PROVIDENCE, R.I. [Brown University] — New research by physicists from Brown University puts the profound strangeness of quantum mechanics in a nutshell — or, more accurately, in a helium bubble.

Photoelectrons excited by extreme ultraviolet or x-ray photons in the presence of a strong laser field generally suffer a spread of their energies due to the absorption and emission of laser photons.

Electron holography is based on the fundamental principles of holography, which involves the recording and reconstruction of wavefronts. In holography, a hologram is created by capturing the ...

(a) Ordinary electrons without wave shaping have a uniform wave pattern when they travel. In simulations, the electrons collide with the atoms in graphene (red spheres represent graphene atoms and ...

In the world of quantum mechanics, particles can behave like waves. This wave-like nature is crucial for understanding quantum tunnelling. Imagine a tiny particle, like an electron, approaching a hill ...

Sung to the abbess’s lines in “Maria” from The Sound of Music: “How do you catch a wave like Maria? How do you grab a cloud and pin it down? Oh, how do you solve a particle like Maria? How do you hold ...

So far, the team has measured several effects, including wave steepening, shock fronts and solitary wave fission thanks to the chip. While these nonlinear behaviours had been predicted in superfluids, ...

Scientists led by Nanyang Technological University, Singapore (NTU Singapore) have developed and simulated a new energy-efficient way to generate highly focused and finely controlled X-rays that are ...
