Why Einstein must be wrong: In search of the theory of gravity

Einstein's theory of gravity—general relativity—has been very successful for more than a century. However, it has theoretical shortcomings. This is not surprising: the theory predicts its own failure at spacetime singularities ...

Using quantum materials as catalysts for fertilizer synthesis

Synthetic fertilizers, one the most important developments in modern agriculture, have enabled many countries to secure a stable food supply. Among them, organic ureas (or organoureas) have become prominent sources of nitrogen ...

A quantum leap in mechanical oscillator technology

Over the past decade, scientists have made tremendous progress in generating quantum phenomena in mechanical systems. What seemed impossible only fifteen years ago has now become a reality, as researchers successfully create ...

Uncovering spin ladders in real chemical compounds

When fabricated in one or two dimensions, systems of particles whose quantum spins interact with each other can display some unique quantum properties. Through new research published in The European Physical Journal B, Asif ...
