New Zealand might be Australia’s smaller neighbor but it’s sitting on a massive new continent scientists have named “Zealandia,” according to a publication released by The Geological Society of America.

New Zealand and Australia might be able to finally give each other more breathing room. It turns out they sit on separate continents. New Zealand calls a 1.8 million square mile land mass known as Zealandia home. This new continent also includes New Caledonia, along with several other territories and island groups.

The idea of a potential continent in this area has been around for some time. Geophysicist Bruce Luyendyk coined the term Zealandia in 1995.

Nice research on finite temperatures and diamond structure spins.

Here the quantum criticality in the Ising-XXZ diamond structure at finite temperature have been studied by the trance distance discord calculations. Around the critical lines, the first-order derivative of the trace distance discord exhibits a maximal at a finite temperature and diverges under the thermodynamic limits T → 0. By analyzing the finite-temperature scaling behaviors, we show that the trace distance discord can detect exactly the quantum phase transition from the entangled state in ferrimagnetic phase to an unentangled state in ferrimagnetic phase or to an unentangled state in ferromagnetic phase. The results also show that the trace distance can distinguish the two kinds of transitions by consulting to the different finite-temperature scaling behaviors. As a comparison, we also study the behaviors of some other typical quantum correlations (e.g., concurrence, quantum discord and Hellinger distance) around the critical points, and the results state that the trance distance discord is more reliable than the others to spotlight the critical points for this Ising-XXZ diamond structure at finite temperatures.

Surely, this model system has three different critical phases, and it would be significant and challenging in the future to consider the multipartite quantum correlations which may grasp all these transitions. The bipartite quantum correlations imposed on this Ising-XXZ diamond structure, as studied in this work, can not detect the transition from UFI phase to UFM phase at finite temperature, an issue for future investigations.

Three researchers from the Defense Advanced Research Projects Agency make some predictions for the future.

Retail is dieing.

Buffett’s been paring his stake in Walmart since. He first bought shares in Walmart in 2005.

He said Amazon’s competitors, “including us in a few areas, have not figured the way to either participate in it, or to counter it.”

In Brief:

Researchers found out that human eyes can detect single photons when in the dark. Human eyes become more sensitive when subjected to darkness, making our eyes capable of doing a task that even high-tech machines struggle to perform.

Researchers from Rockefeller University and the University of Vienna recently discovered that human eyes can detect even the smallest units of light, called photons, under super-dark conditions. This is the first time that experts were able to show this capability of the human eye.
