MIT physicists have captured the first images of individual atoms freely interacting in space. The pictures reveal correlations among the “free-range” particles that until now were predicted but never directly observed. Their findings, appearing today in the journal Physical Review Letters, will help scientists visualize never-before-seen quantum phenomena in real space.
The images were taken using a technique developed by the team that first allows a cloud of atoms to move and interact freely. The researchers then turn on a lattice of light that briefly freezes the atoms in their tracks, and apply finely tuned lasers to quickly illuminate the suspended atoms, creating a picture of their positions before the atoms naturally dissipate.
The physicists applied the technique to visualize clouds of different types of atoms, and snapped a number of imaging firsts. The researchers directly observed atoms known as “bosons,” which bunched up in a quantum phenomenon to form a wave. They also captured atoms known as “fermions” in the act of pairing up in free space — a key mechanism that enables superconductivity.
The notion that the quantum realm somehow sits sealed off from the relativistic domain has captured popular imagination for decades. Perhaps this separation is comforting in a way, because it assigns neat boundaries to a notoriously complex theoretical landscape. Yet, a careful look at both cutting-edge research and historical development suggests that no such invisible barrier actually exists. Early quantum pioneers such as Planck (1901) and Heisenberg (1925) laid foundations that seemed confined to the minuscule domain of atoms and subatomic particles. Before long, Einstein (1916) showed us that gravity and motion operate in ways that defy purely Newtonian conceptions, especially at cosmic scales. Despite the apparent chasm between the quantum and relativistic descriptions, threads of continuity run deeper than we once imagined. The famous energy discretization proposed by Planck was intended to solve classical paradoxes at microscopic scales, but the fundamental constants he unveiled remain essential at any size, linking the behavior of infinitesimal systems to grand cosmic events.
Modern experiments push this continuity further into the mainstream conversation. Quantum coherences documented in biological processes illuminate the reality that phenomena once labeled “strictly quantum” can permeate living systems in everyday environments (Engel et al., 2007). Photosynthesizing cells exploit wave-like energy flows, migratory birds appear to navigate using subtle quantum effects, and intriguing evidence suggests that neuronal microtubules might process information at scales once deemed too large for quantum behavior (Hameroff, 1998). If relativity reliably predicts how massive objects curve spacetime, and quantum theory demonstrates how particles and fields manifest as discrete excitations, then the missing piece in unifying these perspectives may hinge on the realization that neither domain is airtight. We stand on a continuum of phenomena, from photosynthetic molecules absorbing photons to astrophysical bodies warping spacetime.
What can the largest geomagnetic storm in decades teach scientists about extreme solar activity and how to prepare for it? This is what a recent study publ | Space
A study led by Paolo Padoan, ICREA research professor at the Institute of Cosmos Sciences of the University of Barcelona (ICCUB), is challenging the understanding of planetary disk formation around young stars.
The paper, published in Nature Astronomy, reveals that the environment plays a crucial role in determining the size and lifetime of these planetary disks, which are the sites of planet formation.
When a star forms, it is surrounded by a spinning disk of gas and dust. Over time, this material eventually forms the planets. Traditionally, scientists believed that once a disk forms, it simply loses too much over time as it feeds the star and the growing planets.
A new study shows that planets bigger than Earth and smaller than Neptune are common outside the Solar System.
An international team including astronomers from the Center for Astrophysics | Harvard & Smithsonian (CfA) has announced the discovery of a planet about twice the size of Earth orbiting its star farther out than Saturn is to the sun.
These results are another example of how planetary systems can be different from our solar system.
Gravity or gravitational force is the result of a computational process within the universe.
A new study shows that the human brain organizes action-outcome associations in cognitive maps, much like how it maps physical space for navigation.
Modern ideas about reality sometimes sound like a wild story. The notion that everything around us might be bits and bytes is easy to brush aside, yet it continues to intrigue many curious minds.
This perspective has led some researchers to wonder if physical forces might be signals of an underlying information system.
According to physicist Melvin M. Vopson of the University of Portsmouth, certain features of gravity may hint at information contained in a universal computational code.
