Researchers demonstrate a superconductor previously thought impossible

Superconductivity is a phenomenon in which an electric circuit loses its resistance and becomes extremely efficient under certain conditions. There are different ways in which this can happen, which were thought to be incompatible. ...

Shedding light on moiré excitons: A first-principles perspective

Moiré superlattices that are located within van der Waals (vdW) heterostructures can trap long-lived interlayer excitons to form ordered quantum dot arrays, paving the way for unprecedented optoelectronic and quantum information ...

A phonon laser: Coherent vibrations from a self-breathing resonator

Lasing—the emission of a collimated light beam of light with a well-defined wavelength (color) and phase—results from a self-organization process, in which a collection of emission centers synchronizes itself to produce identical ...

Quantum simulation of quantum crystals

The quantum properties underlying crystal formation can be replicated and investigated with the help of ultracold atoms. A team led by Dr. Axel U. J. Lode from the University of Freiburg's Institute of Physics has now described ...

Theoretical study shows that matter tends to be ordered at low temperatures

Classical phase transitions are governed by temperature. One of the most familiar examples is the phase transitions of water from solid to liquid to gas. However, other parameters govern phase transitions when temperatures ...

Albert Einstein the mediocre: Why the h-index is a bogus measure of academic impact

Earlier this year, French physician and microbiologist Didier Raoult generated a media uproar over his controversial promotion of hydroxychloroquine to treat COVID-19. The researcher has long pointed to his growing list of ...

Tabletop quantum experiment could detect gravitational waves

Predicted by Einstein's general theory of relativity, gravitational waves are ripples in space-time generated by certain movements of massive objects. They are important to study because they allow us to detect events in ...

A Metal-like quantum gas: A pathbreaking platform for quantum simulation

Electronic properties of condensed matter are often determined by an intricate competition between kinetic energy that aims to overlap and delocalize electronic wave functions across the crystal lattice, and localizing electron-electron ...

World's fastest Bose-Einstein condensate created

Researchers have created a Bose-Einstein condensate with record speed, creating the fascinating phase of matter in about 100 femtoseconds. To get an idea of how quick that is, hundred femtoseconds compared to one second is ...
