A strategy to control the spin polarization of electrons using helium
Spintronics, also known as spin electronics, is a research field that explores how the intrinsic spin of electrons and its magnetic moment can be exploited by devices. Spintronic devices are promising for a wide range of applications, particularly for efficiently...
Study demonstrates the potential of a quantum computer comprised of a small processor and a storage unit
Quantum computing systems, computer systems that are based on the key principles of quantum theory, could significantly outperform conventional computing systems, both in terms of speed and performance. Over the past decade or so, many physicists worldwide have thus...
A new theory to test hypotheses and methods for exoplanet detection
Countless astrophysicists and astronomers are actively searching for unobserved celestial bodies in the universe, as detecting these bodies could improve our understanding of space and help to address unanswered astrophysical questions. Among these elusive objects are...
Study demonstrates the robust storage of qubits in ultracold polar molecules
Molecules have a very intricate and rich structure, which allows them to rotate and vibrate freely. As a result, they have an almost limitless space in which computer scientists could encode quantum information. In addition to their vast internal space, molecules are...
A strategy to control phase selectivity in templated zeolite synthesis
Zeolites, groups of minerals comprising of hydrated aluminosilicates, are known to be highly promising materials for a number of applications. For instance, they can be used as catalysts, cation exchangers and molecular sieves.
Study unveils the minimum temperature for droplets levitating from smooth surfaces
The Leidenfrost effect is a well-known physical phenomenon first discovered in 1756. It occurs when a liquid is in the proximity of a surface that is significantly warmer than its boiling point. This produces an insulating vapor layer that prevents the liquid from...
Researchers realize a spin field-effect transistor at room temperature
A crucial goal of spintronics research is to coherently manipulate electron spins at room temperature using electrical current. This is particularly valuable as it would enable the development of numerous devices, including spin field-effect transistors.
The first experimental realization of a dissipative time crystal
A time crystal is a unique and exotic phase of matter first predicted by the American physicist Frank Wilczek in 2012. Time crystals are temporal analogs of more conventional space crystals, as both are based on structures characterized by repeating patterns.
Physicists use a new absorbing-state model to investigate random close packing
Sphere packing, a mathematical problem in which non-overlapping spheres are arranged within a given space, has been widely investigated in the past. It has been proven that the densest possible packing is a face-centered cubic (FCC) crystal with a space-filling...
