Published Researchers show a new way to induce useful defects using invisible material properties



Much of modern electronic and computing technology is based on one idea: add chemical impurities, or defects, to semiconductors to change their ability to conduct electricity. These altered materials are then combined in different ways to produce the devices that form the basis for digital computing, transistors, and diodes. Indeed, some quantum information technologies are based on a similar principle: adding defects and specific atoms within materials can produce qubits, the fundamental information storage units of quantum computing.
Published Chaos gives the quantum world a temperature


Two seemingly different areas of physics are related in subtle ways: Quantum theory and thermodynamics. How can the laws of thermodynamics arise from the laws of quantum physics? This question has now been pursued with computer simulations, which showed that chaos plays a crucial role: Only where chaos prevails do the well-known rules of thermodynamics follow from quantum physics.
Published Quantum dots at room temp, using lab-designed protein



Quantum dots are normally made in industrial settings with high temperatures and toxic, expensive solvents -- a process that is neither economical nor environmentally friendly. But researchers have now pulled off the process at the bench using water as a solvent, making a stable end-product at room temperature. Their work opens the door to making nanomaterials in a more sustainable way by demonstrating that protein sequences not derived from nature can be used to synthesize functional materials.
Published A peculiar protected structure links Viking knots with quantum vortices



Mathematical analysis identifies a vortex structure that is impervious to decay.
