicists in Canada, who have devised a new cosmological model positing the existence of a “antiuniverse” which, paired to our own, preserves a fundamental rule of physics called CPT symmetry. Though many details in their theory still need to be worked out, the researchers claim that it naturally explains the existence of dark matter.

According to standard cosmological models, the universe—which consists of space, time, and mass/energy—exploded into being about 14 billion years ago. Since then, it has expanded and cooled, causing subatomic particles, atoms, stars, and planets to gradually form.

China opens world’s biggest solar farm that spreads over 200,000 acres

Posted by in categories: solar power, sustainability

China has just connected what it believes to be the world’s biggest solar power plant to the grid in northwestern Xinjiang. The plant covers an area of 200,000 acres and is reported to have an output of 6.09 billion kWh annually.

The new plant is in the deserts near the region’s capital Ürümqi. The site came online this Monday (June 3) and is being run by the Chinese state-owned Power Construction Corporation, according to Reuters.

Revolutionary thin film can add night vision to normal glasses

Posted by in category: entertainment

The new ultra-light night vision filters which weigh less than a gram almost resemble those seen in the movies. These glasses allow users to catch a glimpse of the visible and infrared spectrum. They also help in allowing the user to drive safely in the dark.

As of now, traditional night vision technology is in use. It required infrared photons to pass through a lens. Then it would meet a photocathode that would help in transforming these photons into electrons.

These electrons travel through a phosphor screen and are reconverted back to photons. These produce an intensely visible image which the human eye can see. In order to prevent thermal noise from being intensified these elements need cryogenic cooling.

MIT-backed first-of-its-kind headband offers drug-free sleep solution

Posted by in categories: biotech/medical, mobile phones, neuroscience, wearables

The Elemind headband is a soft, lightweight, and flexible wearable designed to be worn throughout the night, regardless of one’s sleeping position. It can collect information using brainwaves and pairs with a smartphone, where users can find details about their sleep patterns.

Where the headband is effective is its ability to use neuromodulation to impact the brainwaves, directing them from wakeful patterns to those of deeper sleep. “Elemind works like noise-cancellation for the brain. You can switch off the world, switch off the stress, and go to sleep faster,” explained Meredith Perry, the CEO and co-founder of Elemind.
