Researchers at the University of Southampton and the Korea Institute for Advanced Study have recently showed that supersymmetry is anomalous in N=1 superconformal quantum field theories (SCFTs) with an anomalous R symmetry. The anomaly described in their paper,...
Astrophysicists have been searching for dark matter for several decades, but these searches have so far yielded disappointing results. In a recent study, two researchers at Weizmann Institute of Science and the Hebrew University of Jerusalem in Israel have introduced...
In quantum electrodynamics, the choice of gauge (i.e. specific mathematical formalism used to regulate degrees of freedom) can greatly influence the form of light-matter interactions. Interestingly, however, the "gauge invariance" principle implies that all physical...
Helium and water are known to be abundant throughout the universe, particularly in giant planets such as Uranus and Neptune. Although helium is typically unreactive at common atmospheric conditions, past studies have found that it can sometimes react with other...
In current quantum field theory, causality is typically defined by the vanishing of field commutators for spacelike separations. Two researchers at the University of Massachusetts and Universidade Federal Rural in Rio de Janeiro have recently carried out a study...
A team of researchers at Laroche Laboratory, Université Paris Diderot and Université de Lyon has recently collected the first measurements of the resonance frequencies of a stable torus of fluid. The method they used to collect these observations, outlined in a paper...
In a recent study, a team of researchers has presented new direct-detection constraints on eV-to-GeV dark matter interacting with electrons, using a new prototype detector developed as part of the Sub-Electron-Noise Skipper-CCD Experimental Instrument (SENSEI)...
Although several past studies have investigated the formation of crystals from identical particles, the conditions under which non-uniform particles crystallize and the crystals resulting from this process are still poorly understood. In a recent study published in...
Hybrid organic or inorganic halide perovskites are a unique class of solar cell materials that break some of the material design rules that have been in place for over 30 years. For instance, they can achieve an extraordinarily high performance, despite being rich in...
Some species of Euglenids, a diversified family of aquatic unicellular organisms, can perform large-amplitude, elegantly coordinated body deformations. Although this behavior has been known for centuries, its function is still highly debated.
