In this paper we study the entanglement dynamics of spin–subband states for an electron in a quasi-one-dimensional Rashba quantum loop, in a strong perpendicular magnetic field, explicitly including the confining potential and the Rashba spin–orbit coupling into the entropy, which is a measure of entanglement, as a function of time.

With more content than any book and better analytical tools than any software, MCAT Physics Connect is a must-have for a MCAT Physics test taker.

Professor Deborah Jin won the William Procter Prize for Scientific Achievement. Now therea s another reason for CU to boast about its science program.

Was Newton right and Einstein wrong? It seems that unzipping the fabric of spacetime and harking back to 19th-century notions of time could lead to a theory of quantum gravity.

Wurzburg physicists are global leaders in the creation of sophisticated nanostructures.

MRSA and other drug-resistant bacteria could face annihilation as low-temperature plasma prototype devices have been developed to offer safe, quick, easy and unfailing bactericidal cocktails.

Sometimes you really can believe your eyes. That's what NASA's STEREO spacecraft are telling researchers about a controversial phenomenon on the sun known as the "solar tsunami." Years ago, when solar physicists first witnessed a towering wave of hot plasma racing along the sun's surface, they doubted their senses.

Chemists and physicists have succeeded in getting custom-shaped microparticles to interact and self-assemble in a controlled way in a liquid crystal.

CERN's Large Hadron Collider has been restarted and low-energy collisions were tested in the machine for the very first time.

Through the 1970s, physicists didn't believe that adding more carbon dioxide to the atmosphere would cause any warming because there was already enough carbon dioxide in the atmosphere to absorb all of the infrared radiation being reflected from the earth in the frequencies of infrared radiation that carbon dioxide absorbs and which don't overlap ...

The Japan News.Net Wednesday 25th November, 2009 London, November 25 : Particle physicists working on the T2K neutrino experiment in Japan have detected the first neutrinos, which are fundamental particles that are amongst the least understood in the Universe.

The studies used molecular dynamics flexible fitting to examine the interaction of the ribosome with two prominent molecular partners.

The Large Hadron Collider smashed its first proton beams together yesterday, three days after it was restarted following a 14-month shutdown for repairs.

Back in my college days, I took an introductory class in 20th-century quantum physics and its modern-day philosophical implications, sometimes deridingly referred to as "Physics for Poets." In order to make the materials marginally more approachable, the professor would draw liberally from the Klingons of "Star Trek" fame to make his points.

Physicists have shown that complicated quantum entanglements can be transformed into an arrangement where the entanglement fans out neatly from the hub qubit to each of the other qubits.

Two beams circulated simultaneously inside the Large Hadron Collider for the first time today, allowing for the first proton-proton collisions to take place.

Three physicists won the 2009 Nobel Prize on Tuesday for work on fibre optics and light sensing that helped unleash the Information Technology revolution.

Abstract Strong interactions between electrons in a solid material can lead to surprising properties.
