(2015)
Dihadron correlations are analyzed in √SNN=200 GeVd+Au collisions classified by forward charged particle multiplicity and zero-degree neutral energy in the Au-beam direction. It is found that the jetlike correlated yield ...

(2015)
We introduce a mean-field and a perturbative approach, based on clusters, to describe the ground state of fermionic strongly correlated systems. In the cluster mean-field approach, the ground-state wave function is written ...

(2015)
Fusion of tubular membranes is required to form three-way junctions found in reticular subdomains of the endoplasmic reticulum (ER). The large GTPase Atlastin has recently been shown to drive ER membrane fusion and three-way ...

(2015)
We have engineered electron-hole bilayers of inverted InAs/GaSb quantum wells, using dilute silicon impurity doping to suppress residual bulk conductance. We have observed robust helical edge states with wide conductance ...

(2015)
The use of surface plasmons, charge density oscillations of conduction electrons of metallic nanostructures, to boost the efficiency of light-harvesting devices through increased light-matter interactions could drastically ...
