Laser light hybrids control giant currents at ultrafast times
Circularly polarized laser pulse (a-c) versus a hencomb laser pulse (d-f). The vector potential of a circularly polarized lightwave applied to the two dimensional material Tungsten Diselenide generates no residual current after the laser pulse (a,b), solely exciting a valley charge state, (c), in which the Bloch velocities of all excited states cancel by virtue…

The ATLAS collaboration observes the electroweak production of two jets and a Z-boson pair
Display of one candidate signal event from the lllljj channel, reconstructed by the ATLAS detector. The green lines show the path of two opposite-charge electrons. The red lines show the path of two opposite-charge muons. The two jets in the forward and background region are shown as yellow cone. Copyright CERN for the benefit of…

Toward a deeper understanding of turbulence in elastoviscoplastic fluids
Dissipation in a Newtonian fluid (left) and an elastoviscoplastic fluid (right). Solid regions are shown in grayscale and liquid regions are shown in color. Credit: OIST Three-dimensional simulations shed light on how energy dissipates within non-Newtonian fluids (fluids in which viscosity depend on the shear rate.) The result is valuable in the context of disaster…

New kind of quantum transport discovered in a device combining high-temperature superconductors and graphene
(a) Schematic cross section of our device. GrΔ is superconducting graphene under BSCCO, Gr′ is a p-doped graphene, and Gr is native graphene. d is the length of Gr′. The dotted lines at either end of Gr′ denote the interfaces. (b) Optical micrograph of device A from Table 1. S is shorthand for BSCCO. The…

New light sheet holography overcomes the depth perception challenge in 3D holograms
By stacking 2D sheets of tightly controlled rays of light, researchers in the lab of Federico Capasso can depict 3D holographic objects. Credit: Harvard John A. Paulson School of Engineering and Applied Sciences Holography—the use of light projection to display images—can be used to construct holograms, which are three-dimensional structures of light that depict true-to-life…

Visualizing differences in nuclear structure
The horizontal axis represents the proton scattering angle and the vertical axis represents the ease with which protons are scattered. C-type and S-type are theoretical values assuming cluster and shell structure, respectively. Expt. is existing data. Credit: Wataru Horiuchi, OMU Helium usually has two protons and two neutrons strongly bound to each other, often forming…

Physics – Topological Superconductivity without Superconductors
April 13, 2023• Physics 16, s53 Researchers propose a way to relieve the material requirements needed to realize topological quantum computers. K. Mæland and A. Sudbø [1] K. Mæland and A. Sudbø [1] × Today’s quantum computers are delicate devices—sensitive to disruption by environmental noise. Physicists are thus pursuing alternatives called topological quantum computers, which…
