Physicists show standard 'quasiparticle' theory breaks down at 'quantum critical point'
A new study this week finds that "quantum critical points" in exotic electronic materials can act much like polarizing "hot button issues" in an election. Reporting in Nature, researchers from Rice University, two Max Planck ...

Bismuth-based semiconducting material could enable control of electron spin
In the developing field of spintronics, physicists are designing devices to transmit data using the inherent axial rotation, or spin, of electrons rather than their charge as is used in electronics. Weak coupling of electron ...

A closer look at ring opening: Electron diffraction studies of photoswitchable molecules
(PhysOrg.com) -- We use a switch to turn lights off and on; however, light can also act as a switch itself, for example when molecules change their structure upon irradiation. Photoswitchable molecules are potentially interesting ...
