Computing with spins of light

A laser system that generates spinning light particles could lead to the strong kind of computational power needed to solve complex biological problems. The system, which improves on previous ones, is described in the journal ...

Researchers report MRI on the atomic scale

Researchers at QuTech, a collaboration of TU Delft and TNO, have developed a new magnetic quantum sensing technology that can image samples with atomic-scale resolution. It opens the door towards imaging individual molecules, ...

Perpetual predator-prey population cycles

How can predators coexist with their prey over long periods without the predators completely depleting the resource that keeps them alive? Experiments performed over a period of 10 years by researchers from McGill University ...

2-D topological physics from shaking a 1-D wire

Limiting quantum particles to move in one, two, or three dimensions has led to the observation of many striking phenomena. A prime example is the quantization of the Hall conductance measured in 2-D materials in a strong ...

Complex systems

Complex systems is a scientific field which studies the common properties of systems that are considered fundamentally complex. Such systems may exist in nature, society, science and many other fields. It is also called complex systems theory, complexity science, study of complex systems, sciences of complexity, non-equilibrium physics, and historical physics. The key problems of such systems are difficulties with their formal modeling and simulation. From such perspective, in different research contexts complex systems are defined on the base of their different attributes. Since all complex systems have many interconnected components, the science of networks and network theory are always important aspects of the study of complex systems. At present, the consensus related to one universal definition of complex system does not exist yet.
