Crafting organic molecules into a bizarre kind of magnet, physicists from Aalto University and the University of Jyväskylä in Finland have created the perfect space for observing the elusive activity of an electronic state called a triplon.
Where a garden variety magnet is typically best described as having two poles surrounded by a nest of field lines, the curious construct known as a quantum magnet defies such a simple description.
As is the case any time the word 'quantum' appears, you can imagine a landscape where nothing is certain. Like spinning roulette wheels in a dimly lit casino, all states are a maybe until the croupier says"no more bets". Weirder still, numbers and colors on one wheel are entangled with those on other wheels in non-intuitive ways, such that a result of black on one might mean landing on red on another.
With north and south reduced to a flux of probabilities, quantum magnets have properties your fridge magnet lacks, making them handy objects for exploring phenomena that aren't easily spotted in most other environments.Reach into an atomic bag and pluck out an electron. There's an equal chance it will have one of two spins, or flavors of angular momentum. Find an electron with the opposite spin and the two will cancel out.
But what if the two in your initial pairing have the same spin? Instead of canceling, they now build into aAlthough the two electrons in a triplet are often parked in their own distinct atomic orbits, physicists can conveniently group their characteristics together and treat them as a 'sort-of-particle': a

Research group detects a quantum entanglement wave for the first time using real-space measurementsTriplons are tricky little things. Experimentally, they're exceedingly difficult to observe. And even then, researchers usually conduct the tests on macroscopic materials, in which measurements are expressed as an average across the whole sample.

How to prepare your home for summer heat wavesEvery year, an estimated 600 people in the U.S. die in extreme heat waves. Nearly 10,000 are hospitalized and more than 67,000 visit emergency rooms. This year, record-smashing heat waves have swept across the southwestern United States, which has sweltered under temperatures above 100 degrees for weeks. In July, excessive heat warnings were announced for many western U.S. states, Texas and some of Florida.
