Study examines how many scientists a region needs to achieve dominance in a field

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, ...

Dynamical fractal discovered in clean magnetic crystal

The nature and properties of materials depend strongly on dimension. Imagine how different life in a one-dimensional or two-dimensional world would be from the three dimensions we're commonly accustomed to. With this in mind, ...

Synchronizing chaos through a narrow slice of the spectrum

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 ...

Perturbing the Bernoulli shift map in binary systems

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 ...

Study reveals a broken symmetry in the roughness of elastic interfaces

A large class of problems in non-equilibrium statistical physics deal with driven dynamics of elastic interfaces in random media. Examples include stress-driven propagation of crack fronts in disordered solids, motion of ...

Three-dimensional point clouds provide insight into the structural complexity of forests

Structurally complex forests add to biodiversity, increase forest carbon stocks, and help the forest to adapt to climate change. Forest structure refers to the three-dimensional distribution of trees in a given space, and ...

Study proposes mathematical tool to help understand fractal structure of quark-gluon plasma

Quark-gluon plasma (QGP) is a state of matter existing at extremely temperatures and densities, such as those that occur in collisions of hadrons (protons, neutrons and mesons). Under so-called "normal" conditions, quarks ...

Topological synchronization of chaotic systems

Can we find order in chaos? Physicists have shown, for the first time that chaotic systems can synchronize due to stable structures that emerge from chaotic activity. These structures are known as fractals, shapes with patterns ...
