MIT Physicists Build a Quantum-Gas Microscope for Fermionic Atoms

A team of physicists has built a microscope that is able to freeze and image 1,000 individual fermionic atoms at once. Fermions are the building blocks of matter, interacting in a multitude of permutations to give rise to the elements of the periodic table. Without fermions, the physical world would not exist. Examples of fermions […]

Whispering Gallery Effect Confines Electrons

A newly published study details how physicists from MIT used a new “whispering gallery” effect to confine electrons in a nanoscale circular cavity in graphene. Researchers have succeeded in creating a new “whispering gallery” effect for electrons in a sheet of graphene — making it possible to precisely control a region that reflects electrons within […]

New Detector Sees Single Electrons

A new tabletop particle detector is able to identify single electrons in a radioactive gas, a big step toward measuring the mass of a neutrino. As the gas decays and gives off electrons, the detector uses a magnet to trap them in a magnetic bottle. A radio antenna then picks up very weak signals emitted […]

Scientists Make Objects Invisible without Metamaterial Cloaking

A team of physicists has managed to make homogenous cylindrical objects completely invisible in the microwave range without relying on metamaterial coatings. The method is based on a new understanding of electromagnetic wave scattering. The scientists studied light scattering from a glass cylinder filled with water. In essence, such an experiment represents a two-dimensional analog […]

New Technique Could Make Atomic Clocks More Accurate

Researchers have developed a new technique that can entangle thousands of atoms with a single photon, opening the door to a new class of entangled states. Physicists from MIT and the University of Belgrade have developed a new technique that can successfully entangle 3,000 atoms using only a single photon. The results, published today in […]

Quantum Experiment Verifies Nonlocal Wavefunction Collapse

Physicists from Griffith University have demonstrated “spooky action at a distance” for the first time with no efficiency loophole by splitting a single photon between two laboratories and experimentally testing if the choice of measurement in one lab really causes a change in the local quantum state in the other lab. An experiment devised in […]

Researchers Discover the Sound of Stars

A chance discovery by a team of physicists has provided experimental evidence that stars may generate sound. The study of fluids in motion – now known as hydrodynamics – goes back to the Egyptians, so it is not often that new discoveries are made. However when examining the interaction of an ultra-intense laser with a […]

Entanglement Can Improve the Performance of Optical Sensors

A new study from MIT demonstrates that entanglement can improve the performance of optical sensors, even when it doesn’t survive light’s interaction with the environment. The extraordinary promise of quantum information processing — solving problems that classical computers can’t, perfectly secure communication — depends on a phenomenon called “entanglement,” in which the physical states of […]

Forbidden Atomic Transitions Driven by an Intensity-Modulated Laser Trap

In a new study, researchers at the University of Michigan detail how they used light to study and control matter with 1,000 times better resolution and precision than previously possible. Physicists at the University of Michigan have demonstrated “ponderomotive spectroscopy,” an advanced form of a technique that was born in the 15th century when Isaac […]

New Image of the Pillars of Creation

A new study from UCLA physicists offers a possible solution to the mystery of the origin of matter in the universe. Most of the laws of nature treat particles and antiparticles equally, but stars and planets are made of particles, or matter, and not antiparticles, or antimatter. That asymmetry, which favors matter to a very […]

Yale Physicists Discover a New Form of Quantum Friction

Physicists at Yale University have observed a new form of quantum friction that could open new avenues in the fields of nonlinear quantum optics and quantum information, where systems with multi-dimensional steady state manifolds can be used as error corrected logical qubits. The researchers have experimentally confined the state of a harmonic oscillator to the […]

Scientists Observe the Transition State in a Chemical Reaction on a Catalyst’s Surface

A newly published study details the process used by an international team of scientists to observe the transition state in a chemical reaction on a catalyst’s surface for the first time. For the first time, an international scientists’ team observed the volatile intermediate stages which appear when carbon monoxide oxidizes on a hot ruthenium surface, […]

Engineers Change Electron Trajectories

In a newly published study, engineers demonstrate a novel approach to substantially modify orbital occupations and symmetries in electronically correlated oxides. How do you make nickel look and behave like copper? A team of scientists at Yale University has done just that by developing a novel technique to artificially alter a material’s atomic properties by […]

Quantum Computer Shows Space Is Not Squeezed

Using partially entangled atoms, a new experiment by UC Berkeley physicists demonstrated more precisely than ever before that space looks the same in all directions. Berkeley — Ever since Einstein proposed his special theory of relativity in 1905, physics and cosmology have been based on the assumption that space looks the same in all directions […]

Physicists Slow Down the Speed of Light Traveling Through Air

By applying a mask to an optical beam to give photons a spatial structure, physicists have demonstrated that spatially structured photons travel slower than the speed of light in free space. Scientists have long known that the speed of light can be slowed slightly as it travels through materials such as water or glass. However, […]

Scientists Peer into Cosmic Magnetic Fields

Using a proton probe to directly image electromagnetic fields, scientists from the Lawrence Livermore National Laboratory present evidence of Weibel-generated magnetic fields that grow in opposing, initially unmagnetized plasma flows from laser-driven laboratory experiments. The generation of cosmic magnetic fields has long intrigued astrophysicists. Since it was first described in 1959, a phenomenon known as […]
