Photochemistry is confirmed on an exoplanet

Posted by in categories: chemistry, particle physics, space

The latest data improves our understanding of how clouds in “hot Jupiter” exoplanets like this might appear up close. They are likely to be broken up, rather than a single, uniform blanket over the planet.

Photochemistry is the result of light triggering chemical reactions. This process is fundamental to life on Earth: it makes ozone, for example, which protects us from harsh ultraviolet (UV) rays.

New observations of WASP-39 b, a Jupiter-sized planet orbiting a Sun-like star found 700 light years away, confirm the presence of a never-before-seen molecule in the atmosphere – sulfur dioxide – among other details.

Researchers are building robots that can build themselves

Posted by in categories: particle physics, robotics/AI

Researchers at MIT’s Center for Bits and Atoms are working on an ambitious project, designing robots that effectively self-assemble. The team admits that the goal of an autonomous self-building robot is still “years away,” but the work has thus far demonstrated positive results.

At the system’s center are voxels (a term borrowed from computer graphics), which carry power and data that can be shared between pieces. The pieces form the foundation of the robot, grabbing and attaching additional voxels before moving across the grid for further assembly.

Evidence of Higgs boson contributions to the production of Z boson pairs at high energies

Posted by in categories: particle physics, quantum physics

The Higgs boson, the fundamental subatomic particle associated with the Higgs field, was first discovered in 2012 as part of the ATLAS and CMS experiments, both of which analyze data collected at CERN’s Large Hadron Collider (LHC), the most powerful particle accelerator in existence. Since the discovery of the Higgs boson, research teams worldwide have been trying to better understand this unique particle’s properties and characteristics.

The CMS Collaboration, the large group of researchers involved in the CMS experiment, has recently obtained an updated measurement of the width of the Higgs boson, while also gathering the first evidence of its off-shell contributions to the production of Z boson pairs. Their findings, published in Nature Physics, are consistent with predictions.

“The quantum theoretical description of fundamental particles is probabilistic in nature, and if you consider all the different states of a collection of particles, their probabilities must always add up to 1 regardless of whether you look at this collection now or sometime later,” Ulascan Sarica, researcher for the CMS Collaboration, told “When analyzed mathematically, this simple statement imposes restrictions, the so-called unitarity bounds, on the probabilities of particle interactions at high energies.”

Bulk localized transport states in infinite and finite quasicrystals via magnetic aperiodicity

Posted by in categories: computing, particle physics

Infinite hard drive for computers essentially :3.

Topological edge states can form when a charged particle confined to a crystalline lattice interacts with a magnetic field. These edge states are localized to the boundary and can support transport along the edge even with an insulating bulk. Here, the authors show that a different state that supports transport in the bulk can emerge when the charged particle is on a quasicrystalline lattice. Utilizing a recently developed spectral computation technique, they show that these new bulk localized transport (BLT) states survive in the infinite-size limit.

As Never Seen Before: NASA’s Webb Reveals an Exoplanet Unlike Any in Our Solar System

Posted by in categories: chemistry, food, particle physics, space

Observations of Exoplanet WASP-39b show fingerprints of atoms and molecules, as well as signs of active chemistry and clouds.

WASP-39 b is a planet unlike any in our solar system – a Saturn.

Saturn is the sixth planet from the sun and has the second-largest mass in the Solar System. It has a much lower density than Earth but has a much greater volume. Saturn’s name comes from the Roman god of wealth and agriculture.

BREAKING: Large Hadron Collider Finds Three Never-Before-Seen Particles

Posted by in categories: cosmology, particle physics

Physicists say they’ve found evidence in data from Europe’s Large Hadron Collider for three never-before-seen combinations of quarks, just as the world’s largest particle-smasher is beginning a new round of high-energy experiments.

The three exotic types of particles – which include two four-quark combinations, known as tetraquarks, plus a five-quark unit called a pentaquark – are totally consistent with the Standard Model, the decades-old theory that describes the structure of atoms.

In contrast, scientists hope that the LHC’s current run will turn up evidence of physics that goes beyond the Standard Model to explain the nature of mysterious phenomena such as dark matter. Such evidence could point to new arrays of subatomic particles, or even extra dimensions in our Universe.

Scientists Have Just Announced That They Found A Portal To The Fifth Dimension

Dark matter has long since been an enigma to scientists and astronomers.
Although it takes up most of our universe, scientists have yet to fully unravel.

Scientists are rooted in this idea simply because dark matter takes up most.

Two Paths to a Magnetic Gradiometer

Posted by in categories: particle physics, quantum physics

From the slivers of natural magnetite used as the earliest magnetic compasses to today’s cryogenically cooled superconducting quantum interference devices, researchers have employed many diverse means to measure magnetic fields. Now Robert Cooper at George Mason University, Virginia, and colleagues have added two more [1]. Their instruments, which are variations on a high-precision instrument called an optically pumped atomic magnetometer, are the first demonstrations of “intrinsic radio-frequency gradiometers.” These devices are especially suited to measure weak, local radio-frequency sources while excluding background fields.

At the heart of an optically pumped atomic magnetometer lies a gas of alkali atoms whose spins are aligned by a circularly polarized laser—the optical pump. The presence of an external magnetic field perturbs the spin axis of these atoms, showing up as a change in the polarization direction of the probe beam—a second, linearly polarized laser that is also transmitted through the gas.

In the devices devised by Cooper and his colleagues, the probe beam makes multiple passes through the alkali gas, maximizing the device’s sensitivity to weak fields. In one setup, a high-power probe beam takes a single M-shaped route through the gas, passing twice through a pair of vapor cells. In the other, a low-power beam traces overlapping V-shaped paths, passing 46 times through a single vapor cell.
