Scientists have used ultracold atoms to successfully demonstrate a novel method of particle acceleration that could unlock a ...

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

Fiber optic gyroscope (FOG) plays a critical role in aerospace, marine transportation, geological exploration, and other fields because of its advantages of low cost and broad development prospects.

This paper proposes a novel model to attain high birefringence and low loss in a slotted core-based photonic crystal fiber (PCF) structure in THz regime. The performance of the proposed PCF has been ...

With this latest breakthrough, India’s quantum communications can now work in real-world combat zones, deserts, hillsides, ...

An attosecond—or 0.000000000000000001 second—is no time at all for a person. That is not so for electrons, atoms and ...

Optimizing the geometric parameters of polymer nanoantenna arrays significantly improves the performance of optical ...

Water frozen in the depths of space has long been considered a shapeless, frozen fog. For decades, scientists believed it ...

The project also benefits from strong industry backing, with six partners contributing technical expertise and in-kind ...

In this paper, a fifth-order variable-coefficient nonlinear Schrödinger equation is investigated, which describes the propagation of the attosecond pulses in an optical fiber. Via the Hirota’s method ...

Scientists have captured the moment a laser "comes to life"—and what they found challenges long-held beliefs. Using a special ...

An invisible force has long eluded detection within the halls of the world’s most famous particle accelerator—until now.
