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...
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...
The observation of correlated states and superconductivity in twisted trilayer graphene
When two layers of graphene or of other two-dimensional (2D) materials are stacked on top of each other with a small angle misalignment, the crystal lattices produced by each layer are spatially 'out of synch'. This results in a unique structural pattern known as...
A strategy that could enable control over the coherence properties of light emitted by lasers
Over the past few years, physicists and engineers worldwide have developed a growing number of advanced optical technologies and photonic devices, which can be used to emit, detect or manipulate light. The ability to easily control the coherence properties of emitted...
Researchers observe interband collective excitations in twisted bilayer graphene
Twisted bilayer graphene is a carbon-based, two-dimensional (2D) material comprising two graphene layers. Although many scientists have recently started exploring its potential for superconductivity and magnetism, so far, there have been very few optical studies...
Researchers observe translation symmetry breaking in twisted bilayer graphene
Magic-angle twisted bilayer graphene is a material made of two sheets of graphene placed on top of each other, with one sheet twisted at precisely 1.05 degrees with respect to the other. This material has been found to be a very promising platform for studying...
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...
