New physical behavior, such as Mott insulating behavior, unconventional superconductivity and quantum spin liquid behavior, occurs when electrons inside a material interact with each other. When electrons are confined to lower dimensions such as 2-D planes, these...
The electronic Barnett effect, first observed by Samuel Barnett in 1915, is the magnetization of an uncharged body as it is spun on its long axis. This is caused by a coupling between the angular momentum of the electronic spins and the rotation of the rod.
For the Kerker effect to occur, particles need to have electric and magnetic polarizabilities of the same strength. This, however, is very challenging to achieve, as magnetic optical resonances in small particles are relatively weak. Researchers at Ioffe Institute, in...
A few years ago, the LIGO/Virgo collaboration detected gravitational waves arising from a binary black hole merger using the two detectors of the Laser Interferometer Gravitational-Wave Observatory (LIGO). This eventually led to the observation of black holes with...
Two researchers at Université de Sherbrooke, in Canada, have recently developed and trained neural belief-propagation (BP) decoders for quantum low-density parity-check (LDPC) codes. Their study, outlined in a paper published in Physical Review Letters, suggests that...
Researchers at Max Planck Institute for the Science of Light and Friedrich Alexander University in Erlangen, Germany have recently demonstrated that a molecule can be turned into a coherent two-level quantum system. In their study, published in Nature Physics, they...
Researchers at Hebei University in China and Hakkaido University in Japan have recently used a selective light absorber to construct a photothermal system that can generate temperatures up to 288°C under weak solar irradiation (1 kW m-2). This system, presented in...
Recent polarized inelastric neutron scattering experiments have identified the amplitude (i.e. Higgs) mode in C9H18N2CuBr4, a 2-D, near-quantum-critical spin ladder compound that exhibits a weak easy-axis exchange anisotropy. Inspired by these findings, researchers at...
Researchers at the University of Florence and Istituto dei Sistemi Complessi, in Italy, have recently proved that the invasiveness of quantum measurements might not always be detrimental. In a study published in Physical Review Letters, they showed that this invasive...
Our current understanding of physics suggests that there are two main types of matter in the universe known as dark and baryonic matter. Dark matter is made up of material that scientists cannot directly observe, as it does not emit light or energy. On the other hand,...
