Scientists have discovered a revolutionary new method for creating quantum states by twisting materials at the M-point, revealing exotic phenomena previously out of reach. This new direction ...

Caltech scientists have found a fast and efficient way to add up large numbers of Feynman diagrams, the simple drawings ...

Here, to avoid these problems, we propose a novel absolutely single-polarization PBG fiber structure with an elliptical-hole lattice core. A PBG fiber with a single-polarization bandwidth of 420 nm is ...

A detailed model for semiconductor linear optical amplifiers (LOAs) with gain clamping by a vertical laser field is presented, which accounts the carrier and photon density distribution in the ...

Excitons—bound pairs of electrons and an electron hole—are quasiparticles that can arise in solids. While so-called "bright" ...

Quantum sensors have become important tools in low-energy particle physics. Michael Doser explores opportunities to exploit ...
