source:LASER&SOURCESThe 3 petawatt (3 PW) ZEUS laser at the University of Michigan (U-M; Ann Arbor, MI) has been awarded $18.5 million by the National Science Foundation (NSF; Alexandria, VA) to establish it as a federally funded international user facility. ZEUS is expected to begin its first experiments in early 2022.The U.S. built the world’s first petawatt laser in 1996, but hasn’t kept pace with more ambitious systems under construction elsewhere in the world. This includes two 10 PW lasers in Europe and a 5.3 PW laser in China, which also has plans to build a 100 PW laser. While the ...

source:Tech news incn 2012, the physicist Frank Wilczek He put forward a strange theory: according to him, there is a structure made up of a group of particles that move periodically and return to their original state; He baptized this structure, the “time crystal”.This name comes under what is observed in the “classic” crystal. In fact, The structure of a regular crystal will show a repeating pattern in different directions in space. However, in a time crystal, the pattern repeats periodically over time, like an oscillator. The physicist also adds that time crystal It must be distinguished fr...

source:PHYSORGFor years, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have engineered metasurfaces to manipulate light based on its polarization state. That research has contributed to advances in polarization technology—but metasurface technology has proven more powerful than even the researchers themselves realized.Now, researchers have uncovered hidden potential in these metasurfaces and, in a new paper, demonstrated optical devices that manipulate light's polarization state with an unprecedented degree of control.'This research shows ...

source:The West AustralianAustralian Bauxite’s foray into rare earth elements seems to be hitting the mark with latest assay results from exploration drilling at the company’s bauxite project in northern Tasmania showing a significant increase in the extent and thickness of the rare earths enrichment within the bauxite project.New mineralised zones appear to be trending to the northeast, northwest and to the south.The significant anomalous rare earth elements recorded from the DL130 bauxite project west of Launceston is neodymium, which is the main component of super-magnets used in electric v...
