Black hole thermodynamics
In the 1800s scientists studying things like heat and the behavior of low density gases developed a theory known as thermodynamics. As the name suggests, this theory describes the dynamic behavior of heat ...
Particles near absolute zero do not break the laws of physics after all
In theory, the laws of physics are absolute. However, when it comes to the laws of thermodynamics—the science that studies how heat and temperature relate to energy—there are times where they no longer seem to apply. ...
Physics team suggests possible way to make quantum cryptography available in handheld machines
Novel topological crystalline insulator shows mass appeal
Disrupting the symmetrical structure of a solid-state topological crystalline insulator creates mass in previously mass-less electrons and imparts an unexpected level of control in this nascent class of materials, an international ...
Quantum engines must break down
Our present understanding of thermodynamics is fundamentally incorrect if applied to small systems and needs to be modified, according to new research from University College London (UCL) and the University of Gdańsk. The ...
Researchers 'light' magnetic fire and analyse how energy propagates
The propagation of the so-called 'magnetic fire' in certain systems seems to be "the only combustion process ruled by quantum laws known in the nature", points out Javier Tejada, Professor of Condensed Matter ...
Engineers using quantum nature of light to boost Internet security
Michael Vasilyev's goals in his research are simply stated: increase by tenfold the amount of information that can be securely transmitted via the Internet and the distance over which that data can be transmitted.
Physicists propose measure of macroscopicity; Schrodinger's cat scores a 57
Movement of pyrrole molecules defy 'classical' physics
(Phys.org) —New research shows that movement of the ring-like molecule pyrrole over a metal surface runs counter to the centuries-old laws of 'classical' physics that govern our everyday world.
Scientists propose creating Maxwell's demon with two quantum dots
Mathematical breakthrough sets out rules for more effective teleportation
For the last ten years, theoretical physicists have shown that the intense connections generated between particles as established in the quantum law of 'entanglement' may hold the key to eventual teleportation of quantum ...
Scientists design, control movements of molecular motor
(Phys.org)—An international team of scientists has taken the next step in creating nanoscale machines by designing a multi-component molecular motor that can be moved clockwise and counterclockwise.
First noiseless single photon amplifier
Research physicists have demonstrated the first device capable of amplifying the information in a single particle of light without adding noise.
Team maps the nuclear landscape
An Oak Ridge National Laboratory and University of Tennessee team has used the Department of Energy's Jaguar supercomputer to calculate the number of isotopes allowed by the laws of physics.
