Spurious switching points in traded stock dynamics

Physicists have rebuffed the existence of power laws governing the dynamics of traded stock volatility, volume and intertrade times at times of stock price extrema. They did this by demonstrating that what appeared as "switching ...

Superconducting strip could become an ultra-low-voltage sensor

Researchers studying a superconducting strip observed an intermittent motion of magnetic flux which carries vortices inside the regularly spaced weak conducting regions carved into the superconducting material. These vortices ...

Quantum information motion control is now improved

Physicists have recently devised a new method for handling the effect of the interplay between vibrations and electrons on electronic transport. Their paper is about to be published in the European Physical Journal B. This ...

Coalescence-fragmentation cycles based on human conflict

In 1960, Lewis Fry Richardson famously observed that the severity of a wartime event is described by a simple power law distribution that scales according to the size of the conflict. Statisticians have since proposed various ...

Testing particle scattering and reflection in graphene

Humanity stands on the verge of two major revolutions: the boom in 2-dimensional supermaterials like graphene with incredible properties and the introduction of quantum computers with processing power that vastly outstrips ...

How a transparent conductor responds to strain

Liquid crystal displays, touchscreens, and many solar cells rely on thin-film crystalline materials that are both electrically conductive and optically transparent. But the material most widely used in these applications, ...

How a molecular motor moves in a network

A new study determines the efficiency of a single-molecule heat engine by considering a series of ratchets that transfer energy along a network.

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 ...
