Unveiling the quantum necklace Thu, 25 May 2017 10:03:11 EDT
The quantum world is both elegant and mysterious. It is a sphere of existence where the laws of physics experienced in everyday life are broken -- particles can exist in two places at once, they can react to each other over vast distances, and they themselves seem confused over whether they are particles or waves. For those not involved in the field, this world may seem trifling, but recently, researchers have theoretically described two quantum states that are extraordinary in both the physics that define them and their visual appeal: a complex quantum system that simulates classical physics and a spellbinding necklace-like state.

One-dimensional crystals for low-temperature thermoelectric cooling Wed, 24 May 2017 10:15:16 EDT
Researchers studied the thermal and electrical properties of one-dimensional crystals composed of tantalum, silicon and tellurium for thermoelectric cooling at temperatures below 250 K (-23C).
