Theoreticians at the MPSD have demonstrated how the coupling between intense lasers, the motion of electrons, and their spin influences the emission of light on the ultrafast timescale. Their work has been published in npj ...
Berkeley engineers have created a new type of semiconductor laser that accomplishes an elusive goal in the field of optics: the ability to maintain a single mode of emitted light while maintaining the ability to scale up ...
A quantum system consisting of a large number of microscopic particles obeys statistical laws at the macroscopic level. In nature, there are two kinds of microscopic quantum particles. One is the boson satisfying the Bose-Einstein ...
Some of the world's most powerful particle accelerators have helped researchers draw new leading limits on the existence of long theorized magnetic monopoles from the collisions of energetic cosmic rays bombarding the Earth's ...
Semiconductor lasers are the most widely used lasers due to their compact size, high efficiency, low cost and wide spectra. But they suffer low output power and low beam quality—two specifications difficult to improve simultaneously. ...
A team of scientists have "velcroed" 2D structures of MoS2 and graphene using a covalent connection for the first time. The 2D-2D structures were used to build robust field effect transistors with controlled electronic communication, ...
Almost 400 years ago, in "The Assayer," Galileo wrote: "Philosophy is written in this grand book, the universe … [But the book] is written in the language of mathematics." He was much more than an astronomer, and this can ...
Working with a quantum material known as a kagome magnet, a team of Boston College physicists and colleagues have directly measured how individual electronic quantum states in the novel material respond to external magnetic ...
Theoretical physicists routinely introduce fictitious particles and fields in their calculations, in view of completing a theory or simply to make it more elegant. A striking example concerns the magnetic monopole imagined ...
Topological charge-entropy scaling relation was proved in the kagome Chern magnet, a kind of magnet predicted to support intrinsic Chern quantum phases, according to a study published on Nature Communications.
