Germany, India, Mexico, and Spain. As multiparty democracies, these countries present a more complex picture of what brings people together—or divides them. Using social media data, a group of researchers proposes a novel ...
For yet another year, the world's conference on climate change—COP27—concluded with few agreements and a clear division between North and South.
Microresonators based frequency combs, microcombs, have attracted huge interest in the last decades for their revolutionary performance of compact size, flexible comb spacing, and broad bandwidth. Wide applications of microcombs ...
We can frequently find in our daily lives a localized wave structure that maintains its shape upon propagation—picture a smoke ring flying in the air. Similar stable structures have been studied in various research fields ...
Particles of light—photons—that are forced to interact with each other through specially structured glass demonstrate behavior evocative of the "fractional quantum Hall effect," a phenomenon that garnered the 1998 Nobel ...
To find out how many scientists a region needs to become a leader in a discipline, researchers at Complexity Science Hub tracked millions of scientists moving across the globe. Their result: there is no critical mass of scientists, ...
Over the past decades, researchers have demonstrated conventional solitons, stretched pulses, self-similar pulses, and dissipative solitons by managing the dispersion and nonlinearity of fiber lasers. However, new types of ...
Researchers have developed a very bright light source that covers seven optical octaves—from ultraviolet (UV) to terahertz (THz) wavelengths. The tabletop coherent source features a spectral brightness up to five orders ...
The abstract notion that the whole can be found in each part of something has for long fascinated thinkers engaged in all walks of philosophy and experimental science, from Immanuel Kant on the essence of time to David Bohm ...
Is it possible for a deterministic system to be unpredictable? Although counter-intuitive, the answer is yes. Such systems are called "chaotic systems," which are characterized by sensitive dependence on initial conditions ...
