Searching for scalar dark matter using compact mechanical resonators
Researchers at University of Delaware, University of Arizona and Haverford College have recently introduced the idea of searching for scalar dark matter using compact acoustic resonators. Their paper, published in Physical Review Letters, theoretically demonstrates...
Detecting individual nuclear spins with single rare-earth ions hosted in crystals
Rare-earth minerals are a class of materials with similar properties that are currently used to build a variety of devices, including LEDs, rechargeable batteries, magnets, lasers, and much more. These materials' electron spins can be hosted in crystals, creating...
A system for robust and efficient wireless power transfer
Current methods for charging electronic devices via wireless technology only work if the overall system parameters are set up to match a specific transfer distance. As a result, these methods are limited to stationary power transfer applications, which means that a...
A new technique for the radiative cooling of spin ensembles
Researchers at CEA/CNRS/Université Paris Saclay, University College London and ETH Zurich have recently devised a new method to control the temperature of a spin ensemble by increasing electron spin polarization above its thermal equilibrium value. Their research,...
The observation of photon-assisted tunneling signatures in Majorana wires
Researchers at the University of Copenhagen and Microsoft Quantum Lab Copenhagen have recently carried out a study investigating the potential of Majorana zero modes, zero-energy quasiparticle states that can be found in superconductive hybrid nanowires, as a means of...
Measuring the charge radii of exotic copper isotopes
Researchers at Instituut voor Kern- en Stralingsfysica in Belgium and The University of Manchester, in collaboration with other institutes worldwide, have recently carried out a study aimed at measuring the size of the nucleus (i.e., nuclear charge radius) in...
A new technique for the 3-D printing multimaterial devices
Three-dimensional printing techniques could potentially be used to fabricate a variety of objects with complex geometries, including electronic components. Most 3-D printing approaches developed so far, however, have merely proved effective for producing...
Imaging nematic transitions in iron pnictide superconductors
Researchers at Stanford University have recently carried out an in-depth study of nematic transitions in iron pnictide superconductors. Their paper, published in Nature Physics, presents new imaging data of these transitions collected using a microscope they invented,...
Quantum autoencoders to denoise quantum measurements
Many research groups worldwide are currently trying to develop instruments to collect high-precision measurements, such as atomic clocks or gravimeters. Some of these researchers have tried to achieve this using entangled quantum states, which have a higher...
