New conversion surfaces to enhance spacecraft instruments

Posted by in categories: engineering, particle physics, space

Southwest Research Institute has invested in research to enhance the capabilities of spacecraft instruments. Consequently, they have developed more effective conversion surfaces for the detection and analysis of low-energy particles in outer space.

Led by Dr. Jianliang Lin of Mechanical Engineering and Dr. Justyna Sokół of the Space Science Division, the project could potentially change our understanding of space physics and exploration.

Study demonstrates atomic layer deposition route to scalable, electronic-grade van der Waals tellurium thin films

Posted by in categories: engineering, particle physics

A research team, led by Professor Joonki Suh in the Department of Materials Science and Engineering and the Graduate School of Semiconductor Materials and Devices Engineering at UNIST, has made a significant breakthrough in thin film deposition technology. By employing an innovative atomic layer deposition (ALD) process, Professor Seo successfully achieved regular arrangement of tellurium (Te) atoms at low temperatures as low as 50 degrees Celsius.

The ALD method is a cutting-edge thin film process that enables precise stacking of semiconductor materials at the atomic layer level on three-dimensional structures—even at low process temperatures. However, traditional application to next-generation semiconductors requires high processing temperatures above 250 degrees Celsius and additional heat treatment exceeding 450 degrees Celsius.

In this research, the UNIST team applied ALD to monoelemental van der Waals tellurium—a material under extensive investigation for its potential applications in and thermoelectric materials.

“Because like-charged objects in a vacuum are expected to repel regardless of whether the sign of the charge they carry is positive or negative, the expectation is that like-charged particles in solution must also monotonically repel,” the researchers wrote in the paper.

Mapping the best route for a spacecraft traveling beyond the sun’s sphere of influence

Posted by in categories: cosmology, mapping, particle physics

The heliosphere—made of solar wind, solar transients, and the interplanetary magnetic field—acts as our solar system’s personal shield, protecting the planets from galactic cosmic rays. These extremely energetic particles accelerated outwards from events like supernovas and would cause a huge amount of damage if the heliosphere did not mostly absorb them.

A new fullertube molecule is found

Posted by in category: particle physics

For years, C130 fullertubes—molecules made up of 130 carbon atoms—have existed only in theory. Now, leading an international team of scientists, a UdeM doctoral student in physics has successfully shown them in real life—and even managed to capture some in a photograph.

Physicists propose new way to search for dark matter: Small-scale solution could be key to solving large-scale mystery

Posted by in categories: cosmology, particle physics, quantum physics

Ever since its discovery, dark matter has remained invisible to scientists despite the launch of multiple ultra-sensitive particle detector experiments around the world over several decades.

Now, physicists at the Department of Energy’s (DOE) SLAC National Accelerator Laboratory are proposing a new way to look for using quantum devices, which might be naturally tuned to detect what researchers call thermalized dark matter.

Most dark matter experiments hunt for galactic dark matter, which rockets into Earth directly from space, but another kind might have been hanging around Earth for years, said SLAC physicist Rebecca Leane, who was an author of the new study.

A method to compute the Rényi entanglement entropy in auxiliary-field quantum Monte Carlo simulations

Posted by in categories: particle physics, quantum physics

Entanglement is a widely studied quantum physics phenomenon, in which two particles become linked in such a way that the state of one affects the state of another, irrespective of the distance between them. When studying systems comprised of several strongly interacting particles (i.e., many body systems) in two or more dimensions, numerically predicting the amount of information shared between these particles, a measure known as entanglement entropy (EE), becomes highly challenging.
