Nonlinearity is the driving force for numerous important effects in nature typically showing transitions between different regimes, regular, chaotic or catastrophic behavior. Localized nonlinear modes ...

An international team has pioneered a "motion-picture" method for measuring the precession rate of the Milky Way's disk warp. Using a sample of Cepheid variable stars of different ages, this method ...

A research team led by Dr. HUANG Yang from the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC) pioneered the "motion picture" method for measuring the precession rate of ...

Since its discovery 1, the ultrafast demagnetization and precession of the magnetization induced by femtosecond laser pulses has received intensive attention 2,3,4,5,6,7,8,9,10,11,12,13,14. How fast ...

This is where things get interesting, but let’s quickly recap a few things first. Considering ourselves stationary, we can say that we have a blanket of stars and sky above us; let’s call it the ...

Researchers from Skoltech, the University of Warsaw, and the University of Iceland have demonstrated that by optical means it is possible to excite and stir an exciton-polariton condensate, which ...
