Hitting nuclei with light may create fluid primordial matter      (via sciencedaily.com) 

A new analysis supports the idea that photons colliding with heavy ions create a fluid of 'strongly interacting' particles. The results indicate that photon-heavy ion collisions can create a strongly interacting fluid that responds to the initial collision geometry and that these collisions can form a quark-gluon plasma. These findings will help guide future experiments at the planned Electron-Ion Collider.

Clear sign that quark-gluon plasma production 'turns off' at low energy      (via sciencedaily.com) 

Physicists report new evidence that production of an exotic state of matter in collisions of gold nuclei at the Relativistic Heavy Ion Collider (RHIC) can be 'turned off' by lowering the collision energy. The findings will help physicists map out the conditions of temperature and density under which the exotic matter, known as a quark-gluon plasma (QGP), can exist and identify key features of the phases of nuclear matter.

Heterostructures support predictions of counterpropagating charged edge modes at the v=2/3 fractional quantum Hall state      (via sciencedaily.com)     Original source 

Researchers have tested models of edge conduction with a device built on top of the semiconductor heterostructure which consists of gold gates that come close together. Voltage is applied on the gates to direct the edge states through the middle of the point contact, where they are close enough that quantum tunneling can occur between the edge states on opposite sides the sample. Changes in the electrical current flowing through the device are used to test the theorists' predictions.

In the very near future, quantum computers are expected to revolutionize the way we compute, with new approaches to database searches, AI systems, simulations and more. But to achieve such novel quantum technology applications, photonic integrated circuits which can effectively control photonic quantum states -- the so-called qubits -- are needed. Physicists have made a breakthrough in this effort: for the first time, they demonstrated the controlled creation of single-photon emitters in silicon at the nanoscale.
