Study gathers evidence of topological superconductivity in the transition metal 4Hb-TaS2
Topological superconductors are a class of superconducting materials characterized by sub-gap zero energy localized modes, known as Majorana boundary states (MBSs). These materials are promising for the development of quantum computing technology.
Study reports the ferroelectric switching of spin-to-charge conversion in germanium telluride
Spintronic devices, a class of architectures that can store or transfer information by leveraging the intrinsic spin of electrons, have been found to be highly promising, both in terms of speed and efficiency. So far, however, the development of these devices has been...
The first unequivocal experimental evidence of a superfluid state in 2D 4He films
Over the past few decades, some physicists worldwide have been trying to use the second layer of 4He films adsorbed on a graphite substrate to study the interplay between superfluid and supersolid phases of matter. Some teams have collected torsional oscillator...
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 finds that the fine structure constant of quantum spin ice is large
Quantum electrodynamics (QED) is the fundamental quantum theory governing the behavior of charged particles and light in vacuum. The strength of the interactions in QED is quantified by the fine structure constant α, which in our universe is both immutable and eternal...
Study unveils the quantum nature of the interaction between photons and free electrons
For several decades, physicists have known that light can be described simultaneously as a wave and a particle. This fascinating 'duality' of light is due to the classical and quantum nature of electromagnetic excitations, the processes through which electromagnetic...
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...
Researchers use the S-matrix bootstrap to examine whether string theory is the only consistent theory of quantum gravity
The S-matrix bootstrap is a numerical method that can be used to determine or constrain the scattering amplitudes of particles in quantum field theory using simple principles. Over the past few decades, some physicists have tried to use this technique to study...
