Quantum leap for speed limit bounds

Nature's speed limits aren't posted on road signs, but Rice University physicists have discovered a new way to deduce them that is better—infinitely better, in some cases—than previous methods.

Mathematician suggests a scheme for solving telegraph equations

A mathematician from RUDN University suggested a stable difference scheme for solving inverse problems for elliptic-telegraph and differential equations that are used to describe biological, physical, and sociological processes. ...

Oscillating quasiparticles: the cycle of decay and rebirth

Decay is relentless in the macroscopic world: Broken objects do not fit themselves back together again. However, other laws are valid in the quantum world: New research shows that so-called quasiparticles can decay and reorganize ...

Mathematically ranking ranking methods

In a world where everything from placement in a Google search result to World Cup eligibility depends on ranking and numerical ratings of some kind, it is becoming increasingly important to analyze the algorithms and techniques ...

Plasma and nanotechnology applications through maths

Plasma is one of the four fundamental states of matter, alongside solid, liquid and gas. Ubiquitous in form, plasma is an ionised gas so energised that electrons have the capacity to break free from their nucleus.
